<h3>MODULE SUMMARY</h3>
<div class="REFBODY">A framework for automated testing of arbitrary target nodes</div>
<h3>DESCRIPTION</h3>
<div class="REFBODY"><p>
<p>The <strong>Common Test</strong> framework is an environment for
implementing and performing automatic and semi-automatic execution of
test cases.
Common Test uses the OTP Test Server as engine for test case
execution and logging.</p>
<p>In brief, Common Test supports:</p>
<ul>
<li>Automated execution of test suites (sets of test cases).</li>
<li>Logging of the events during execution.</li>
<li>HTML presentation of test suite results.</li>
<li>HTML presentation of test suite code.</li>
<li>Support functions for test suite authors.</li>
<li>Step by step execution of test cases.</li>
</ul>
<p>The following sections describe the mandatory and optional test suite
functions Common Test will call during test execution. For more details
see <span class="bold_code"><a href="write_test_chapter.html">Common Test User's
Guide.</a></span> </p>

<div class="REFBODY"><p>
<p> MANDATORY </p>
<p>This function must return the list of all test cases and test
case groups in the test suite module that are to be executed.
This list also specifies the order the cases and groups will
be executed by Common Test. A test case is represented by an atom,
the name of the test case function. A test case group is
represented by a <span class="code">group</span> tuple, where <span class="code">GroupName</span>,
an atom, is the name of the group (defined in <span class="code"><span class="bold_code"><a href="#Module:groups-0">groups/0</a></span></span>).
Execution properties for groups may also be specified, both
for a top level group and for any of its sub-groups.
Group execution properties specified here, will override
properties in the group definition (see <span class="code"><span class="bold_code"><a href="#Module:groups-0">groups/0</a></span></span>).
(With value <span class="code">default</span>, the group definition properties
will be used).</p>
<p> If <span class="code">{skip,Reason}</span> is returned, all test cases
in the module will be skipped, and the <span class="code">Reason</span> will
be printed on the HTML result page.</p>

<p>This is the test suite info function. It is supposed to
return a list of tagged tuples that specify various properties
related to the execution of this test suite (common for all
test cases in the suite).</p>
<p>The <span class="code">timetrap</span> tag sets the maximum time each
test case is allowed to execute (including <span class="code"><span class="bold_code"><a href="#Module:init_per_testcase-2">init_per_testcase/2</a></span></span>
and <span class="code"><span class="bold_code"><a href="#Module:end_per_testcase-2">end_per_testcase/2</a></span></span>). If the timetrap time is
exceeded, the test case fails with reason
<span class="code">timetrap_timeout</span>. A <span class="code">TimeFunc</span> function can be used to
set a new timetrap by returning a <span class="code">TimeVal</span>. It may also be
used to trigger a timetrap timeout by, at some point, returning a
value other than a <span class="code">TimeVal</span>. (See the
<span class="bold_code"><a href="write_test_chapter.html#timetraps">User's Guide</a></span>
for details).
</p>
<p>The <span class="code">require</span> tag specifies configuration variables
that are required by test cases (and/or configuration functions)
in the suite. If the required configuration variables are not found
in any of the configuration files, all test cases are skipped. For more
information about the 'require' functionality, see the
reference manual for the function
<span class="code"><span class="bold_code"><a href="ct.html#require-1">ct:require/1/2</a></span></span>.</p>
<p>With <span class="code">userdata</span>, it is possible for the user to
specify arbitrary test suite related information which can be
read by calling <span class="code"><span class="bold_code"><a href="ct.html#userdata-2">ct:userdata/2</a></span></span>.</p>
<p>The <span class="code">ct_hooks</span> tag specifies which
<span class="bold_code"><a href="ct_hooks_chapter.html">Common Test Hooks</a></span>
are to be run together with this suite.</p>
<p>Other tuples than the ones defined will simply be ignored.</p>

