😀Tester's Role in API Testing

💡 What is the tester's role in API testing in depth? 👨‍💻

API testing validates the functionality, reliability, performance, and security of an application programming interface (API).

As an API tester, your role involves:

• 📝 Understanding API specifications and documentation to identify all endpoints, request and response parameters, authentication methods, etc.

• 🛠 Developing test cases to validate API functionality by sending requests and asserting responses. This includes happy-path scenarios as well as negative test cases.

• 🔬 Testing non-functional aspects like load, stress, security, failover, etc. This involves scripting tests, setting up tools, and analyzing the results.

• 💾 Validating API integrations with frontends, databases, third-party services, etc. End-to-end testing is crucial.

• 🕵🏻‍♀️ Performing exploratory testing to find edge cases not covered in standard test cases.

• 🤝 Collaborating with developers and product managers throughout the development lifecycle.

• 📊 Logging defects, analyzing root causes, retesting fixes.

• 📋 Maintaining comprehensive documentation like test plans, test cases, reports, etc.

• 🕹 Automating as much as possible using frameworks like Postman, RestAssured, etc.

The role requires understanding of protocols like HTTP, REST, SOAP, web services, and tools like Postman, ReadyAPI, JMeter, etc. Strong analytical and communication skills are key.
