The status of an aborted test due to test suite compilation error has changed from 'auto_skipped' to 'failed'. This affects both the textual log file, event handling and CT hook callbacks. The logging of compilation failures has also been improved, especially in the case of multiple test suites failing compilation.

When running OTP tests using the ts interface, it is now possible to specify so called test categories per OTP application. A test category is represented by a CT test specification and defines an arbitrary subset of existing test suites, groups and cases. Examples of test categories are 'smoke' (smoke tests) and 'bench' (benchmarks). (Call ts:help() for more info). Also, functions for reading terms from the current test specification during test, ct:get_testspec_terms/0 and ct:get_testspec_terms/1, have been implemented.

If the last expression in a test case causes a timetrap timeout, the stack trace is ignored and not printed to the test case log file. This happens because the {Suite,TestCase,Line} info is not available in the stack trace in this scenario, due to tail call elimination. Common Test has been modified to handle this situation by inserting a {Suite,TestCase,last_expr} tuple in the correct place and printing the stack trace as expected.

When installing test suites in a cross compilation environment, ts_install was not able to read the values of the environment variables specified in the configuration file. This has been fixed.

Printouts by means of ct:log/2/3 or ct:pal/2/3 from the hook functions on_tc_fail/2 and on_tc_skip/2 would (quite unexpectedly) end up in the "unexpected i/o" log file instead of in the test case log file. This behaviour has been changed so that now, all printouts (including stdio printouts) from these hook functions will be routed to the test case log file.

The format of the information printed on top of the test case (and configuration function) log file has been slightly modified, mainly in order to make the start configuration data easier to read and interpret.

The source code to html code generator in Test Server (and Common Test) would fail to generate anchors in the html code for functions with non-expandable macros, resulting in bad html links to such functions. This correction lets the code generator ignore macros that can't be expanded (i.e. not pre-process them), so that correct anchors will always be produced.

The mechanism for running code cover analysis with common_test has been improved. Earlier, if a test run consisted of multiple tests, cover would be started and stopped for each test. This would give "intermediate" cover logs available from the "Coverage log" link on the test suite result pages. To accumulate cover data over all tests, the 'export' option had to be used in the cover spec file. This was not well documented, and the functionality was quite confusing.

Using the 'nodes' option in the cover spec file would fail when the test run consisted of multiple tests, since the specified nodes would only be included in the cover analysis of the first test.

The repeated compilation and analysis of the same modules was also very time consuming.

To overcome these problems, ct will now only cover compile and analyze modules once per test run, i.e. once for each cover spec file. The log file is available via a new button on the top level index page. The old "Coverage log" links on the test suite result pages still exist, but they all point to the same log containing the accumulated result.

The way Common Test handles skipping of test cases has been updated. In previous versions, returning {skip,Reason} from a configuration function (such as init_per_suite or init_per_group), resulted in all affected test cases getting skipped with status auto_skipped. This was inappropriate, since this status is supposed to be used to inform that Common Test has taken the initiative to skip something (e.g. a test case group if init_per_group failed). Therefore, in this version of Common Test, whenever the user skips a suite, group, or individual test case (by means of a configuration function or test specification term), the affected test cases get the status user_skipped instead.

This update has meant a few changes that may affect Common Test users in various ways: The test results and statistics will be affected, which is important to know when running regression tests and comparing results to previous test runs. Users that read or parse the textual log file suite.log will notice that an auto skipped function is now reported as auto_skipped rather than skipped as before. When require fails in an info function (such as suite/0 or group/1), all affected configuration functions and test cases are marked as auto_skipped. If Common Test detects an error in the test suite (such as e.g. an invalid all/0 function), all affected configuration functions and test cases are marked as auto_skipped. If a repeated test run session reaches a deadline with force_stop enabled, all remaining test cases are marked as auto_skipped rather than user_skipped as before. The event messages that Common Test generates during test runs have been affected by this update. For details see OTP-11524.

