In OTP-20.0, the behavior of c, make, and ct_make was
changed so that in some cases the beam files by default
would be written to the directory where the source files
were found. This is now changed back to the old behavior
so beam files are by default written to current
directory.</p>

<p>
* <c>connect/1,2</c> - establish an SSH connection *
<c>disconnect/1</c> - close the given SSH connection *

<p>The following corrections and improvements are done in
the common_test hook handling:</p> <list> <item> <p>An
extra argument, <c>Suite</c>, is added as the first
argument to each of the following hook callback
functions:</p> <list>
<item><c>pre_init_per_group</c></item>
<item><c>post_init_per_group</c></item>
<item><c>pre_end_per_group</c></item>
<item><c>post_end_per_group</c></item>
<item><c>pre_init_per_testcase</c></item>
<item><c>post_init_per_testcase</c></item>
<item><c>pre_end_per_testcase</c></item>
<item><c>post_end_per_testcase</c></item>
<item><c>on_tc_fail</c></item>
<item><c>on_tc_skip</c></item> </list> <p>For backwards
compatibility, if the new function is not exported from a
hook callback module, <c>common_test</c> will fall back
to the old interface and call the function without the
<c>Suite</c> argument.</p> </item> <item> <p>If either
<c>init_per_suite</c> or <c>end_per_suite</c> exists, but
not the other, then the non-existing function will be
reported as failed with reason <c>undef</c> in the test
log. The same goes for <c>init/end_per_group</c>. This
has always been a requirement according to the user's
guide, but now <c>common_test</c> is more explicit in the
report.</p> </item> <item> <p>If <c>init_per_suite</c>
was exported from a test suite, but not
<c>end_per_suite</c>, then <c>pre/post_end_per_suite</c>
was called with <c>Suite=ct_framework</c> instead of the
correct suite name. This is now corrected.</p> </item>
<item> <p>If <c>end_per_group</c> was exported from a
suite, but not <c>init_per_group</c>, then
<c>end_per_group</c> was never called. This is now
corrected.</p> </item> <item> <p>Tests that were skipped
before calling <c>pre_init_per_*</c> got faulty calls to
the corresponding <c>post_init_per_*</c>. E.g. if a test
was skipped because <c>suite/0</c> failed, then
<c>post_init_per_suite</c> would be called even though
<c>pre_init_per_suite</c> and <c>init_per_suite</c> were
not called. This is now corrected so a <c>post_*</c>
callback will never be called unless the corresponding
<c>pre_*</c> callback has been called first.</p> </item>
<item> <p>Tests that were skipped before or in
<c>init_per_testcase</c> got faulty calls to
<c>pre_end_per_testcase</c> and
<c>post_end_per_testcase</c>. This is now corrected so
<c>pre/post_end_per_testcase</c> are not called when
<c>end_per_testcase</c> is not called.</p> </item> <item>
<p>If an exit signal causes the test case process to die
while running <c>init_per_testcase</c>, the case was
earlier reported as failed with reason <c>{skip,...}</c>.
This is now corrected so the case will be marked as
skipped.</p> </item> <item> <p>If an exist signal causes
the test case process to die while running
<c>end_per_testcase</c>, the case was earlier marked as
failed. This is now corrected so the status of the test
case is not changed - there is only a warning added to
the comment field.</p> </item> <item> <p>If a test case
was skipped because of option
<c>{force_stop,skip_rest}</c> or because of a failed
sequence, then no <c>tc_start</c> event would be sent,
only <c>tc_done</c>. This is now corrected so both events
are sent.</p> </item> <item> <p>When skipping or failing
in a configuration function, the configuration function
itself would get <c>{auto_skipped,Reason}</c>,
<c>{skipped,Reason}</c> or <c>{failed,Reason}</c> in the
hook callbacks <c>on_tc_skip</c> or <c>on_tc_fail</c>.
The other test cases that were skipped as a result of
this would only get <c>Reason</c> in <c>on_tc_skip</c>.
This is now corrected so even the configuration function
that caused the skip/fail will only get <c>Reason</c> in
the hook callback.</p> </item> </list>

