	    A new variant of the <c>newline</c> option to
	    <c>ct_telnet:cmd/3</c> and <c>ct_telnet:send/3</c> is
	    added, which allows to specify a string to append as

	    "\n", but in some cases it is required to be "\r\n",
	    which this option allows.</p>
          <p>
	    A faulty regular expression given as parameter to

	    indication is now given, but the test case will still

	    The Logger handler cth_log_redirect earlier called the
	    report callback (report_cb) before calling the logger
	    formatter. In some cases this would fail, since
	    cth_log_redirect could not handle report callbacks with
	    two arguments. This is now corrected, so only the
	    formatter will call the report callback.</p>

	    <p>The following corrections and improvements are done in
	    the common_test hook handling:</p> <list> <item> <p>An
	    extra argument, <c>Suite</c>, is added as the first
	    argument to each of the following hook callback
	    functions:</p> <list>
	    <item><c>pre_init_per_group</c></item>
	    <item><c>post_init_per_group</c></item>

	    <item><c>on_tc_fail</c></item>
	    <item><c>on_tc_skip</c></item> </list> <p>For backwards
	    compatibility, if the new function is not exported from a
	    hook callback module, <c>common_test</c> will fall back
	    to the old interface and call the function without the
	    <c>Suite</c> argument.</p> </item> <item> <p>If either
	    <c>init_per_suite</c> or <c>end_per_suite</c> exists, but
	    not the other, then the non-existing function will be
	    reported as failed with reason <c>undef</c> in the test
	    log. The same goes for <c>init/end_per_group</c>. This
	    has always been a requirement according to the user's
	    guide, but now <c>common_test</c> is more explicit in the
	    report.</p> </item> <item> <p>If <c>init_per_suite</c>
	    was exported from a test suite, but not
	    <c>end_per_suite</c>, then <c>pre/post_end_per_suite</c>
	    was called with <c>Suite=ct_framework</c> instead of the
	    correct suite name. This is now corrected.</p> </item>
	    <item> <p>If <c>end_per_group</c> was exported from a
	    suite, but not <c>init_per_group</c>, then
	    <c>end_per_group</c> was never called. This is now
	    corrected.</p> </item> <item> <p>Tests that were skipped
	    before calling <c>pre_init_per_*</c> got faulty calls to
	    the corresponding <c>post_init_per_*</c>. E.g. if a test
	    was skipped because <c>suite/0</c> failed, then
	    <c>post_init_per_suite</c> would be called even though
	    <c>pre_init_per_suite</c> and <c>init_per_suite</c> were
	    not called. This is now corrected so a <c>post_*</c>
	    callback will never be called unless the corresponding
	    <c>pre_*</c> callback has been called first.</p> </item>
	    <item> <p>Tests that were skipped before or in
	    <c>init_per_testcase</c> got faulty calls to
	    <c>pre_end_per_testcase</c> and
	    <c>post_end_per_testcase</c>. This is now corrected so
	    <c>pre/post_end_per_testcase</c> are not called when
	    <c>end_per_testcase</c> is not called.</p> </item> <item>
	    <p>If an exit signal causes the test case process to die
	    while running <c>init_per_testcase</c>, the case was
	    earlier reported as failed with reason <c>{skip,...}</c>.
	    This is now corrected so the case will be marked as
	    skipped.</p> </item> <item> <p>If an exist signal causes
	    the test case process to die while running
	    <c>end_per_testcase</c>, the case was earlier marked as
	    failed. This is now corrected so the status of the test
	    case is not changed - there is only a warning added to
	    the comment field.</p> </item> <item> <p>If a test case
	    was skipped because of option
	    <c>{force_stop,skip_rest}</c> or because of a failed
	    sequence, then no <c>tc_start</c> event would be sent,
	    only <c>tc_done</c>. This is now corrected so both events
	    are sent.</p> </item> <item> <p>When skipping or failing
	    in a configuration function, the configuration function
	    itself would get <c>{auto_skipped,Reason}</c>,
	    <c>{skipped,Reason}</c> or <c>{failed,Reason}</c> in the
	    hook callbacks <c>on_tc_skip</c> or <c>on_tc_fail</c>.
	    The other test cases that were skipped as a result of
	    this would only get <c>Reason</c> in <c>on_tc_skip</c>.
	    This is now corrected so even the configuration function
	    that caused the skip/fail will only get <c>Reason</c> in
	    the hook callback.</p> </item> </list>

	    Some types of printouts to screen during test runs

	    The <c>nodelay</c> option used to be enabled
	    (<c>true</c>) by default for sockets opened by the Common
	    Test telnet client. This appeared to cause communication
	    problems with telnet servers on some systems, and
	    therefore the option is no longer used. Its value may
	    instead be specified in the telnet connection settings.
	    See the man page for <c>ct_telnet</c> for details. Please

	    Printouts made with <c>io:format/2</c> and

	    automatically. Common Test will not attempt to escape
	    characters printed with <c>ct:log/2</c> since it is
	    assumed that the user may want to print html tagged data
	    using this function. A new function, <c>ct:log/5</c>, has
	    been added, which offers optional escaping of characters.
	    The latter function may also be used to print text to the
	    log without headers and CSS class wrapping (analogue to
	    <c>io:format/2</c>).</p>

	    In ct_netconfc, if a timer expired 'at the same time' as

	    already be in the client's message queue when the client
	    removed the timer ref from its 'pending' list. This