Test Server installed an error handler (test_server_h) only to be able to write the name of the current test case to stdout whenever it received an error- or progress report. This functionality was not useful and has been removed. The built-in Common Test hook, cth_log_redirect, has instead been improved to now also tag all error- and progress reports in the log with suite-, group-, and/or test case name.

A new log, the "Pre- and Post Test I/O Log", has been introduced, which makes it possible to capture error- and progress reports, as well as printouts made with ct:log/2 and ct:pal/2, before and after a test run. (Some minor improvements of the logging system have been made at the same time). Links to the new log are found on the Common Test Framework Log page. The Common Test User's Guide has been updated with information about the new log and also with a new section on how to synchronize external applications with Common Test by means of the CT Hook init and terminate functions.

The unicode update of test_server for R16A introduced a few potential errors when logging to files. Sometimes ~tp or ~ts was used for formatting also when writing to files that were not opened with the {encoding,utf8} option. If then the argument contained unicode characters above 255, the file descriptor would crash. This has been corrected by the following modifications: Since the 'unexpected_io' log file is used only when the test case HTML file is not available (e.g. between test cases), this file is now also a HTML file and as other test_server HTML logs it is always UTF-8 encoded Since it is possible to change which information is going to which log file (with test_server_ctrl:set_levels/3), we do not have full control over which information is written to which file. This means that any printout could be written to the 'major' log file (suite.log), which was earlier encoded as latin1. To avoid crashing this file descriptor due to unicode strings, the 'major' log file is now also encoded in UTF-8 (possible incopatibility). The cross_cover.info file is no longer a text file which can be read with file:consult/1, instead it is written as a pure binary file using term_to_binary when writing and binary_to_term when reading. The encoding of the file named 'last_name', which only content is the path to the last run.<timestamp> directory, is now dependent on the file name mode of the VM. If file names are expected to be unicode, then the 'last_name' file is UTF-8 encoded, else it is latin1 encoded.

Also, ~tp has been changed back to ~p unless it is somehow likely that the argument includes strings. It is not obvious that this is the correct thing to do, but some decission had to be taken...

Any call to test_server:break/1 should cancel all active timetramps. However, in some cases Suite:end_per_testcase/2 is executed on a different process than the test case itself, and if test_server:break/1 was called from there, the timetraps were not cancelled. This has been corrected.

In test_server, the same process would supervise the currently running test case and be group leader (and IO server) for the test case. Furthermore, when running parallel test cases, new temporary supervisor/group leader processes were spawned and the process that was group leader for sequential test cases would not be active. That would lead to several problems:

* Processes started by init_per_suite will inherit the group leader of the init_per_suite process (and that group leader would not process IO requests when parallel test cases was running). If later a parallel test case caused such a processto print using (for example) io:format/2, the calling would hang.

* Similarly, if a process was spawned from a parallel test case, it would inherit the temporary group leader for that parallel test case. If that spawned process later - when the group of parallel tests have finished - attempted to print something, its group leader would be dead and there would be badarg exception.

Those problems have been solved by having group leaders separate from the processes that supervises the test cases, and keeping temporary group leader process for parallel test cases alive until no more process in the system use them as group leaders.

Also, a new unexpected_io.log log file (reachable from the summary page of each test suite) has been introduced. All unexpected IO will be printed into it(for example, IO to a group leader for a parallel test case that has finished).

Update common test modules to handle unicode Use UTF-8 encoding for all HTML files, except the HTML version of the test suite generated with erl2html2:convert, which will have the same encoding as the original test suite (.erl) file.

Use unicode:characters_to_list and unicode:characters_to_binary for conversion between binaries and strings instead of binary_to_list and list_to_binary.

test_server_h will now recognize info_reports written by ct connection handlers (according to the description in cth_conn_log) and ignore them as they will be completely handled by by ct_conn_log_h.

Earlier test_server_h would print a tag (testcase name) before forwarding the report to error_logger_tty_h. This would cause lots of tags in the log with no info report following (since error_logger_tty_h did not handle them).

After a test case timeout or abortion, the end_per_testcase function executes on a new dedicated process.

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.

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.

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'.

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.