When a test case was skipped by a <c>skip_cases</c>
statement in a test spec, then <c>cth_surefire</c> would
erroneously mark the previous test case as skipped in the
xml report. The actually skipped test case would not be
present in the xml report at all. This is now corrected.</p>

Some types of printouts to screen during test runs
(including <c>ct:print/1,2,3,4</c>) used the local
<c>user</c> process as IO device and these printouts
would not be visible when e.g. running tests via a shell
on a remote node. A default Common Test group leader
process has been introduced to solve the problem. This
process routes printouts to the group leader of the
starting process, if available, otherwise to <c>user</c>.</p>

The logging verbosity feature was incorrectly documented.
The default verbosity levels for test runs is e.g. not 50
(<c>?STD_VERBOSITY</c>), but 100 (<c>?MAX_VERBOSITY</c>).
Also, some of the examples had errors and flaws. The
corresponding chapter (5.18) in the User's Guide has been
updated.</p>

argument to <c>ct:pal/3,4,5</c>, <c>ct:print/3,4,5</c>,
or <c>ct:log/3,4,5</c>. If the heading option is omitted,
the category name, or <c>"User"</c>, is used as the
heading instead.</p>

The <c>nodelay</c> option used to be enabled
(<c>true</c>) by default for sockets opened by the Common
Test telnet client. This appeared to cause communication
problems with telnet servers on some systems, and
therefore the option is no longer used. Its value may
instead be specified in the telnet connection settings.
See the man page for <c>ct_telnet</c> for details. Please
note that the interface function <c>connect</c> in
<c>unix_telnet</c> has been updated with an extra
argument and is now <c>unix_telnet:connect/7</c>.</p>

The <c>ct_run</c> start flag <c>-no_esc_chars</c> and
<c>ct:run_test/1</c> start option <c>{esc_chars,Bool}</c>
have been introduced to make it possible to disable
automatic escaping of characters. Automatic escaping of
special HTML characters printed with <c>io:format/1,2</c>
and <c>ct:pal/1,2,3,4</c> was introduced in Common Test
1.12. The new flag/option may be used to disable this
feature for backwards compatibility reasons. (The option
is also supported in test specifications).</p>

This update fixes the problem with generic printouts in
the html log file not having special characters escaped.
Printouts made with <c>io:format/2</c> and
<c>ct:pal/2</c> will now get special characters escaped
automatically. Common Test will not attempt to escape
characters printed with <c>ct:log/2</c> since it is
assumed that the user may want to print html tagged data
using this function. A new function, <c>ct:log/5</c>, has
been added, which offers optional escaping of characters.
The latter function may also be used to print text to the
log without headers and CSS class wrapping (analogue to
<c>io:format/2</c>).</p>

If a ssh package contained more than one netconf end tag,
then the second end tag was never detected in

In ct_netconfc, if a timer expired 'at the same time' as
the server sent the rpc-reply, the timeout message might
already be in the client's message queue when the client
removed the timer ref from its 'pending' list. This
caused a crash in the client since the timer ref could no
longer be found when handling the timeout message. This
problem is now fixed by always flushing the timeout
message from the message queue when canceling a timer.</p>

When running OTP tests using the ts interface, it is now
possible to specify so called test categories per OTP
application. A test category is represented by a CT test
specification and defines an arbitrary subset of existing
test suites, groups and cases. Examples of test
categories are 'smoke' (smoke tests) and 'bench'
(benchmarks). (Call ts:help() for more info). Also,
functions for reading terms from the current test
specification during test, ct:get_testspec_terms/0 and
ct:get_testspec_terms/1, have been implemented.</p>

The 'keep_alive' interval has been reduced to 8 seconds,

the telnet server receives a NOP message (which might
trigger an action) before the operation times out. Also
the TCP option 'nodelay' has been enabled per default for
all telnet connections, in order to reduce the risk for
communication timeouts.</p>

If the last expression in a test case causes a timetrap
timeout, the stack trace is ignored and not printed to
the test case log file. This happens because the
{Suite,TestCase,Line} info is not available in the stack
trace in this scenario, due to tail call elimination.
Common Test has been modified to handle this situation by
inserting a {Suite,TestCase,last_expr} tuple in the
correct place and printing the stack trace as expected.</p>

