Can this skill help with legacy Ruby code?

Yes, it provides patterns for partial mocking and stubbing to help isolate legacy components and collaborators during refactoring.

How does this skill improve test performance?

It offers configuration strategies and optimization techniques, such as using instance doubles, to reduce test suite overhead and improve execution speed.

Is this skill suitable for Behavior-Driven Development (BDD)?

Absolutely. It emphasizes RSpec's BDD-style syntax and verified doubles to ensure your test expectations match the actual behavior of your objects.

What RSpec mocking strategies does this skill support?

It covers a full range of strategies including doubles, stubs, mocks, spies, and partial mocking for flexible and robust Ruby testing.
