[test] api/endpoints.py needs more tests coverage

[karlcow]

https://github.com/webcompat/webcompat.com/blob/136607eeb2ff0c65ee681ad942875937a920cb9b/webcompat/api/endpoints.py#L30

The API is only partially tested currently. (69% as of today) and would benefit of a better coverage.

[karlcow]

since 2016, the code has a blueprint for errors which is… not used. https://github.com/webcompat/webcompat.com/commit/44e804ff3d99ed389c996c4f745049717dbbff3c

[miketaylr]

Unused means no errors caused by this code, right???

[karlcow]

@miketaylr I don't think any current views are returning something because of this blueprint, or said in anothe way, it seems we could delete it without any impact, I haven't tried it yet.

[miketaylr]

Are we sure this isn't actually used? AFAICT, this is the only thing controlling the error messages that we do see (like Not Found. Lost in Punk Cat Space). => https://webcompat.com/tacos

[karlcow]

ah right then it's used! And it's magical and I need to double check something. Thanks for digging this.

This is working indeed! Cool.

}

That will simplify my tests reasoning and removes one modification I did yesterday. My test was bad.

[karlcow]

one thing i like about the combination of pytest and coverage is that it really shows what is not tested.

webcompat/api/endpoints.py               100     22    78%   110-117, 128-130, 132-133, 163-169, 182-183, 201-203

@miketaylr ah just realized this

https://github.com/webcompat/webcompat.com/blob/ad693004dcc017fc56b7a2e85f287948db0075a2/tests/unit/test_api_urls.py#L54

And now trying to understand we decided to do that.

[karlcow]

Maybe this needs to be revisited. https://github.com/webcompat/webcompat.com/issues/712#issuecomment-147748826

[karlcow]

That was previous to the work done by bea in https://github.com/webcompat/webcompat.com/pull/1588

And we could revert the decision of webcompat.app.config['TESTING'] = False and adjust the tests. That seems not good to make a special case of api.
