The platform enables you to perform unit tests, integration tests, functional tests, mock tests, end-to-end tests, regression tests, and more. With Postman, you can take tests that you would typically have to perform manually and run them through an automated system. Postman is an automation and development tool that you can use to build an API for your app and automate the tests you need to make sure the API is working correctly. The automation tool receives back the API’s output and records the information it receives, which can be checked against an expected result. API tests use calls sent from an automation tool to your app’s API. It’s a way of checking the performance, reliability, and functionality of your app’s API.Īs mentioned before, API testing ignores the graphical interface that a user would touch and focuses entirely on the application layer (OSI model) of your software. This allows for the fast transmission of information while still providing everything your app, program, or service needs to operate.ĪPI testing is a means of verifying that two software systems, which could also be your API and own UI are able to talk to each other without issue.
Now, you would separately build an API and then also build a UI on top of the API.ĪPIs work behind the scenes and transport only raw data, since there’s no human interface that would require the data to be presented in a visually appealing way. These days, web applications are built in an API + UI fashion, so you don’t need to build a monolithic “web app” as before. This is a way for your app to pull information from a database or website, or give information to an app requestion information. What is API testing?Īn API, or application programming interface, is what your app, program, or service uses to communicate with other apps, programs, or services.

Manual API testing can be time-consuming, but fortunately there are tools to automate and ultimately speed up the testing process.
Testing before and after release can eliminate these issues that could plague your users. A buggy API would mean your app is unable to communicate correctly with other systems. Along with user interface testing and feature testing, confirming your app’s API works as it should is integral to the successful launch of your product.
