TST: Do not skip MySQL tests on Travis.

[danielballan]

A first step for #4163

Do you only want to test this on 2.7? if not then please add it to the other requirements files. Might be good to test on Python >= 2.7.

[danielballan]

MySQLdb currently does not support Python 3. See https://github.com/farcepest/MySQLdb1

good to know, thanks.

The build failed because of something in pandas.io.tests.test_data.TestYahoo. Should I just try pushing again? Previous test on the exact same code passed.

The error is small, and moreover it's unrelated to my changes.

AssertionError: 
Arrays are not almost equal to 5 decimals expected 904.91000 but got 904.90000

rebase off of master and try again, i just merged a commit to fix that

[danielballan]

Full speed ahead.

Is this running all the tests now? Merge?

[danielballan]

Merge.

[jreback]

does this also correct skip when mysql not installed?

[danielballan]

Yes.
