Provide trait-based mocks for Rust code to enable isolated unit tests.
Run cargo test to execute unit tests that use mockall-generated mocks against trait-based interfaces.

Mock Rust traits for isolated unit tests by generating automocks with mockall, allowing you to simulate external service dependencies and control return values without modifying the original trait-based interfaces.
Yes, you can mock asynchronous Rust traits by combining async_trait and tokio within mockall, enabling isolated unit tests for asynchronous code paths that rely on external services or complex dependencies.
Predicate-based matching in Rust mocking allows precise control over mock behavior by matching argument values to specific return outputs, and you can further validate interactions using call counting and sequences.
Yes, mockall supports partial mocks for Rust integration tests through integration with mockall_double, allowing you to mock only specific trait methods while retaining real implementations for others.
You need trait-based mocks for Rust modules when testing code that relies on external services or complex dependencies, enabling you to isolate synchronous and asynchronous logic for reliable unit testing.
