Continuous Integration/Continuous Deployment (CI/CD) is crucial in modern software development as it streamlines code integration, automates testing and quality control, accelerates software delivery, and reduces human errors. A CI/CD pipeline consists of stages like source stage, build stage, test stage, and deploy stage, each automated to ensure consistency and speed up the process. The role of testing in CI/CD pipelines is vital as it catches bugs early, ensures consistent code quality, and enables complex API-driven development. API Mocking plays a significant role by simulating external dependencies, accelerating testing, and enhancing test reliability. Continuous Testing with mocks is essential for faster and more reliable code integration in CI/CD pipelines. Integrating an API gateway like Edge Stack into the CI/CD process provides numerous benefits such as automated API management, centralized control of API changes, improved security, scalability, performance, and standardized API governance.
