<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>

<p>
A deadlock situation could occur if Common Test is
forwarding error_handler printouts to Test Server at the
same time a new test case is starting. This error has
been fixed.</p>

</item>
<item>
<p>
When a test case was killed because of a timetrap
timeout, the current location (suite, case and line) was
not printed correctly in the log files. This has been
corrected.</p>

<p>
Test Server and Common Test would add new error handlers
with each test run and fail to remove previously added
ones. In the case of Test Server, this would only happen
if SASL was not running on the test node. This has been
fixed.</p>
<p>

<p>
If a test case process was terminated due to an exit
signal from a linked process, Test Server failed to
report the correct name of the suite and case to the
framework. This has been corrected.</p>

<item>
<p>
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>
<p>

<p>
Own Id: OTP-9730 Aux Id: seq11952 </p>

<item>
<p>
It is now possible to use the post_end_per_testcase CT
hook function to print a comment for a test case in the
overview log file, even if the test case gets killed by a
timetrap or unknown exit signal, or if the
end_per_testcase function times out.</p>
<p>
Own Id: OTP-9855 Aux Id: seq11979 </p>
</item>
<item>
<p>
Common Test will now print error information (with a time
stamp) in the test case log file immediately when a test
case fails. This makes it easier to see when, in time,
the fault actually occured, and aid the job of locating
relevant trace and debug printouts in the log.</p>

Test Server has been modified to check the SASL
errlog_type parameter when receiving an error logger

By specifying a user defined function ({M,F,A} or fun) as
timetrap value, either by means of an info function or by

timetrap that will be triggered when the user function
returns.</p>

If the optional configuration functions init_per_suite/1
and end_per_suite/1 are not implemented in the test
suite, local Common Test versions of these functions are
called instead, and will be displayed in the overview log
file. Any printouts made by the pre- or
post_init_per_suite and pre- or post_end_per_suite hook
functions are saved in the log files for these functions.</p>

<p>
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>

<item>
<p>
If end_per_testcase caused a timetrap timeout, the actual
test case status was discarded and the test case logged
as successful (even if the case had actually failed
before the call to end_per_testcase). This fault has been
fixed.</p>
<p>
Own Id: OTP-9397</p>
</item>
<item>
<p>
If a timetrap timeout occured during execution of of a
function in a lib module (i.e. a function called directly
or indirectly from a test case), the Suite argument in
the end_tc/3 framework callback function would not
correctly contain the name of the test suite, but the lib
module. (This would only happen if the lib module was
compiled with ct.hrl included). This error has been
solved.</p>

If a test suite would start with a test case group
defined without the init_per_group/2 and end_per_group/2

<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>

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, if the html
version of the test suite source code should not be
generated during the test run (and consequently be
unavailable in the log file system), the feature may be
disabled by means of "ct_run ... -logopts no_src" (or
ct:run_test([..., {logopts,[no_src]}])). A new framework
callback function, get_logopts/0, has been introduced
(see the ct_framework module for details).</p>

It is now possible to use a tuple {M,F,A}, or a fun, as

case info functions. The function must return a valid

and in the User's Guide.</p>

<p>
When running tests with auto-compilation disabled, Common
Test could only display the test suite source code on
html format in the test case log if the source file was
located in the same directory as the pre-compiled suite.
This has been modified so that Common Test now tries to
locate the source file by means of the test suite module
info (Suite:module_info/1). As a result, a suite may now
be compiled to a different output directory (e.g.
$MYTEST/bin) than the source code directory (e.g.
$MYTEST/src), without the source-code-to-html generation
being affected.</p>

Alpha release of Common Test Hooks (CTH). CTHs allow the
users of common test to abtract out common behaviours
from test suites in a much more elegant and flexible way
than was possible before. Note that the addition of this
feature may introduce minor changes in the undocumented
behaviour of the interface inbetween common_test and
test_server.</p>

even if the test case has been terminated explicitly
(with abort_current_testcase/1), or after a timetrap

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>

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>

The conf case in Test Server has been extended with
properties that make it possible to execute test cases in
parallel, in sequence and in shuffled order. It is now
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. The properties are specified in a list
in the conf case definition: {conf, Properties, InitCase,
TestCases, EndCase}. The available properties are:
parallel, sequence, shuffle, repeat, repeat_until_all_ok,
repeat_until_any_ok, repeat_until_any_fail,
repeat_until_all_fail.</p>
