Find a visual way of representing your tests - e.g. a mind map, diagram, model, etc.
I'm trying to get proficient with MindMup.
Looking down the list of these '30 days', you're probably going to see a lot of mindmups on this blog in the near future.
Anyway, I'm having to test a combination of a bunch of options on a screen.
So, I've mindmupped it out into the important things to verify!
The next task will be to reduce the final points on the tree to a nice set of combinations - rather than testing every possible combination. Fun times!
