@tigarmo Please check if the Python plugin test was updated correctly.

@cmatsuoka LGTM. I wonder if there's a lot of benefit in this kind of low-level testing of the plugin's build commands, but since it's already there we might as well update it.

It could make sense to test when the local plugin changes what's defined in the parent class, but in this case it's just repeating the test, it seems.
