Negative Testing for More Resilient APIs
Blog post from Postman
In a detailed exploration of API testing, the importance of both positive and negative test scenarios is highlighted to ensure the resilience of applications. The text discusses the concept of "happy paths," where user interactions proceed as intended, versus "unhappy paths," which involve unintended behaviors and inputs that can break a system. It emphasizes that while developers typically focus on happy path scenarios, negative testing—where expected errors confirm robust error handling—is crucial for identifying and addressing vulnerabilities before they cause system failures. The "How to Break an API" livestream serves as a practical example of testing both positive and negative scenarios using the Unbreakable API Lite, demonstrating how engineers and testers can use Postman to simulate and automate these tests. This approach encourages the proactive identification of edge cases that could compromise API functionality, ultimately promoting a culture of resilience in software development.
