From: Abdellatif El Khlifi <[email protected]> This commit provides a testcase for the initramfs bundle support implemented in kernel-fitimage.bbclass
The testcase verifies the content of the initramfs bundle node in the FIT Image Tree Source (its). The testcase is self-contained and the configurations are set by the test case itself. To verify the initramfs bundle support, the testcase uses beaglebone-yocto machine. This testcase can be run through the following command: oe-selftest -r fitimage.FitImageTests.test_initramfs_bundle Change-Id: I8ab8abf2c150ea515fd439784eb20c6b092bfbc5 Signed-off-by: Abdellatif El Khlifi <[email protected]> --- meta/lib/oeqa/selftest/cases/fitimage.py | 132 +++++++++++++++++++++++ 1 file changed, 132 insertions(+) diff --git a/meta/lib/oeqa/selftest/cases/fitimage.py b/meta/lib/oeqa/selftest/cases/fitimage.py index 19b9f53ee4..0958036a6f 100644 --- a/meta/lib/oeqa/selftest/cases/fitimage.py +++ b/meta/lib/oeqa/selftest/cases/fitimage.py @@ -231,3 +231,135 @@ UBOOT_MKIMAGE_SIGN_ARGS = "-c 'a smart comment'" result = runCmd('grep "### uboot-mkimage signing wrapper message" %s/log.do_assemble_fitimage' % tempdir, ignore_status=True) self.assertEqual(result.status, 0, 'UBOOT_MKIMAGE_SIGN did not work') + def test_initramfs_bundle(self): + """ + Summary: Verifies the content of the initramfs bundle node in the FIT Image Tree Source (its) + The FIT settings are set by the test case. + The machine used is beaglebone-yocto. + Expected: 1.
