Which tools are best suitable for API Test Automation?

API testing is a well-defined software testing method that ensures that APIs are working efficiently and as per the required expectations. To leverage API testing, API testing tools are used and it proves to be a productive platform for programmers and developers. This is because APIs plays a crucial part in the software development process. To carry out the API automation process effectively and rewardingly, the right tools and solutions can be implemented. API testing tools help in reducing and alleviating problems pertaining to API functionalities. There are many API test automation tools available in the market and the team can take the right decision before selecting the tool that is best suited for their project. In this article, you will get to know the best suitable API test automation tools.   

What is API (Application Programming Interface) testing? 

API testing is a set of QA actions that involves sending calls to the API and then obtaining output. The system’s response is validated against the defined input parameters, in particular, HTTPS status codes, the accuracy of data and data’s format and error codes. A well-defined automation test strategy can be used to enhance the API testing process. 

API testing is conducted on APIs that have been produced by the in-house development team. The API testing approach depends on the API type. There are remote APIs and operating system APIs for accessing resources that have been located outside the device. 

Following are the different types of API test automation tools: 

1. SoapUI: It is one of the best on-premise API testing tools. Through this tool, developers can test GraphQL, SOAP, REST and Web services. It is a sophisticated tool for running, creating and analyzing complicated tests on web services for testing and development teams. It has unique features such as SOAP API testing and test reports. To generate bespoke codes, Groovy can be used. 

2. Postman: It is available in both desktop and browser versions. API services can be easily tested using this tool. The knowledge can be shared by the user with the rest of the team easily. It is quite easy-to-use. It is simple to put up parameters on method calls. It has API development possibilities and the commands can also be easily stored. 

3. RapidAPI: It is the world’s largest API marketplace wherein a single account is used by a colossal number of developers to test, search and connect to thousands of APIs. Teams can use RapidAPI with internal and external APIs to collaborate with APIs.  

4. API Fortress: It is the most valuable SOAP and REST API testing and monitoring solutions provider. It is one of the best tools used for API testing. A wide range of needs are fulfilled by this tool and it is considered to be one of the most efficient API testing tools. API fortress can easily perform complete API testing including regression testing activities also. Some of the key solutions provided by this tool are reporting, notifications, alerts and SLA Monitoring.  

5. JMeter: Functional APIs can be easily tested using this API testing tool. It has several API testing capabilities and features that make the process even more efficient. The performance of static and dynamic resources can be easily tested using this tool. Test findings can be replayed by developers. Command-line interface can be easily utilized by the user-friendly interface provided by JMeter. This tool also supports per-thread cookies.  

6. REST Assured: It is considered to be one of the most efficient tools used for API testing in Java. This tool uses Java Domain-specific language. Web APIs can be easily tested using this tool. There is no need to code from scratch as it has built-in functions. It supports the Then/When/Given syntax of Behavior-Driven Development (BDD) testing. 

Conclusion: If you are looking forward to implementing API testing for your specific project, then do get connected with a reputed and reliable software testing services company that will provide you with well-defined and pragmatic testing solutions that is in line with your project specific requirements.
