The auto compilation feature of Common Test did not
recognize if a header file included in a test suite was
modified (if the dir start flag/option was used). This
has been fixed.</p>

<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>

<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>

For a failed test case, the tc_done event is supposed to
report info on the form {failed,Error}. Only Error was
reported, however, which has now been fixed.</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>

The marquee used for test names on the all_runs.html page
has been removed on request. Note that the test name
field has the full text string in a title tag, which is
displayed when hovering the mouse pointer over it (i.e.
if the web browser supports title tags).</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>

<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>

<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>

supported.</p>

The Erlang mode for Emacs has been updated with new and

test case groups in Common Test (and conf cases with
properties in TS) has been added and a new minimal Common
Test suite skeleton has been introduced.</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
user to choose to continue or abort the test session, but
must assume that the session should proceed.</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>
<p>
Own Id: OTP-7758 Aux Id: seq11158 </p>

<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>
Own Id: OTP-7781</p>
</item>
<item>
<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
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>
