<p>Distributed test execution control for <c>Common Test</c>.</p>
<p>This module exports functions for running <c>Common Test</c> nodes on
multiple hosts in parallel.</p>
</description>
<funcs>
<func>
<name>abort() -> ok</name>
<fsummary>Stops all running tests.</fsummary>
<desc><marker id="abort-0"/>
<p>Stops all running tests.</p>
</desc>
</func>
<func>
<name>abort(Nodes) -> ok</name>
<fsummary>Stops tests on specified nodes.</fsummary>
<type>
<v>Nodes = atom() | [atom()]</v>
</type>
<desc><marker id="abort-1"/>
<p>Stops tests on specified nodes.</p>
</desc>
</func>
<func>
<name>basic_html(Bool) -> ok</name>
<fsummary>If set to true, the ct_master logs are written on a primitive
HTML format, not using the <c>Common Test</c> CSS style sheet.</fsummary>
<type>
<v>Bool = true | false</v>
</type>
<desc><marker id="basic_html-1"/>
<p>If set to <c>true</c>, the <c>ct_master logs</c> are written on a
primitive HTML format, not using the <c>Common Test</c> CSS style
sheet.</p>
</desc>
</func>
<func>
<name>get_event_mgr_ref() -> MasterEvMgrRef</name>
<fsummary>Gets a reference to the <c>Common Test</c> master event
manager.</fsummary>
<type>
<v>MasterEvMgrRef = atom()</v>
</type>
<desc><marker id="get_event_mgr_ref-0"/>
<p>Gets a reference to the <c>Common Test</c> master event manager.
The reference can be used to, for example, add a user-specific
event handler while tests are running.</p>
<p><em>Example:</em></p>
<pre>
gen_event:add_handler(ct_master:get_event_mgr_ref(), my_ev_h, [])</pre>
</desc>
</func>
<func>
<name>progress() -> [{Node, Status}]</name>
<fsummary>Returns test progress.</fsummary>
<type>
<v>Node = atom()</v>
<v>Status = finished_ok | ongoing | aborted | {error, Reason}</v>
<v>Reason = term()</v>
</type>
<desc><marker id="progress-0"/>
<p>Returns test progress. If <c>Status</c> is <c>ongoing</c>, tests
are running on the node and are not yet finished.</p>

<p>Tests are spawned on the nodes as specified in <c>TestSpecs</c>.
Each specification in <c>TestSpec</c> is handled separately.
However, it is also possible to specify a list of specifications to
be merged into one specification before the tests are executed. Any
test without a particular node specification is also executed on
the nodes in <c>InclNodes</c>. Nodes in the <c>ExclNodes</c> list
are excluded from the test.</p>