When a test case (or configuration function) fails
because of an exit signal from a linked process, Common
Test previously passed only the reason for process
termination to the CT post hook functions and the event

that now the tuple {'EXIT',ReasonForProcessTermination}
is passed instead. This makes it much easier in the CT
post hook functions to distinguish a failure of this sort
from other types of errors and from the return value of a
successful test case.</p>

The mechanism for running code cover analysis with
common_test has been improved. Earlier, if a test run
consisted of multiple tests, cover would be started and
stopped for each test. This would give "intermediate"
cover logs available from the "Coverage log" link on the
test suite result pages. To accumulate cover data over
all tests, the 'export' option had to be used in the
cover spec file. This was not well documented, and the
functionality was quite confusing.</p>
<p>
Using the 'nodes' option in the cover spec file would
fail when the test run consisted of multiple tests, since
the specified nodes would only be included in the cover
analysis of the first test.</p>
<p>
The repeated compilation and analysis of the same modules
was also very time consuming.</p>
<p>
To overcome these problems, ct will now only cover
compile and analyze modules once per test run, i.e. once
for each cover spec file. The log file is available via a
new button on the top level index page. The old "Coverage
log" links on the test suite result pages still exist,
but they all point to the same log containing the
accumulated result.</p>

<p>The way Common Test handles skipping of test cases has
been updated. In previous versions, returning
<c>{skip,Reason}</c> from a configuration function (such
as init_per_suite or init_per_group), resulted in all
affected test cases getting skipped with status
<c>auto_skipped</c>. This was inappropriate, since this
status is supposed to be used to inform that Common Test
has taken the initiative to skip something (e.g. a test
case group if init_per_group failed). Therefore, in this
version of Common Test, whenever the user skips a suite,
group, or individual test case (by means of a
configuration function or test specification term), the
affected test cases get the status <c>user_skipped</c>
instead.</p> <p>This update has meant a few changes that
may affect Common Test users in various ways:</p> <list>

which is important to know when running regression tests
and comparing results to previous test runs.</item>

If a telnet connection is hanging, then a call to

connection process is brutally killed. In some cases the
connection would not be unregistered and attempts at

common_test try to reuse the same connection since it
believed that it was still alive. This has been corrected
- a killed connection is now always unregistered.</p>

Test performance has been improved by means of a cache

problems with slow start up times and test execution

stored in logdir. The cached index entries are stored in

Integrate elliptic curve contribution from Andreas
Schultz </p>
<p>
In order to be able to support elliptic curve cipher
suites in SSL/TLS, additions to handle elliptic curve
infrastructure has been added to public_key and crypto.</p>
<p>
This also has resulted in a rewrite of the crypto API to
gain consistency and remove unnecessary overhead. All OTP
applications using crypto has been updated to use the new
API.</p>
<p>
Impact: Elliptic curve cryptography (ECC) offers
equivalent security with smaller key sizes than other
public key algorithms. Smaller key sizes result in
savings for power, memory, bandwidth, and computational
cost that make ECC especially attractive for constrained
environments.</p>

If an event handler installed in the CT Master event

<p>In test_server, the same process would supervise the
currently running test case and be group leader (and IO
server) for the test case. Furthermore, when running
parallel test cases, new temporary supervisor/group
leader processes were spawned and the process that was
group leader for sequential test cases would not be
active. That would lead to several problems:</p>
<p>* Processes started by init_per_suite will inherit the
group leader of the init_per_suite process (and that
group leader would not process IO requests when parallel
test cases was running). If later a parallel test case
caused such a processto print using (for example)
io:format/2, the calling would hang.</p>
<p>* Similarly, if a process was spawned from a parallel
test case, it would inherit the temporary group leader
for that parallel test case. If that spawned process
later - when the group of parallel tests have finished -
attempted to print something, its group leader would be
dead and there would be <c>badarg</c> exception.</p>
<p>Those problems have been solved by having group
leaders separate from the processes that supervises the
test cases, and keeping temporary group leader process
for parallel test cases alive until no more process in
the system use them as group leaders.</p>
<p>Also, a new <c>unexpected_io.log</c> log file
(reachable from the summary page of each test suite) has
been introduced. All unexpected IO will be printed into
it(for example, IO to a group leader for a parallel test
case that has finished).</p>

