Wire tests verify HTTP protocol communication using MockWebServer and are generated for all endpoints in a service. ```yaml customConfig: enable-wire-tests: true ``` Generated tests include: * Working 404/500 error tests that compile immediately * Success test templates with TODO comments for customization * Proper handling of staged vs regular builders * Constants for all magic strings for better maintainability Note: Complex request bodies and response validation require manual customization.
