1144907 - Marionette's gather_debug shouldn't leave calling code in content scope if it didn't start there

Status: RESOLVED FIXED

(Remote Protocol :: Marionette, defect)

Description

[Chris Manchester (limited bugmail, email directly)]

We can use using_context so callers in chrome scope can be sure their tearDown code runs in the correct scope when a test is skipped or fails.

I'm not familiar with MozReview. I've left a comment. Could you include the Gip tests (gaia-ui-test-accessibility,gaia-ui-test-unit,gaia-ui-test-functional-1,gaia-ui-test-functional-2,gaia-ui-test-functional-3) in your try run?

Can we not combine these into a single using_context?

Hm, how is this related to bug 1141519? David, maybe you can give an answer before Chris comes online later today?

Comment 6

[David Burns :automatedtester]

They are not related. Since we are still using content this patch would still hit the issue that we see in bug 1141519

It seems that getting a screenshot is really intended to work in chrome, and getting the page source is really intended to work in content, so if we don't have using_context for each either callers in chrome or callers in content aren't going to get what they expect.

Try in comment 7 and comment 2. The jobs that failed in comment 7 don't run this code.
