[jeanhl]

I added docs to the unittests.

Edit:
r? @karlcow

Sorry for the mess and thanks for being so patient with me

[karlcow]

@jeanhl I guess you are referring to #1369

first of all, Thanks! There are a couple of things to fit in the convention of this project.

See the format of the contribution done on #1392 and interactions with @miketaylr
There are a couple of things missing in your contribution: format and style. It is explained in
https://github.com/webcompat/webcompat.com/blob/master/CONTRIBUTING.md#submission-guidelines

• The commit(s) should contain the issue number and be explicit about what they do.
• The Pull Request should have a title starting with "Fixes #NNNN - "
• The Pull Request should ask for a review (see top right for example. Reviewers). You can ask me or @miketaylr

@jeanhl thanks for the pull request.

so to be really in harmony with the CONTRIBUTING guidelines, you need to change the commit message. Usually we do:

git commit -m '#1369 - Adds docstrings to form tests' tests/test_form.py

• #1369 so the commit is automatically referenced in the issue.
• Adds aka imperative voice instead of Added (this is more a question of style). Think about it as "This commit does something" instead "I did something".

I will review your commit.

If you are not comfortable with rebasing. I'll do it.

[jeanhl]

Thank you! These are very helpful feedback. I'll revise the docstrings and do a new commit tomorrow morning. :)

[jeanhl]

I made the changes and committed them

[karlcow]

Thanks a lot @jeanhl I will rebase it to have a cleaner commit.

Thanks Karl! 😃
