Why Public Research Notes?
Mutation testing is how we verify the test suite itself. By intentionally injecting faults into the plugin, we identify where the testing framework needs to improve—and then we improve it.
This page documents that cycle: what we found, what we fixed, and how the framework got stronger. Engineering rigor, documented in the open.
If you encounter unexpected behavior our tests haven't covered, we want to hear about it.
