<refname>Tests for target startup monitoring</refname>
<refpurpose>
How to verify that the target startup monitoring functionality of the
NSC correctly identifies targets have started, and sets the node state
accordingly via the NSM.
</refpurpose>
</refnamediv>
<refsect1>
<title>Test environment and setup</title>
<refsect2>
<title>Target units</title>
<para>
This testing requires the existence of focussed.target, unfocussed.target and
lazy.target units.
If they do not exist, they can be created by executing the following:
<programlisting>cp /lib/systemd/system/{graphical,focussed}.target
cp /lib/systemd/system/{graphical,unfocussed}.target
cp /lib/systemd/system/{graphical,lazy}.target</programlisting>
</para>
</refsect2>
</refsect1>
<refsect1>
<title>Test cases</title>
<note>
The node state is defined by the <link linkend="NSMNodeState">NSMNodeState</link>
enumeration. When the node state is set, the DLT log refers to it by its number.
</note>
<para>
The following test cases for Target Startup Monitoring are described in this document:
