Very interesting. Previously I've seen two similar ideas:
1. Reduce the test data by property-based tests' auto shrinking a là QuickCheck [1]
2. Reduce the change set to a codebase, a là delta debugging [2]
The reducer is able to do both at the same time in a pretty generic way, with some restrictions on the expressivity. Seems to be a good fit for end-to-end tests.
