+ TEST_QEMUBOOT_TIMEOUT
+
+
+ The time in seconds allowed for a QEMU image to boot before
+ tests begin to run against the image using the following
+ command:
+
+ bitbake <qemu_image> -c testimage
+
+
+
+
+ The default timeout period to allow the boot process to
+ reach the login prompt is 500 seconds.
+ You can edit this default value in the
+ local.conf file.
+
+
+
+ For more information on testing QEMU images, see the
+ "Running and Writing Tests for a QEMU Image"
+ section in the Yocto Project Development Manual.

+
+ TEST_SUITES
+
+
+ An ordered list of tests (modules) to run against
+ a QEMU image using the following command:
+
+ bitbake <qemu_image> -c testimage
+
+
+
+
+ The Yocto Project provides a core set of tests that can
+ be used against QEMU images.
+ Tests include ping,
+ ssh, df among
+ others.
+ You can add your own tests to the list of tests by
+ appending TEST_SUITES as follows:
+
+ TEST_SUITES_append = " mytest"
+
+
+
+
+ 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 (test_A and
+ test_B) where
+ test_B is dependent on
+ test_A, then you must order the tests
+ as follows:
+
+ TEST_SUITES = " test_A test_B"
+
+
+
+
+ For more information on testing QEMU images, see the
+ "Running and Writing Tests for a QEMU Image"
+ section in the Yocto Project Development Manual.