<p>It is now possible to let a test specification include
other test specifications. Included specs can either be
joined with the source spec (and all other joined specs),
resulting in one single test run, or they can be executed
in separate test runs. Also, a start flag/option,
<c>join_specs</c>, has been introduced, to be used in
combination with the <c>spec</c> option. With
<c>join_specs</c>, Common Test can be told to either join
multiple test specifications, or run them separately.
Without <c>join_specs</c>, the latter behaviour is
default. Note that this is a change compared to earlier
versions of Common Test, where specifications could only
be joined. More information can be found in the Running

If a CT hook function caused a crash, this could in some
situations cause Common Test to terminate due to an
illegal IO operation. This error has been corrected.</p>

<p>
The Common Test documentation states that timetraps are
never active during execution of CT hook functions. This
was only true for post hook functions, not for pre hook
functions. The code for CT hooks has been modified to
behave according to the documentation.</p>
<p>

<p>
If a CT hook function would call the exit/1 or throw/1
BIF (possibly indirectly, e.g. as a result of a timeout
in gen_server:call/3), Common Test would hang. This
problem has been fixed.</p>

It is now possible to specify an arbitrarily large tuple
as the requires config data when using require and
ct:get_config. See the ct:get_config and ct:require
reference manual pages for details about which keys are
allowed.</p>
<p>
This change introduces a backwards incompatability in the
<c>ct:require/2</c> interface. Previously when doing
<c>ct:require(a_name,{key,subkey})</c>, a_name would be
associated with key. This has been changed to that
<c>a_name</c> is associated with <c>subkey</c>. This
change also effects using <c>require</c> in an
suite/group/testcase info function.</p>

It is now possible to sort the HTML tables by clicking on
the header elements. In order to reset a sorted table,
the browser window should simply be refreshed. This
feature requires that the browser supports javascript,
and has javascript execution enabled. If the 'ct_run

A netconf client, ct_netconfc, is added to common_test.
It supports basic netconf functionality over SSH. In
order to allow testing of both success and failure cases,
it is intentionally written to allow non-standard
behavior.</p>
<p>

The test specification term {define,Constant,Value} has
been introduced, which makes it possible to replace
constant names (atom()) with values (term()) in arbitrary
test specification terms. The 'define' makes the (now
deprecated) 'alias' term obsolete. More details,
including examples, can be found in the Test
Specifications chapter in the Common Test User's Guide.</p>

<p>
Verbosity levels for log printouts has been added. This
makes it possible to specify preferred verbosity for
different categories of log printouts, as well as general
printouts (such as standard IO), to allow control over
which strings get printed and which get ignored. New
versions of the Common Test logging functions, ct:log,
ct:pal and ct:print, have been introduced, with a new
Importance argument added. The Importance value is
compared to the verbosity level at runtime. More
information can be found in the chapter about Logging in

The return values of ct:run_test/1 and ct:run_testspec/1
have been changed from an uninformative 'ok' (independent
of the test outcome) to a value,
{Ok,Failed,{UserSkipped,AutoSkipped}} (all integers),
that presents the final test case result, or a value,
{error,Reason}, that informs about fatal test execution
failure. See details in the reference manual for ct.</p>

Common Test adds the test suite directories to the code
path before executing the tests. These directories should
also be removed from the code path at the end of the test
run, which, prior to this fix, was not performed.</p>

An entry is now created in the index.html file (i.e. the
overview file for the test run) for each repeated test
during a test run. This was previously not the case. Note
that in the top level (logdir) index file, however, only
the last test result is listed. For example, given the
test spec:
[{merge_tests,false},{dirs,"test1"},{dirs,"test1"}]. In
the index file for the test run (under
Logdir/ct_run.Node.Date.Time), both tests are listed. In
the top level index file (under Logdir), only the last
test is listed (one has to find the previous results
through the all_runs.html file).</p>

