Okay, testable code in the runner-refactor branch. Ended up doing a fairly involved refactoring of how runners work with data; which is good, as the new way to structure things makes a lot more sense in general; but it did mean I had to change the data format, so quite a few places this can break.

Currently, multiple host names are separated by commas in the batch file, while multiple test parameters are separated with semi-colons (because the test parameters themselves can contain commas). It would be good to harmonise this as it's a source of confusion; supporting semi-colons for separ
