Rationale
The advantages of this framework:
- faster
- runs every test case in a clean WordPress install
- uses the default PHPUnit runner, instead of custom one
- doesn't encourage or support the usage of shared/prebuilt fixtures
It uses SQL transactions to clean up automatically after each test.
Current Status
This framework has been ported to the official testing suite.
