+                    command:

+                    The default timeout period to allow the boot process to

+                    You can edit this default value in the

+                    An ordered list of tests (modules) to run against
+                    a QEMU image using the following command:
+                    <literallayout class='monospaced'>
+     bitbake &lt;qemu_image&gt; -c testimage

+                    The Yocto Project provides a core set of tests that can
+                    be used against QEMU images.
+                    Tests include <filename>ping</filename>,
+                    <filename>ssh</filename>, <filename>df</filename> among
+                    others.
+                    You can add your own tests to the list of tests by
+                    appending <filename>TEST_SUITES</filename> as follows:
+                    <literallayout class='monospaced'>
+     TEST_SUITES_append = " mytest"
+                    </literallayout>
+                </para>

+                    The order in which tests are run is important.
+                    Tests that depend on another test must appear later in the
+                    list than the test on which they depend.
+                    For example, if you append the list of tests with two
+                    tests (<filename>test_A</filename> and
+                    <filename>test_B</filename>) where
+                    <filename>test_B</filename> is dependent on
+                    <filename>test_A</filename>, then you must order the tests
+                    as follows:
+                    <literallayout class='monospaced'>
+     TEST_SUITES = " test_A test_B"
+                    </literallayout>
+                </para>
