With software development becoming exponentially more complex with each passing year, automation is becoming a critical part of the software development process. Automated API testing strategies are able to run detailed tests on software solutions, reducing developer burden while still maintaining product consistency and quality.
Automated API Testing Strategies
Automated API testing bypasses the GUI layer of a product to test the application’s API integration directly. Rather than developers having to manually test the API as new iterations of the software are completed, the API testing strategy can instead run a gauntlet of automated tests to ensure that nothing has become broken in the process of development. APIs are becoming more important as software becomes more complex and integration into a larger and broader ecosystem becomes necessary.
Automated API testing will run a number of scenarios and simulations for the control and the flow of data across the application, and both to and from the application, to ensure that the data is being transferred correctly and processed by the API as it should be. Automated testing can run through many case scenarios and simulations very quickly, whereas a manual tester might need to take hours (or even days) to test every aspect of the application’s integration.
The Growing Need for API Testing
Applications are increasingly becoming reliant upon APIs as software becomes more complex, and applications must interact with more layers and more products for their functionality. The module-based architecture of many software solutions demands API integration, but API integration can be easily interfered with during the process of development and patching.
Automated API testing strategies greatly streamline the development and testing process, by cutting the developers out of the testing equation and automatically testing large numbers of APIs at once. This makes it possible for developers to focus on other areas of the product, such as managing the user experience and the internal functionality of the product.
Creating an Automated API Testing Strategy
An automated API testing process can be driven by either commercial or open source tools, of which there are many. A complete strategy will include when the process is run and who is accountable for running the process and reviewing the results. There will likely be a number of tools involved for different types of testing. Mobile API testing may be different from desktop native API testing and so forth, so a development team may need multiple workflows and processes depending on the type of product they are developing.
A few of the most popular API testing tools include SoapUI, Katalon Studio, Postman, Rest-Assured, and Assertible.
The Limitations of API Testing
API testing is intended solely for testing APIs, so automated API testing is not able to test user experiences, user interfaces, or other issues of look-and-feel. They are solely designed to test APIs: to test the integration and communication between products. However, by automating API testing, developers can spend more time concentrating on the other areas of the product.
As applications continue to become more complex, the need for automated testing strategies grows. Developers can greatly streamline their operations and improve the accuracy and consistency of their operations by adopting automated API testing processes.