After a test case timeout or abortion, the
end_per_testcase function executes on a new dedicated
process. The group leader for this process should be set
to the IO server for the test case, which was not done
properly. The result of this error was that no warnings
about end_per_testcase failing or timing out were ever
printed in the test case log. Also, help functions such
as e.g. test_server:stop_node/1, attempting to
synchronize with the IO server, would hang. The fault has
been corrected.</p>

Two or more test cases executing in parallel and printing
to screen at the same time with ct:pal/2/3 or

When starting a test with ct_run and adding a directory
to the code path using -pa or -pz (preceding -erl_args),

A new optional feature has been introduced that enables
Common Test to generate priv_dir directory names that are
unique for each test case or config function. The name of
the option/flag is 'create_priv_dir' and it can be set to
value 'auto_per_run' (which is the default, existing,
behaviour), or 'auto_per_tc' or 'manual_per_tc'. If
'auto_per_tc' is used, Test Server creates a dedicated
priv_dir automatically for each test case (which can be
very expensive in case of many and/or repeated cases). If
'manual_per_tc' is used, the user needs to create the
priv_dir explicitly by calling the new function
ct:make_priv_dir/0.</p>

Common Test will now print error information (with a time

If the init_per_group/2 and end_per_group/2 functions are
not implemented in the test suite, Common Test calls it's
own local init- and end functions - previously named
ct_init_per_group/2 and ct_end_per_group/2 - when a group
is executed. These functions have been renamed
init_per_group/2 and end_per_group/2 respectively. Note
that this may affect any user event handler identifying

The test case group info function has been implemented in
Common Test. Before execution of a test case group, a
call is now made to <c>TestSuite:group(GroupName)</c>.
The function returns a list of test properties, e.g. to
specify timetrap values, require configuration data, etc
(analogue to the test suite- and test case info
function). The scope of the properties set by
<c>group(GroupName)</c> is all test cases and sub-groups
of group <c>GroupName</c>.</p>

Common Test hooks are now in a final supported version.
The Common Test hooks allow you to abstract out
initialization behaviour that is common to multiple test
suites into one place and also extend the behaviour of a
suite without changing the suite itself. For more
information see the Common Test user's guide.</p>

A new built-in common test hook has been added which

Common Test now calls info functions also for the
<c>init/end_per_suite/1</c> and
<c>init/end_per_group/2</c> configuration functions.
These can be used e.g. to set timetraps and require
external configuration data relevant only for the
configuration functions in question (without affecting
properties set for groups and test cases in the suite).
The info function for <c>init/end_per_suite(Config)</c>
is <c>init/end_per_suite()</c>, and for
<c>init/end_per_group(GroupName,Config)</c> it's
<c>init/end_per_group(GroupName)</c>. Info functions can
not be used with <c>init/end_per_testcase(TestCase,
Config)</c>, since these configuration functions execute
on the test case process and will use the same properties
as the test case (i.e. properties set by the test case
info function, <c>TestCase()</c>).</p>

It's now possible to read the full name of the test case
log file during execution. One way to do this is to
lookup it up as value of the key <c>tc_logfile</c> in the
test case <c>Config</c> list (which means it can also be
read by a pre- or post Common Test hook function). The
data is also sent with the event
<c>#event{name=tc_logfile,data={{Suite,Func},LogFileName}}</c>,

Printouts to stdout may be captured during test case
execution. This is useful in order to e.g. read and parse
tty printouts from the SUT during test case execution (if
necessary, say, to determine the outcome of the test).
The capturing session is started with
<c>ct:capture_start/0</c>, and stopped with
<c>ct:capture_stop/0</c>. The list of buffered strings is
read and purged with <c>ct:capture_get/0/1</c>. It's
possible to filter out printouts made with
<c>ct:log/2/3</c> and <c>ct:pal/2/3</c> from the captured
list of strings. This is done by calling
<c>capture_get/1</c> with a list of log categories to

The syntax for specifying test case groups in the all/0
list has been extended to include execution properties
for both groups and sub-groups. The properties specified
in all/0 for a group overrides the properties specified
in the group declaration (in groups/0). The main purpose
of this extension is to make it possible to run the same
set of tests, but with different properties, without
having to declare copies of the group in question. Also,
the same syntax may be used in test specifications in
order to change properties of groups at the time of
execution, without having to edit the test suite. Please
see the User's Guide for details and examples.</p>

