@rbillings Hmm, I'm not sure why this is in the marketing-project-template repo. Should this be in mcom-tests or some other repo? This repo isn't meant for actual tests. It's just a template that can be used by folks who are looking to create a new test suite.

@stephendonner - is there a reason why #5 is in this repo?

@stephendonner ping

Sorry I missed the earlier ping.

1. running as "engagement.template," this was actually used (primarily in the Firefox 4 days) for Marketing/Engagement test-automation -- and it found bugs like missing favicons, bad links, etc. zh-TW should *never* fall-back to zh-CN #5 was specific to Firefox Flicks, which was the latest/last project to really have this suite run against it
2. I still think there's value in some of these tests - both as potential stand-alones in this suite, run against a new site, or copied over in one of our example test-automation repos (e.g. @davehunt 's new one).

Here's the actual locale test that issue #5 was hoping to agument: https://github.com/mozilla/marketing-project-template/blob/master/tests/test_file.py#L32

We should include a docstring to explain the test here. If I understand correctly we want to check that opening [base]/zh_TW should either stay as [base]/zh_TW or become [base]/en-US. If this is the case I would attempt to make this test a little more generic using a list of locales that this could apply to (with just one for now). I would therefore also update the name of the test to reflect this. Something like test_locales_persist_or_fallback_to_en_us.

I think @bobsilverberg was confusing this with the https://github.com/mozilla/mozwebqa-test-templates repository. Even though this suite is not currently being run (since the Jenkins migration) the issue/test seems valid to me.

[bobsilverberg]

I'm just reviewing all open PRs and found this one. I must admit I'm still a bit confused about it, and yes, I guess I was confusing this repo with https://github.com/mozilla/mozwebqa-test-templates.

In any case, there have been a bunch of comments made my @davehunt that are waiting to be addressed. @rbillings are you going to continue with this PR and attempt to address @davehunt's comments?

[rbillings]

I will complete this- it's just low on the totem pole. I'll aim for early June as I doubt I'll get to it this week.

[rbillings]

I updated this, but am unsure how to run the test to verify that it would actually work.

Nit: Standard library imports should be at the top. See http://legacy.python.org/dev/peps/pep-0008/#imports
