Patch 1/2 of this series provides basic testing of the get_test_result functionality. This Patch adds further testing of possible error scenarios, but relies on rebooting sandbox at the beginning of the test.
Signed-off-by: Julia Daxenberger julia.daxenberger@infineon.com --- Changes in v2: - Add error test cases reliant on restart_uboot() in response to Simon Glass sjg@chromium.org
