How does it help me choose which test double to use?

It includes a built-in decision matrix that analyzes if you need to verify calls, record interactions, or provide real simplified logic to determine the best type.

Does this skill support PHPUnit's native mock builder?

Yes, it generates standard PHPUnit createMock and createStub patterns, including support for argument matching and consecutive call sequences.

Is the generated code compatible with the latest PHP versions?

The skill is specifically optimized for PHP 8.4 and adheres to modern PHPUnit 10+ testing standards and strict typing.

Can it generate manual classes for Fakes and Spies?

Absolutely. It can generate standalone classes for complex testing needs like In-Memory repositories or Frozen Clocks for time-dependent code.
