ct_netconfc:close_session sometimes returned
{error,closed} because the ssh connection was closed
(from the server side) before the rpc-reply was received
by the client. This is normal and can not be helped. It
has been corrected so the return will be 'ok' in this
case. Other error situations will still give
{error,Reason}.</p>

A new test case group search functionality has been
implemented that makes Common Test search automatically
through the group definitions tree (the return value of
groups/0) and create tests for all paths of nested groups
that match the specification. It also allows for
specifying unique paths to sub groups in order to avoid
execution of unwanted tests. This new feature can be used
whenever starting a test run by means of the ct_run
program, the ct:run_test/1 API function, or a Test
Specification. Details can be found in the Test Case
Group Execution section in the Running Tests chapter.</p>

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>
Own Id: OTP-10069</p>
</item>
<item>
<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>
<p>

The documentation has been updated with information about
how to deal with chaining of hooks which return
fail/skip.</p>

<p>
When ct_hooks called the id/1 functions of multiple
hooks, it would reverse the order of the hooks and call
the proceeding init/2 calls in the wrong order. This has
been fixed.</p>

The support for "silent connections" has been updated to
include ssh. Also, a silent_connections term has been
added to the set of test specification terms.</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>

before it ends. Value 0 indicates a successful test
result, 1 indicates one or more failed or auto-skipped
test cases, and 2 indicates test execution failure.</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
-basic_html' flag is used, no javascript code is included
in the generated HTML code.</p>

<p>
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>
Own Id: OTP-10025</p>
</item>
<item>
<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>
Own Id: OTP-10049</p>
</item>
<item>
<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 Common Test User's Guide.</p>

<p>
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>
<p>
Own Id: OTP-10087 Aux Id: OTP-9865 </p>

<p>
The test specification syntax has been updated with new
and missing terms, such as 'define', 'verbosity',
'auto_compile', 'stylesheet', 'silent_connections',
'basic_html' and 'release_shell'. See the Test
Specification chapter in the Common Test User's Guide for
details.</p>

<p>
It is now possible to pause execution of a test case, by
calling the ct:break/1/2 function. Execution is resumed
with a call to ct:continue/0/1. Break/continue also works
for test cases executing in parallel. See the ct
reference manual for details.</p>
<p>

It is now possible to send user defined events from a
testcase which will be picked up by the installed event
handler.</p>
<p>
Own Id: OTP-10157</p>
</item>
<item>
<p>
A new start option, release_shell, for ct:run_test/1, has
been added, which makes Common Test release the shell
process after the test suite compilation phase is
finished. For details, see the Running Tests chapter in
the User's Guide.</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>
<p>
Own Id: OTP-9595</p>

<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>

<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>

<p>
The ct:get_status/0 function would cause the calling
process to receive 'DOWN' messages if no tests were
running at the time of the call. This bug has been fixed.</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>

Two or more test cases executing in parallel and printing
to screen at the same time with ct:pal/2/3 or
ct:print/2/3 could write into each other's "slots" and
create a mess of mixed strings. In order to avoid this,
only a single IO message is now ever sent per printout
call.</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>

When starting a test with ct_run and adding a directory
to the code path using -pa or -pz (preceding -erl_args),
Common Test would delete any existing directory in the
code path with the same base name (see
filename:basename/1) as the directory being added. This
has been fixed.</p>

If passing two or more directories with the same base
name (see filename:basename/1) to Common Test with ct_run

<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>

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>

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>

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
events by the old names.</p>

By specifying a user defined function ({M,F,A} or fun) as

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>

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>
<p>
Own Id: OTP-9449</p>

<p>
A new built-in common test hook has been added which
captures error_logger and SASL event and prints them in
the testcase log. To disable this (and any other built-in
hooks) pass 'enable_builtin_hooks false' to common test.</p>
<p>
Own Id: OTP-9543</p>
</item>
<item>
<p>
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>,
and can be read by any installed event handler.</p>

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

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
compiled with ct.hrl included). This error has been

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>

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

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

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

{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>

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

has been changed. N now specifies the absolute number of
executions instead.</p>

doesn't recognize are also ignored (i.e. the same

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

Errors in coverage data collection and analysis were
difficult to detect. The logging has been improved so
that more information about e.g. imported and missing
modules is printed to the html log files.</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>

In previous versions of Common Test, only one FTP
connection could be opened per configuration target name.
This has been updated so that multiple connections may be
opened. The possibility to use named connections is still
supported.</p>

The Erlang mode for Emacs has been updated with new and
modified skeletons for Common Test and TS. Syntax for
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>

The step functionality in Common Test (based on
interaction with Debugger) was broken. This has been
fixed, and some new step features have also been added.

(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>

<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>

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>
