How does it structure tests?

It enforces the Arrange-Act-Assert (AAA) pattern to ensure tests are readable, independent, and maintainable.

Can I use it for existing codebases?

Absolutely; it is designed to help refactor existing tests and improve code coverage for legacy projects.

What platforms does this skill support?

It provides specific guidance and patterns for Web, Mobile, Backend, and AI platforms.

Does it help with flaky tests?

Yes, it includes specific strategies to avoid anti-patterns like shared mutable state and implementation coupling that cause non-deterministic results.

What test design techniques are included?

It uses Equivalence Partitioning (EP), Boundary Value Analysis (BVA), and heuristics like CORRECT and Right-BICEP.
