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

@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?

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

@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.

I see. Thank you.

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

Done!
