Although the tests were initially written for checking the validity of
the text images, it doesn't hurt to run them continuously as part of the
component test (recovery_manual_test requires reboots during the run,
due to the nature of the tests of recovery-{refresh,persist}). This also
allows detecting breaking changes to libminui or libpng.
There's a catch that the ResourcesTest won't be triggered via `atest`,
as the res-* testdata won't be picked up via AndroidTest.xml. Explored
a few options but not addressing that in this CL:
- `atest` is not fully working in AOSP yet (missing support in
tools/tradefederation/core/atest/atest.py).
- `atest` doesn't allow specifying the testdata with path in the 'push'
option.
- It won't fail the test run though, as ResourcesTest will skip the
tests automatically when it finds no text image file.
- APCT and manual `adb sync data` are not affected, and I don't see an
active user of `atest` other than a tool for manual test invocation.
- Unrelated to this CL, `atest` doesn't seem to work well with
recovery_component_test or recovery_unit_test while we have both of
them in one AndroidTest.xml. It randomly triggers only one of them,
despite of the given test name. When splitting AndroidTest.xml into
two, it tends to pick up the wrong testdata subdir and gives wrong
results.
Test: Run recovery_manual_test and recovery_component_test on marlin.