<p>This configuration function is called as the first function in the
suite. It typically contains initializations which are common for
all test cases in the suite, and which shall only be done
once. The <span class="code">Config</span> parameter is the configuration data
which can be modified here. Whatever is returned from this
function is given as <span class="code">Config</span> to all configuration functions
and test cases in the suite. If <span class="code">{skip,Reason}</span>

<p>This is the test case group info function. It is supposed to
return a list of tagged tuples that specify various properties
related to the execution of a test case group (i.e. its test cases
and sub-groups). Properties set by
<span class="code"><span class="bold_code"><a href="#Module:group-1">group/1</a></span></span> override
properties with the same key that have been previously set by
<span class="code"><span class="bold_code"><a href="#Module:suite-0">suite/0</a></span></span>.</p>
<p>The <span class="code">timetrap</span> tag sets the maximum time each
test case is allowed to execute (including <span class="code"><span class="bold_code"><a href="#Module:init_per_testcase-2">init_per_testcase/2</a></span></span>
and <span class="code"><span class="bold_code"><a href="#Module:end_per_testcase-2">end_per_testcase/2</a></span></span>). If the timetrap time is
exceeded, the test case fails with reason
<span class="code">timetrap_timeout</span>. A <span class="code">TimeFunc</span> function can be used to
set a new timetrap by returning a <span class="code">TimeVal</span>. It may also be
used to trigger a timetrap timeout by, at some point, returning a
value other than a <span class="code">TimeVal</span>. (See the
<span class="bold_code"><a href="write_test_chapter.html#timetraps">User's Guide</a></span>
for details).</p>
<p>The <span class="code">require</span> tag specifies configuration variables
that are required by test cases (and/or configuration functions)
in the suite. If the required configuration variables are not found
in any of the configuration files, all test cases in this group are skipped.
For more information about the 'require' functionality, see the
reference manual for the function
<span class="code"><span class="bold_code"><a href="ct.html#require-1">ct:require/1/2</a></span></span>.</p>
<p>With <span class="code">userdata</span>, it is possible for the user to
specify arbitrary test case group related information which can be
read by calling <span class="code"><span class="bold_code"><a href="ct.html#userdata-2">ct:userdata/2</a></span></span>.</p>
<p>The <span class="code">ct_hooks</span> tag specifies which
<span class="bold_code"><a href="ct_hooks_chapter.html">Common Test Hooks</a></span>
are to be run together with this suite.</p>
<p>Other tuples than the ones defined will simply be ignored.</p>

<p>This configuration function is called before execution of a
test case group. It typically contains initializations which are
common for all test cases and sub-groups in the group, and which
shall only be performed once. <span class="code">GroupName</span> is the name of the
group, as specified in the group definition (see <span class="code"><span class="bold_code"><a href="#Module:groups-0">groups/0</a></span></span>). The
<span class="code">Config</span> parameter is the configuration data which can be modified
here. The return value of this function is given as <span class="code">Config</span>
to all test cases and sub-groups in the group. If <span class="code">{skip,Reason}</span>
is returned, all test cases in the group will be skipped and

<p> MANDATORY </p>
<p>This is the implementation of a test case. Here you must
call the functions you want to test, and do whatever you
need to check the result. If something fails, make sure the
function causes a runtime error, or call <span class="code"><span class="bold_code"><a href="ct.html#fail-1">ct:fail/1/2</a></span></span>
(which also causes the test case process to terminate).</p>
<p>Elements from the <span class="code">Config</span> list can e.g. be read
with <span class="code">proplists:get_value/2</span> (or the macro <span class="code">?config</span>
defined in <span class="code">ct.hrl</span>).</p>
<p>You can return <span class="code">{skip,Reason}</span> if you decide not to
run the test case after all. <span class="code">Reason</span> will then be
printed in 'Comment' field on the HTML result page.</p>
<p>You can return <span class="code">{comment,Comment}</span> if you wish to
print some information in the 'Comment' field on the HTML
result page.</p>
<p>If the function returns anything else, the test case is
considered successful. (The return value always gets printed
in the test case log file).</p>
