What is API testing?
API testing is a type of software testing that focuses on the application programming interface (API) to determine if it meets expectations for functionality, reliability, performance, and security. API testing can be done manually or automatically, and it is often part of integration testing or regression testing. API tests are important because they can help to find problems with the API before the software that uses the API is released. This can save time and money by preventing release delays and expensive fixes. Automated API tests can also be run frequently as part of a continuous integration or delivery process to ensure that the API continues to work as expected. There are many different ways to test an API, but some common methods include sending requests and checking responses, comparing results against a known baseline, or using specialized tools to interact with the API. Testing an API also involves verifying that authentication and authorization are working as expected. ...
