Bylabel contain

[pythonissam]

Before submitting your PR, check that you've:

• Bumped the version number
• Documented new APIs with Haddock markup
• Added @since declarations to the Haddocks for new, public APIs

After submitting your PR:

• Update the Changelog.md file with a link to your PR
• Check that CI passes (or if it fails, for reasons unrelated to your change, like CI timeouts)

Can you also update the deprecation warnings for the old byLabel to point to byLabelContains for an exact replacement?

[MaxGabriel]

@pythonissam LGTM. Yesod-test 1.6.1 was released after you started this PR though, can you bump the version you're using in your Cabal file, @since docs, and Changelog?

[pythonissam]

Is this alright? Besides, travis seems to fail. Is this okay?

[MaxGabriel]

@pythonissam Yep that looks good. The Appveyor tests were failing because of a merge conflict with master. It looks like all but one of the Travis tests passed (and the failure was unrelated to your changes). I fixed two merge conflicts in your PR, and I'll let CI run on that before merging.

[pythonissam]

I see. Thank you.

[MaxGabriel]

Merged, thanks for your work here @pythonissam!

@snoyberg Can you add me as a maintainer of yesod-test on hackage? I couldn't release this

[snoyberg]

Done!