If a timetrap timeout occured during execution of of a

module. (This would only happen if the lib module was

Corrections of the vts mode. It will now report errors
(about e.g. incorrect config files) instead of crashing
or hanging. Furthermore, the requirement that the test
directory name must have a "_test" suffix has been
removed. Also, a workaround has been implemented for the
limitation that the file browser (in many web browsers)
will only return the basic file name, not the full
directory path (which made it impossible to have config
files in other directories than the main test directory).</p>

defined without the init_per_group/2 and end_per_group/2
function, init_per_suite/1 would not execute initially
and logging of the test run would fail. This error has

The dir and suite start option can now be used in
combination. E.g. executing my_SUITE in directory
my_tests can either be specified as "ct_run -suite
my_tests/my_SUITE" or as "ct_run -dir my_tests -suite
my_SUITE". Furthermore, the specification:
ct:run_test([{suite,["./my_SUITE"]},{testcase,t1}]) is
now interpreted as
ct:run_test([{suite,"./my_SUITE"},{testcase,t1}]), i.e.
only testcase t1 in test suite my_SUITE - not all cases -
will be executed.</p>

A new option, 'logopts', has been introduced, to make it
possible to modify some aspects of the logging behaviour
in Common Test (or Test Server). For example, whenever an
io printout is made, test_server adds newline (\n) to the
end of the output string. This may not always be a
preferred action and can therefore be disabled by means
of "ct_run ... -logopts no_nl" (or ct:run_test([...,
{logopts,[no_nl]}])). A new framework callback function,
get_logopts/0, has been introduced (see the ct_framework
module for details).</p>

ct:run_test([..., {logopts,[no_src]}])). A new framework
callback function, get_logopts/0, has been introduced

It is now possible for the user to provide specific
callback modules that handle test configuration data, so
that data on arbitray form can be accessed (e.g. by
reading files or by communicating with a configuration
server process). Two default callback modules have been
introduced in Common Test: ct_config_plain and
ct_config_xml. The former is used to handle the
traditional Common Test configuration files (with terms
on key-value tuple form) and the latter to handle
configuration data on XML representation.</p>

It is now possible to execute test suites that are not
necessarily available on the local file system, but have
been loaded on the test node in advance (e.g. sent as
binaries from a remote node and loaded by RPC). A
requirement is that the no_auto_compile (or
{auto_compile,false}) parameter has been set.</p>

Test Server will now call the end_per_testcase/2 function
even if the test case has been terminated explicitly
(with abort_current_testcase/1), or after a timetrap
timeout. Under these circumstances the return value of
end_per_testcase is completely ignored. Therefore the
function will not be able to change the reason for test
case termination by returning {fail,Reason}, nor will it
be able to save data with {save_config,Data}.</p>

perform host login and node startup operations over ssh.</p>

Previously, a repeat property of a test case group
specified the number of times the group should be
repeated after the main test run. I.e. {repeat,N} would
case the group to execute 1+N times. To be consistent
with the behaviour of the run_test repeat option, this
has been changed. N now specifies the absolute number of
executions instead.</p>

With the run_test -erl_args option, it's possible to
divide the options on the run_test command line into ones
that Common Test should process (those preceding
-erl_args, and ones it should ignore (those succeeding
-erl_args). Options preceding -erl_args that Common Test
doesn't recognize are also ignored (i.e. the same
behaviour as earlier versions of Common Test).</p>

The timetrap handling has been made more user
controllable by means of new start options and new ct
interface functions. With the 'multiply_timetraps' start
option, it's possible to specify a value which all
timetrap timeout values get multiplied by. This is useful
e.g. to extend the timetraps temporarily while running
cover or trace. The 'scale_timetraps' start option
switches on or off the Test Server timetrap scaling
feature (which tries to detect if the tests may benefit
from extended timetraps, e.g. due to running certain test
tools, and performs the scaling automatically).
Furthermore, the ct:timetrap/1 function has been
introduced, which makes it possible to set/reset
timetraps during test execution. Also, a ct:sleep/1
function is now available, which takes the timetrap
parameters into account when calculating the time to
suspend the process.</p>