	    When a test case (or configuration function) fails
	    because of an exit signal from a linked process, Common
	    Test previously passed only the reason for process
	    termination to the CT post hook functions and the event
	    handlers (in the tc_done event). This has been changed so
	    that now the tuple {'EXIT',ReasonForProcessTermination}
	    is passed instead. This makes it much easier in the CT
	    post hook functions to distinguish a failure of this sort
	    from other types of errors and from the return value of a
	    successful test case.</p>

	    config values, which are documented in the ct_telnet
	    reference manual. The polling mechanism is disabled by
	    default (making the get_data/1 function backwards

	    The common_test telnet client, ct_telnet and friends, had
	    some unstable test cases. Some of these were caused by
	    the unix_telnet callback sending an extra newline after
	    sending the password. This caused the sever to send an
	    extra prompt back which confused the tests. The extra
	    newline is no longer sent.</p>

	    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.</p>
          <p>
	    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.</p>
          <p>
	    The repeated compilation and analysis of the same modules
	    was also very time consuming.</p>
          <p>
	    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.</p>

	    <p>The way Common Test handles skipping of test cases has
	    been updated. In previous versions, returning
	    <c>{skip,Reason}</c> from a configuration function (such
	    as init_per_suite or init_per_group), resulted in all
	    affected test cases getting skipped with status
	    <c>auto_skipped</c>. 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 <c>user_skipped</c>
	    instead.</p> <p>This update has meant a few changes that
	    may affect Common Test users in various ways:</p> <list>

	    down the connection) if the close-session request times

	    opening a new connection with the same name would make
	    common_test try to reuse the same connection since it
	    believed that it was still alive. This has been corrected

	    Integrate elliptic curve contribution from Andreas

          <p>
	    In order to be able to support elliptic curve cipher
	    suites in SSL/TLS, additions to handle elliptic curve
	    infrastructure has been added to public_key and crypto.</p>
          <p>
	    This also has resulted in a rewrite of the crypto API to
	    gain consistency and remove unnecessary overhead. All OTP
	    applications using crypto has been updated to use the new
	    API.</p>
          <p>
	    Impact: Elliptic curve cryptography (ECC) offers
	    equivalent security with smaller key sizes than other
	    public key algorithms. Smaller key sizes result in
	    savings for power, memory, bandwidth, and computational
	    cost that make ECC especially attractive for constrained

	    <p>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:</p>
	    <p>* 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.</p>
	    <p>* 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 <c>badarg</c> exception.</p>
	    <p>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.</p>
	    <p>Also, a new <c>unexpected_io.log</c> 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).</p>

	    <p>It is now possible to let a test specification include
	    other test specifications. Included specs can either be
	    joined with the source spec (and all other joined specs),
	    resulting in one single test run, or they can be executed
	    in separate test runs. Also, a start flag/option,
	    <c>join_specs</c>, has been introduced, to be used in
	    combination with the <c>spec</c> option. With
	    <c>join_specs</c>, Common Test can be told to either join
	    multiple test specifications, or run them separately.
	    Without <c>join_specs</c>, the latter behaviour is
	    default. Note that this is a change compared to earlier
	    versions of Common Test, where specifications could only
	    be joined. More information can be found in the Running
	    Tests chapter in the User's Guide (see the Test
	    Specifications section).</p>

	    The following corrections/changes are done in the
	    cth_surefire hook:</p>
	    <list> <item> Earlier there would always be a
	    'properties' element under the 'testsuites' element. This
	    would exist even if there were no 'property' element
	    inside it. This has been changed so if there are no
	    'property' elements to display, then there will not be a
	    'properties' element either. </item> <item> The XML file
	    will now (unless other is specified) be stored in the top
	    log directory. Earlier, the default directory would be
	    the current working directory for the erlang node, which
	    would mostly, but not always, be the top log directory.
	    </item> <item> The 'hostname' attribute in the
	    'testsuite' element would earlier never have the correct
	    value. This has been corrected. </item> <item> The
	    'errors' attribute in the 'testsuite' element would
	    earlier display the number of failed testcases. This has
	    been changed and will now always have the value 0, while
	    the 'failures' attribute will show the number of failed
	    testcases. </item> <item> A new attribute 'skipped' is
	    added to the 'testsuite' element. This will display the
	    number of skipped testcases. These would earlier be
	    included in the number of failed test cases. </item>
	    <item> The total number of tests displayed by the 'tests'
	    attribute in the 'testsuite' element would earlier
	    include init/end_per_suite and init/end_per_group. This
	    is no longer the case. The 'tests' attribute will now
	    only count "real" test cases. </item> <item> Earlier,
	    auto skipped test cases would have no value in the 'log'
	    attribute. This is now corrected. </item> <item> A new
	    attributes 'log' is added to the 'testsuite' element.
	    </item> <item> A new option named 'url_base' is added for
	    this hook. If this option is used, a new attribute named
	    'url' will be added to the 'testcase' and 'testsuite'
	    elements. </item> </list>

	    A new test case group search functionality has been

	    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

	    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>

	    <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>

	    <c>init/end_per_group(GroupName,Config)</c> it's

	    cannot be used with <c>init/end_per_testcase(TestCase,

	    having to declare copies of the group in question. Also,

	    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.</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

	    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>

	    case termination by returning {fail,Reason}, nor will it

	    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
	    unix_telnet manual pages for details.</p>

	    tc_auto_skip has been modified to make pattern matching
	    on the data easier and more consistent. Also the order in

	    tc_done for the failed configuration function (not
	    before) which makes more sense. Note that no new events

	    "&lt;testobject&gt;_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>

	    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

            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

            return all matching values for the variable. The order of

            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>
