Best Tools For API Automation Testing

API testing aims to check a program’s interfaces’ functionality, usability, performance, and security. In API Testing, you use software to send calls to the API, get output, and write down the system’s response instead of using regular user inputs and outcomes.

Due to Interface, API testing differs from other forms of software testing. Yet, it expects you to set up an environment that invokes the API automation with a required set of parameters and then finally analyzes the test result.

This blog includes an overview of the top API testing resources that testing teams may pick to meet their needs, covering both open-source and commercial solutions.

1. Katalon Studio

Over 600 positive reviews have been received by Katalon Studio, asserting its place at the forefront of the industry for API automation

Katalon Studio is a free API, Network, Desktop apps, and mobile apps test automation platform. It is emerging as a leading platform for testing API/Web services and positioning itself for developers and testers as a robust end-to-end automation solution.

With different types of commands and parameterization functionalities, Katalon Studio supports both SOAP and REST requests. 

Also, among the top API tools, the ability to combine UI and API/Web services for different environments (Windows, Mac OS, and Linux) has been considered a unique benefit of Katalon Studio.

2. ACCELQ

For functional and API test automation, ACCELQ is a codeless test automation tool. It provides free access for its users. Qualified plan for ACCELQ API starts from $70.00 per user month.

It offers regression suite preparation with monitoring criteria associated with business processes with complete visibility of execution tracking and defect tracking integrations. ACCELQ brings into a codeless environment, the discipline, versatility and strength of traditional code-based setup. 

Like a well-designed and programmed code-based approach, ACCELQ’s natural language abstraction produces a correctly readable and easily executable Java code.

3. SoapUI

SoapUI, a headless functional testing tool, is dedicated to API testing, which allows users to quickly monitor REST, SOAP APIs, and Web Services. 

If your team has complex API test scenarios and is weighted towards QA/test engineers, SoapUI is the tool to try first, especially if it mostly does API testing. 

This functioning research tool is entirely dedicated to API testing, so why would anyone manufacture a scratch solution? So, if you need to build a custom workflow or feature for some purpose, you can use Groovy to code your SoapUI solution.

4.  Postman

Postman is a Google Chrome plugin which can be used to test API services seamlessly. For checking web services, it is a powerful HTTP client. If you are looking for a good option for API testing, you can go for Postman for manual or exploratory testing.

People who do not want to deal with coding in an integrated development setting can use the same language as the developers, Postman’s choice for API testing.

5. JMeter

While JMeter was designed for load testing, many folks used it for functional API testing. 

It includes all the features you need to test an API in JMeter, plus additional features that can boost your API testing efforts. 

JMeter can work with CSV files automatically, so your teams can quickly generate unique parameter values for your API tests. It also integrates with Jenkins, so that your CI pipeline can include the relevant API tests.

Conclusion

There are thousands of testing resources for API testing accessible for use. Every company has different requirements for choosing the best API Automation testing tool. 

Virtually all the above API test tools work well and are great options. The trick is to carefully read through the details and determine which fits your team’s needs best.
