Test Automation for APIs – All you Need to Know

APIs are becoming more and more critical in today’s app development. They connect and transfer data and business logic between systems as the primary mode of communication for web components. It implies that API testing may enhance programme quality and reduce substantial security concerns before going live. We live in an exciting era of intelligence, in which innovation moves at incredible speed. The connected world’s unsung hero is API (Application Programming Interface). In this post we explore Test Automation for API and what the essentials that you need to know. 

 

What exactly is an API?

APIs help systems communicate with one another. You may use an API to make data accessible to other systems or receive data from them. It is how various devices and programs communicate and share data.

APIs are used by successful organisations such as Facebook, YouTube, and Twitter to connect with third-party apps. APIs are often used in the same manner as any other website.

Explain API Testing

API testing is a sort of software testing done directly on the API to see whether it matches the required functionality, security, dependability, and performance. It generally does it by sending straight requests to the API backend rather than loading or interacting with the user interface.

What are the benefits of automation testing?

Automation testing services range from planning and selection of tools to the development and maintenance of a testing automation environment, automated preparation of test data, creation and maintenance of all forms of the automated test script, and more.

Types of API testing

  • Functional testing – Testing specific functionalities in the codebase application is the focus of attention. The goal is to ensure that API functions are within anticipated parameters and that exceptions are appropriately handled if they are not. Test cases for HTTP response codes, error codes, and answers would be ideal.
  • Load testing – This test is conducted to test how much a particular unit or the whole codebase can support. It’s essential for apps that handle a lot of data or have a lot of users. To ensure top performance, determine if the API can handle the predicted load, whether it’s 500, 5K, 50k, or even 100k requests.
  • Security Testing – Security testing is crucial since it helps to assure security against vulnerabilities in your API. As a result, developers should include tests for authorization, encryption, access control, session management, and other API test cases in their API test cases. Fuzz testing and penetration testing both are parts of the API security verification and auditing process, and both guarantee that your API is safe from external threats.
  • Validation testing – One of the most critical but final tests in API implementation. It checks for essential areas of product development, API behaviour, and general efficiency. This form of testing ensures that API development and implementation meet agreed-upon standards and user demands and expectations.
  • Runtime/error detection — This type of test is about how the API works, as opposed to the above tests, which focus on the results of API implementations in a particular scenario. It includes monitoring for irregularities in code implementation, execution, error detection, and resource leaks.

Conclusion

So, a smooth connection with various other apps must be on the checklist when you develop an application. Test Automation for API can be very beneficial to helping you complete this checklist.
