PHPUnit 6 Compatibility

[johnpbloch]

This is related to #84. We will eventually need to support PHPUnit 6. For now, we're just requiring a version >=4.4 and <6.0. Ideally we can support PHPUnit 6.0 and lower, although I'm not sure how, since a lot of the codebase has been restructured (e.g. PHPUnit_Framework_TestCase has been renamed to PHPUnit\Framework\TestCase).

Hi @johnpbloch have y'all made any progress on this?

[ericmann]

We're working on getting things updated. PHPUnit 6 compat is one of several items on my todo list.

@ericmann that would be awesome 👍

Started to take a look into this and it looks like we'll have to wait for Mockery to extend support first: mockery/mockery#728

As far as I could test, any tests (on this repo) that do not require mockery run fine after changing the extends signatures to the new namespaced format.

Now that mockery/mockery#728 is fixed, I have created a PR (#112) that adds support for phpunit 6.0

If you are already using wp_mocks in a project please test the PR.

Fixed in #112
