Protocol conformance drift across implementations can cause unpredictable behavior. This skill provides contract-based tests to enforce a single source of truth for a protocol's expected behavior.
Define your protocol, implement it in a concrete class, and run the contract tests to confirm conformance.

Contract tests for Swift protocol conformance verify that any implementation adheres to a shared specification. You define protocol behaviors and generate reusable test suites that validate implementations like InMemoryDataStore and SQLiteDataStore to ensure consistent behavior.
Protocol contract tests enforce a single source of truth for expected behavior when designing swappable components. You need them when multiple implementations exist, such as real, mock, or in-memory backends, to prevent unpredictable behavior caused by conformance drift across environments.
To validate InMemoryDataStore and SQLiteDataStore, you define required methods, properties, and invariants for the protocol, then generate a reusable test suite. Running both implementations against these contract tests confirms they exhibit consistent behavior across different storage backends.
Yes, contract tests verify mock implementations match real service backends by validating them against the same protocol specification. This ensures that swapping components across different environments does not cause unpredictable behavior or break expected invariants.
No specific testing dependencies are required to generate protocol contract test suites. The skill operates independently to define protocol behaviors and produces reusable tests that validate any concrete class implementation against the shared specification without external libraries.
