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>

It is now possible to use the test specification term
'init' to start Common Test nodes automatically, as well
as have initial function calls evaluated on the nodes. A
default callback module for the 'init' term, ct_slave,
has been introduced to enable Common Test Master to
perform host login and node startup operations over ssh.</p>

The run_test script has been replaced by a program (with

installation. The start flags are the same as for the
legacy start script.</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>

<p>
Directories added with -pa or -pz in the pre-erl_args
part of the run_test command line will be converted from
relative to absolute, this to avoid problems loading user
modules when Common Test switches working directory
during the test run.</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>

A new run_test start option, event_handler_init, has been

<p>The documentation is now possible to build in an open
source environment after a number of bugs are fixed and
some features are added in the documentation build
process. </p>
<p>- The arity calculation is updated.</p>
<p>- The module prefix used in the function names for
bif's are removed in the generated links so the links
will look like
"http://www.erlang.org/doc/man/erlang.html#append_element-2"
instead of
"http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".</p>
<p>- Enhanced the menu positioning in the html
documentation when a new page is loaded.</p>
<p>- A number of corrections in the generation of man
pages (thanks to Sergei Golovan)</p>
<p>- The legal notice is taken from the xml book file so
OTP's build process can be used for non OTP
applications.</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>

Various updates of the test events have been implemented.
The data field for some events, such as tc_done and
tc_auto_skip has been modified to make pattern matching
on the data easier and more consistent. Also the order in
which some events are received has been altered. E.g. the
tc_auto_skip event for a test case now comes after the
tc_done for the failed configuration function (not
before) which makes more sense. Note that no new events
have been added and that the event record remains
unchanged.</p>

It is now possible to refresh the top level index files
in an arbitrary log directory by specifying a
{refresh_logs,LogDir} tuple in the ct:run_test/1 options
list. Also the -refresh_logs flag for the run_test script
has been extended to take an optional LogDir argument,
i.e. -refresh_logs [LogDir]. If no LogDir is specified,
current working directory is assumed, unless the log
directory is set with the -logdir flag.</p>

It was previously required that test suites were located
under a test object (or OTP application) sub-directory
named "test" (or under a directory named
"<testobject>_test"). This has been changed so that
Common Test now looks for suites primarily in a test
sub-directory only if the directory exists. Otherwise it
will assume the suites are stored in the same directory
the user specifies with e.g. the 'dir' start flag/option.</p>

The Common Test HTML overview pages have been improved.
It is now possible to see if a test case has been skipped
explicitly or because a configuration function has
failed. Also, the history page (all_runs.html) now has
scrolling text displaying the test names. The old format
(showing names as a truncated string) can still be
generated by means of the flag/option 'basic_html'.</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
Guide for details.</p>

When running a test which includes all suites in a test
directory, if the auto compilation would fail for one
suite, all following suites would be excluded from the
test. This was an unwanted behaviour and has been
corrected. Now all suites will always be compiled and
only the failing ones excluded from the test (and logged
as missing).</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

must assume that the session should proceed.</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>

<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>
<p>
Own Id: OTP-7782</p>
</item>
<item>
<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

was not the case with the previous rx driver). Note that
the rx driver is obsolete from now on, and will be
