Which Rust traits can this skill automatically mock?

The skill can generate MockProvider implementations for Config, HttpRequest, Publisher, Identity, and StateStore traits.

How does the skill handle time-sensitive business logic?

Through the Replayer Pattern, it implements shift_time and normalize_timestamps functions that modify timestamps in test data to match the execution context.

When should I use the Replayer Pattern over the Simple Fixture Pattern?

Use the Replayer Pattern for advanced scenarios involving time-sensitive logic, production data replay, or components that validate timestamps against the current time. For standard request/response validation, the Simple Fixture Pattern is recommended.

Does this skill require specific permissions in Claude Code?

Yes, it is recommended to grant 'all' permissions for the initial shell commands to allow for seamless file generation and cargo compilation without interruption.

Security & Testing

Generates comprehensive test harnesses for Rust WASM components using fixture-based or production-replay testing patterns.

The testgen skill automates the creation of robust testing infrastructures for Rust-based WASM components. It analyzes your component's input/output types and dependencies to implement either a streamlined fixture-based testing pattern or an advanced replayer framework. By generating necessary boilerplate for MockProviders, trait implementations, and time-shifting logic, it allows developers to validate complex business rules and time-sensitive logic with production-grade reliability while significantly reducing manual setup time.
