Get code coverage back over 80%

[ayld]

So fixing #19 dropped test coverage by 20%, because it turns out 20% of all tests were integration tests, which is not ideal, to say the least :D

The Minimizer should be unit tested! If it can not be unit tested, it should be cut down and then unit tested mercilessly!

Overall the goal of this issue is to get coverage back to ~80%

I actually disabled the tests. Will fix them, worry nawt!

Erm, when?
They are currently enabled, the CI runs them.

I can also see that they've been running in the last 10 or so builds.

I can also see that the coverage fell after my commit, so this issue is mine !!
For I SHALT REPENT FOR WHAT I HAVE DONE!! bows head in woeful shame

[tishun]

haha

Win!

Coverage is up by 5%.
Will try to get it over 80%.
