<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>

<p>
An error in how comments are colored in the test suite
overview html log file has been corrected. As result, a
new framework callback function, format_comment/1, has
been introduced.</p>

Test Server did not release SASL TTY handlers

<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>

</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
function, init_per_suite/1 would not execute initially
and logging of the test run would fail. This error has
been fixed.</p>

<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>

<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>

<p>
It is now possible to use a tuple {M,F,A}, or a fun, as
timetrap specification in the suite info function or test
case info functions. The function must return a valid
timeout value, as documented in the common_test man page
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>

<p>
It is now possible to return a tuple {fail,Reason} from
init_per_testcase/2. The result is that the associated
test case gets logged as failed without ever executing.</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>

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>

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>

<p>The documentation is now possible to build in an open

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 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>

Test Server is a portable test server for automated
application testing. The server can run test suites on
local or remote targets and log progress and results to
HTML pages. The main purpose of Test Server is to act as
engine inside customized test tools. A callback interface
for such framework applications is provided.</p>
