Hm, I should've been more clear. This isn't what I meant, either. I'm instead
wondering about the feasibility of implementing this as a ScriptTest that gets
specified in src/testing/buildbot/chromium.fyi.json.

After talking with Yoland it seems like making it a script test isnt the best
idea. This needs to upload some things to Google Storage and clean up temp files
after the script runs. Moving these things into a script would duplicate code
(we already have recipe APIs to do these things) and just make it more complex.

eh, _TEST_APKS probably. or _DEFAULT_TEST_APKS

How does your script find the test apks? Should you be passing the fullpaths to
the apks to this script?

+              '--json-output-dir', temp_output_dir,

+    finally:
+      api.file.rmtree('Delete temp out directory', temp_output_dir)

[Paweł Hajdan Jr., 2016/07/04 10:42:42]

Could you use tempfile.temp_dir context manager from the recipe engine?
