Automated API testing is a crucial phase of Continuous Integration and/or Continuous Deployment (CI/CD) pipelines and microservices frameworks. This type of testing validates the functionality of API endpoints, measures their performance, and checks for security, functional correctness, or status checks. With the increasing number of APIs being established and integrated, automated REST API testing has become essential to ensure that APIs are functional and meet business logic requirements. Automated API testing can increase test coverage by automating around 95% of important testing definition, execution, and maintenance operations, improving productivity, providing increased observability, and enabling businesses to realize a return on investment by lowering costs over time.
