Debugging tests ================
You can use the TEST_FILTER environment variable, e.g., TEST_FILTER=xxx
will filter test named test_xxx.
Setting TEST_GECKODRIVER_TRACE to any value will make Selenium dump a trace
log for debugging.
You can control running headless or not with TEST_NO_HEADLESS. Currently,
the copy/paste image test required NOT to run headless.
More useful for local repro, you can set TEST_NO_QUIT if you need to keep
inspecting the browser at the end of a test.
Data URL containing the diff screenshot will be dumped to stdout/stderr when
TEST_DUMP_DIFF is set in the environment.
A recording of the desktop can be captured via GNOME Screencast feature by
passing TEST_RECORD_SCREEN=true in the enviromnent. Upon completion of the
task it should upload a WebM file.
