<comsummary>Program used for starting <c>Common Test</c> from the
OS command line.</comsummary>
<description>
<p>The <c>ct_run</c> program is automatically installed with Erlang/OTP
and the <c>Common Test</c> application (for more information, see
section <seealso marker="install_chapter">Installation</seealso>
in the User's Guide). The program accepts different start flags.
Some flags trigger <c>ct_run</c> to start <c>Common Test</c> and
pass on data to it. Some flags start an Erlang node prepared for
running <c>Common Test</c> in a particular mode.</p>
<p>The interface function
<seealso marker="ct#run_test-1"><c>ct:run_test/1</c></seealso>,
corresponding to the <c>ct_run</c> program, is used for starting
<c>Common Test</c> from the Erlang shell (or an Erlang program).
For details, see the <seealso marker="ct"><c>ct</c></seealso>
manual page.</p>
<p><c>ct_run</c> also accepts Erlang emulator flags. These are used
when <c>ct_run</c> calls <c>erl</c> to start the Erlang node (this
makes it possible to add directories to the code server path,
change the cookie on the node, start more applications, and so on).</p>
<p>With the optional flag <c>-erl_args</c>, options on the <c>ct_run</c>
command line can be divided into two groups:</p>
<list type="bulleted">
<item>One group that <c>Common Test</c> is to process (those
preceding <c>-erl_args</c>).</item>
<item>One group that <c>Common Test</c> is to ignore and pass on
directly to the emulator (those following <c>-erl_args</c>).</item>
</list>
<p>Options preceding <c>-erl_args</c> that <c>Common Test</c>
does not recognize are also passed on to the emulator untouched.
By <c>-erl_args</c> the user can specify flags with the same name, but
with different destinations, on the <c>ct_run</c> command line.</p>
<p>If flags <c>-pa</c> or <c>-pz</c> are specified in the
<c>Common Test</c> group of options (preceding <c>-erl_args</c>),
relative directories are converted to absolute and reinserted into
the code path by <c>Common Test</c>. This is to avoid problems
loading user modules when <c>Common Test</c> changes working directory
during test runs. However, <c>Common Test</c> ignores flags <c>-pa</c>
and <c>-pz</c> following <c>-erl_args</c> on the command line. These
directories are added to the code path normally (that is, on specified
form).</p>
<p>Exit status is set before the program ends. Value <c>0</c> indicates
a successful test result, <c>1</c> indicates one or more failed or
auto-skipped test cases, and <c>2</c> indicates test execution failure.</p>
<p>If <c>ct_run</c> is called with option <c>-help</c>, it prints all
valid start flags to <c>stdout</c>.</p>
