How is API Automation Testing Beneficial?

The application programming interface (API) is used mainly for establishing contact between various software programs. Technological companies use Automated API Testing mechanisms to avoid common mistakes and meet the specifications set by their clients. This app is responsible for ensuring that the software framework meets its desired specifications. But before moving on to its potential advantages, it is better to have a brief idea of what automated testing is and how it works.

API Testing

The term API stands for an application programming interface. The software API is a set of procedures that innovators use to open up other innovators' apps for transmitting and interacting with each other's apps for transmitting and interacting. After building an API, it is highly necessary to modify the interface to provide a secure, reliable, and scalable connection between various platforms.

There are three main aspects to API testing:

  • Functional API Testing

This part is mainly responsible for checking the functionality of the API. It takes a payload in the form of JSON or XML to provide the response code or response body.

  • Loading API Testing

It is responsible for modifying the specific load acquired and the traffic that can be handled by the API.

  • Security API Testing

It is responsible for checking for vulnerabilities like authenticating or encrypting a specific set of data.

Benefits of API testing

  • Increases time efficiency

In the development process, the API cycle can be performed way earlier than anything else because it does not need a GUI to get ready. It also provides quicker results and significantly accelerates the workflow. It also speeds up the feedback process and catches any issues faster.

  • Reduces Cost

The increased execution speed of the automated APIs has led to an efficient consumption of resources. It ultimately results in lower overall testing costs. After the business logic is defined, the API can be executed, resulting in the identification of the issue at an early stage. That means the earlier the issue gets detected, the less it will cost to fix it.

  • Technological development

These API tests are language-independent. Since the data is mainly exchanged using JSON or XML. Therefore, the QA team is free to choose the language of their choice, which is responsible for supporting different technologies.

  • Stabilizes the tests

API interfaces are stable. The GUI is accustomed to change because it accommodates new requests from stakeholders and users, but the API software doesn't. The API software is filled with detailed documents, and changes are reflected there. Due to these inherent tests, they are also much easier to maintain.

  • Test coverage is developed

The scope of API tests is broader in scope and detail compared to the other unit tests. One may encounter several problems while running a unit test, like the intersection where one layer's scope ends and the other begins. But these problems don't exist in terms of API. They are made in such a way that they verify all system components' functions as they are intended.

Conclusion

API Automation Testing is undoubtedly a better way of checking any continuous testing in agile methodologies. It is one of the most crucial tests in software engineering. APIs that need to be adequately checked can often cause problems with other calling apps and API applications.
