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}.

ct_netconfc:close_session sometimes returned {error,closed} or (if the connection was named) {error,{process_down,Pid,normal}} 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 situation.

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.

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.
Own Id: OTP-10069
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.

The documentation has been updated with information about how to deal with chaining of hooks which return fail/skip.
Own Id: OTP-10077 Aux Id: seq12048
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.

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.
Own Id: OTP-9896 Aux Id: seq12034, OTP-9835
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.
Own Id: OTP-10025
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.
Own Id: OTP-10049
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.
Own Id: OTP-10067 Aux Id: seq12050
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.
Own Id: OTP-10087 Aux Id: OTP-9865
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.
Own Id: OTP-10089 Aux Id: OTP-10049
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.

It is now possible to send user defined events from a testcase which will be picked up by the installed event handler.
Own Id: OTP-10157
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.
Own Id: OTP-10248 Aux Id: OTP-10127
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.
Own Id: OTP-9595
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).
Own Id: OTP-9634 Aux Id: seq11924
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.
Own Id: OTP-9666
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.
Own Id: OTP-9830 Aux Id: seq11975
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.

A link to the ct_run program is now created, as expected, in the installation bin directory (default /usr/local/bin) during 'make install'.
Own Id: OTP-9898
Using the repeat, duration or until option with ct:run_test/1, would cause an infinite loop. This has been fixed.
Own Id: OTP-9899
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.

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.

The wrong exit location was printed in the log file when ct:fail/1 or ct_fail/2 was called.
Own Id: OTP-9933 Aux Id: seq12002
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.
Own Id: OTP-9941 Aux Id: seq12009
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.
Own Id: OTP-9958 Aux Id: OTP-9855
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.
Own Id: OTP-9964
If passing two or more directories with the same base name (see filename:basename/1) to Common Test with ct_run -pa, only one of the directories would actually be added.
Own Id: OTP-9975 Aux Id: seq12019
Configuration data required by the group info function was deleted before the call to post_end_per_group, which made it impossible for the hook function to read and use the data in question. This has been fixed.

Various typographical errors corrected in documentation for common_test, driver, erl_driver and windows installation instructions. (Thanks to Tuncer Ayaz)
Own Id: OTP-10037
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.

A column for test case group name has been added to the suite overview HTML log file.
Own Id: OTP-9730 Aux Id: seq11952
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.
Own Id: OTP-9855 Aux Id: seq11979
The pre- and post CT hook functions are now always called for all configuration functions, even for configuration functions that are not implemented in the test suite.
Own Id: OTP-9880 Aux Id: seq11993
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.
Own Id: OTP-9904 Aux Id: seq11985, OTP-9900
Test Server has been modified to check the SASL errlog_type parameter when receiving an error logger event, so that it doesn't print reports of type that the user has disabled.

The Common Test Master has been updated to use a CSS style sheet for the html log files.
Own Id: OTP-9973
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.

By specifying a user defined function ({M,F,A} or fun) as timetrap value, either by means of an info function or by calling ct:timetrap/1, it is now possible to set a timetrap that will be triggered when the user function returns.
Own Id: OTP-9988 Aux Id: OTP-9501, seq11894
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.

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.

A bug has been fixed that made Test Server call the end_tc/3 framework function with an incorrect module name as first argument.
Own Id: OTP-9379 Aux Id: seq11863
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.
Own Id: OTP-9398
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).

Add a proplist() type
Recently I was adding specs to an API and found that there is no canonical proplist() type defined. (Thanks to Ryan Zezeski)
Own Id: OTP-9499
It is now possible to use the 'step' flag/option to run the debugger for test suites that contain test case groups. This previously caused Common Test to crash. If 'step config' is specified, breakpoints are now also automatically set on init_per_group and end_per_group. Note that breakpoints are always set automatically on test case functions and this is true also for grouped cases.

The dir and suite start option can now be used in combination. E.g. executing my_SUITE in directory my_tests can either be specified as "ct_run -suite my_tests/my_SUITE" or as "ct_run -dir my_tests -suite my_SUITE". Furthermore, the specification: ct:run_test([{suite,["./my_SUITE"]},{testcase,t1}]) is now interpreted as ct:run_test([{suite,"./my_SUITE"},{testcase,t1}]), i.e. only testcase t1 in test suite my_SUITE - not all cases - will be executed.
Own Id: OTP-9155
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).

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).

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.
Own Id: OTP-8485
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.
Own Id: OTP-8490 Aux Id: seq11500
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}.

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.

The run_test script has been replaced by a program (with the same name) which can be executed without explicit installation. The start flags are the same as for the legacy start script.

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.

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).
Own Id: OTP-8690 Aux Id: OTP-8650
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.

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.
Own Id: OTP-8693
A new run_test start option, event_handler_init, has been added that takes a start argument which gets passed to the init function of the event handler.

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.

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.
- The arity calculation is updated.
- 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".
- Enhanced the menu positioning in the html documentation when a new page is loaded.
- A number of corrections in the generation of man pages (thanks to Sergei Golovan)
- The legal notice is taken from the xml book file so OTP's build process can be used for non OTP applications.

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.

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.

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).

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.

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.

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'.

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.

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).

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.

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.

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.
Own Id: OTP-7781
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.
Own Id: OTP-7782
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.

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.
