In this article, we’ll focus on in-house web APIs and their quality assurance. There are web APIs aka web services, database APIs that connect applications with DB management systems, operating systems APIs, and remote APIs for accessing resources located outside the device requesting them. The approach to API testing largely depends on the API type. We don’t test third-party APIs, but we can test the way our software accepts their requests. Usually, API testing is performed on APIs produced by the in-house development team. What is API testing?ĪPI testing is a set of quality assurance actions that include sending calls to the API, getting output, and validating the system’s response against the defined input parameters, in particular, the accuracy of data and data’s format, HTTP status codes, and error codes. This time we connect the dots under the topic of API testing. We’ve also elaborated on the basics of software quality management. We have already written in-depth on what an API is.

In this article, we explain why you should do API testing and how to approach it. Some QAs, however, still ignore this layer of the test pyramid and proceed right to UI testing – at their peril. That means it’s crucial to thoroughly verify APIs before rolling out the product to the client or end-users.