The telnet client in Common Test sent [IAC,DO,NOP] to the
server in attempt to keep the connection alive. This is
not a valid sequence according to the standard, and some
telnet servers would terminate the connection because of
it. The client has been changed to send [IAC,NOP] every
10 secs instead, which should be a valid sequence. The
client does not negotiate this type of "keep alive"
message with the server, and if it causes problems, the
user may disable the keep alive feature by adding
{keep_alive,false} to the telnet configuration data for
the server/connection. Please see the ct_telnet and
unix_telnet manual pages for details.</p>

sub-directory only if the directory exists. Otherwise it

the user specifies with e.g. the 'dir' start flag/option.</p>

Test case groups have been introduced. With this feature
it's possible to execute groups (possibly nested) of test
cases, each group wrapped with a call to function
init_per_group/2 and end_per_group/2. Group definitions
are done by means of the new call-back function groups/0,
which should return a list of definitions. A group
definition contains a name tag, a list of properties and
a list of test cases (including possible nested group
definitions). The properties make it possible to execute
test cases in parallel, in sequence and in shuffled
order. It is also possible to repeat test cases according
to different criterias. The properties can be combined,
making it possible to e.g. repeat a conf case a certain
number of times and execute the test cases in different
(random) order every time. Available properties are:
parallel, sequence, shuffle, repeat, repeat_until_all_ok,
repeat_until_any_ok, repeat_until_any_fail and
repeat_until_all_fail. Please see the Common Test User's

It is now possible for the user to specify include
directories that Common Test will pass along to the
compiler when suite and help modules are being compiled
(which Common Test performs automatically before running
tests).</p>

If the Erlang runtime system was started without access
to an erlang shell (e.g. -noshell), compilation errors
would cause a crash in the Common Test application.
Without access to a shell, Common Test can not prompt the
user to choose to continue or abort the test session, but
must assume that the session should proceed.</p>

It is now possible for the Common Test user to disable
the auto-compile feature. This is done by specifying the
run_test flag -no_auto_compile, or the ct:run_test/1
option {auto_compile,false}.</p>

A new function, ct:get_config/3, has been added to Common
Test that makes it possible to - if a particular config
variable has been defined in multiple config files -
return all matching values for the variable. The order of
the elements in the returned list is the same as the
specified order of the config files.</p>

Because a telnet connection was always identified by a
config variable alias, it was impossible to open multiple
connections using the same telnet host data entry in the
config file. This limitation has been removed by making
it possible to associate a connection with handle value
only (i.e. multiple connections may be opened using the
same config variable). See ct_telnet:open/4 for details.</p>

A new syntax for defining default config data values has
been introduced. In previous versions of Common Test, to
define and access a default value for a config variable
(in the suite info- or test case info function), an alias
name had to be used. With the new syntax you may define
default values without reference to aliases, like this:
{default_config,VarName,DefaultValue}. Please see the
User's Guide for more info.</p>

In previous versions of Common Test, whenever a config
variable got associated with a name (by means of a
require statement), the config variable name was replaced
with the new name. This introduced unwanted dependencies
between test cases (e.g. if one test case would introduce
a new name, the following test cases could no longer
access the config data by means of the original
variable). This functionality has now been updated so
that when new names are introduced with require, they
become aliases (references) instead of replacements.
Hence, config data elements can always, at any time, be
accessed by means of the original config variable names.</p>

Common Test now uses the re application instead of the
previous rx driver to perform regular expression matching
on telnet strings. Since re works on all supported
operating systems, it is now possible to run telnet
sessions also on platforms such as e.g. Windows (which
was not the case with the previous rx driver). Note that
the rx driver is obsolete from now on, and will be
removed from Common Test after OTP R12B.</p>

The configure test of the rx lib in Common Test was not
performed during the general OTP application
configuration phase. This made e.g. autoconf impossible.
This has been changed to correspond with the normal OTP
build procedure.</p>
