As a Marketing Director in an affiliate network, it's crucial to design comprehensive API test cases to ensure seamless functionality across multiple partners and data streams. An effective approach is the "Equivalence Partitioning" and "Boundary Value Analysis," which divides input data into equivalent partitions for uniform processing while also testing values at the boundaries, ensuring thorough coverage in API testing.
When designing API test cases, use functional, non-functional, and exploratory testing for a comprehensive evaluation. Start with functional testing by listing API endpoints and creating test cases to verify response accuracy and error handling. Non-functional testing should assess performance, security, and usability. This combined approach ensures the API meets business requirements and performs reliably under various conditions.
