* Increased the timeout to a flat 25 second for every build because we
still see the odd, non-reproducible timeout on a variety of machines.
* Removed an extraneous `npm run test-install` which meant we did that
check twice on each CI run.
* chore: Add Windows to Travis
This commit runs the unit tests on Windows.
There are two tests failing on Windows that we skip.
I spoke to Mathias B and we agreed to
defer debugging this for now in favour of getting tests running on
Windows. But we didn't want to ignore it forever, hence giving the test
a date at which it will start to fail.
This commit updates all the non-Puppeteer unit tests to run using Mocha and then deletes the custom test runner framework from this repository. The documentation has also been updated.
