Best Practices for API Regression Testing
In today’s fast-paced development cycles, ensuring the reliability of APIs amidst frequent updates is paramount. API regression testing plays a critical role in maintaining software quality by validating that new changes do not break existing functionalities. As serverless architectures rise in popularity, testing strategies must adapt to address unique challenges. This article outlines actionable best practices for API regression testing and explores how Devzery’s innovative solutions empower QA teams to excel.
Introduction to API Regression Testing
API regression testing is a method of re-testing APIs after updates or bug fixes to ensure that pre-existing features remain unaffected. In a CI/CD pipeline, where development moves rapidly, regression testing ensures that frequent deployments do not compromise software quality.
Devzery, a pioneer in AI-powered QA solutions, has redefined regression testing with codeless, scalable tools tailored to modern development needs. In serverless architectures, characterized by dynamic endpoints and ephemeral environments, regression testing becomes even more crucial. This article offers practical strategies to overcome challenges and future-proof your testing workflows.
