APIs serve as a link between devices, products, assets, and other items and the applications that utilize the data they provide. APIs are important in terms of data since they act as conduits between the web/mobile app and the device and between the system and its components. They must be tested to ensure that the data is appropriately represented. Many bugs in the application can be resolved by testing the API, but adhering to recommended practices will always reduce flaws.
#API testing is essential for automating testing since APIs are increasingly the primary #interface to #application logic. Click To TweetGUI tests are challenging to maintain with Agile software development and DevOps’ short release cycles and frequent changes.
API automation testing and any testing activity that adheres to basic standards and best practices will always be able to survive or surpass any adverse testing conditions.
With the GUI, integration is simple
API testing allows for highly integrable tests. This is especially useful if you intend to follow up your API testing with functional GUI testing. Easy integration would allow new users to be created within the program before a GUI test.
Reduces testing time
Automated API tests deliver substantially faster test results and significantly speed up development workflows. To begin, API tests do not require completing a GUI. They can be conducted early in the agile development cycle, allowing you to shorten the feedback loop and discover issues sooner. API tests take a lot less time.
Test for Core Functionality
A common problem for many software developers is testing their app’s functionality long before building a user interface. To give their code a test run, they either connect it to a fake version of the UI or create a dedicated testing utility. It can be challenging to expose an application’s core functionality with business applications without a front end.
Although simplifying the GUI allows dedicated testing tools to be built faster, these aren’t actually processing live data from the database. Building both teams simultaneously in parallel gives you early feedback about how your application performs with accurate data, significantly improving development cycles and overall project success.
Language-Independent – JSON or XML
Another advantage of automated API tests may be run in any language. Data is exchanged via XML and JSON forms for transmission over the Internet, so QA engineers can use any programming language that supports these technologies (JavaScript, Java, Ruby, Python, PHP, etc.) regardless of the application languages.
Access Without UI
Access to the application without a user interface or users to engage with the system is a fundamental benefit of API testing. To portray it another way, QA testers can run API tests without using the software application all by themselves. This is a tremendous benefit since it gives QA engineers early access to flaws and problems, allowing the developers to fix them before they affect the user interface.
Conclusion
API automation testing has become a crucial part for any application development. It allows automation testing teams to test all possible scenarios and get deeper visibility into the application. In addition, API automation testing allows testers to test the application throughout the software development lifecycle, from the early prototyping to the release. It also helps to assess the risk factors and identify the weak points in the application. Today, companies face the increasing challenge of delivering high-quality applications to their customers. With API Automation testing, the teams can provide a high-quality product for a competitive market.
