A comprehensive guide to testing API edge cases, input validation boundaries, and security vulnerabilities that attackers exploit but developers rarely test. Master advanced API testing techniques to uncover hidden vulnerabilities in input validation, authentication, and error handling that standard testing misses.
By treating the OpenAPI specification as the single source of truth, teams can design APIs up front, generate always-accurate documentation, enforce contract-based tests, and even auto-produce client SDKs and server stubs across languages. This eliminates drift between code, tests, and docs, reduces duplication, and creates a shared foundation that streamlines collaboration throughout the API lifecycle.
