In this article, see six of the best API testing tools available on the market, including Katalon Studio, Postman, SoapUI, Tricentis Tosca, JMeter, and Rest-Assure. API test is a significant part of a successful Continuous Integration/ DevOps practice.
API test is a significant part of a successful Continuous Integration/ DevOps practice. As per Google Trends, the interest in Web/ API services tests has been progressively growing over the few decades. According to SmartBear research over 3,372 software professionals in API test over 2019, 91 percent of participants either presently have, or thinking to have a formal API test procedure in place in the coming future. Around 45 percent of API testers reported that their company already automated 50% or more of test projects. Moreover, by more than 75 percent of companies across industries, API quality is considered a top priority.
With APIs more and more becoming crucial elements for software development, it has become critically essential for programmers and developers to carry out API testing. API test is a procedure that concentrates on identifying whether an API that has been developed meets up the expected threshold concerning security, reliability, performance, and functionality. As these tests are crucially vital, you need to make use of the top API testing tools out there.
• API consumer or Target Audience
• Test for normal situations
• Testing aspects
• The surroundings in which the API is going to be used
• Tests for negative tests or abnormal conditions
As more and more companies make the shift left toward continuous deployment (CD), continuous integration (CI), and DevOps, test feedback requires being faster than ever. Concentrating completely on User Interface automation which is particularly time-consuming could kill your automation testing efforts. As you scramble to ensure that your apps are prepared to ship, API tests must be a component of your complete automation strategy.
APIs are the base of new and advanced software development, as more and more teams move away from monolithic apps and start adopting a microservices technique for software development. Through microservices that are making up the backbone of most modern development efforts, API tests turn out to be even more crucial than before.
Because of the API test’s nature, it cannot be manually tested, and we have to go for some best of the API test tools to tests APIs. Here, I have compiled a list of the top API testing tools in the market.

It is a collaboration platform for Application Programming Interface development. It is one of the most popular API clients. *Postman *enables us to plan, build, share, allocate, test, & document APIs. Originally postman was only a Google Chrome plugin. At present, it extends its solution with the native versions of Mac and Window. If in case you do not wish to code then you can select Postman for your API test.
Postman is one of the best choices for API tests for beginners who do not want to dive under coding in an IDE (integrated development environment) using a similar language as the software developers. Starting from advanced version 7.3 in 2020, this amazing tool assists users in better manage the collections and API elements (monitors, mock server, tests, and documentation) created from API schemas by using the most modern preferences. The current version 7.31.1 for Linux, Windows, and Mac App has been released in Aug 2020 with slight bug fixes.

• Supports Continuous Integration/Continuous Delivery service with Newman
• Simple-to-use REST client
• Supports run, test, document, and monitor features
• The rich interface that makes it simple to use
• Can be used for both exploratory and automated testing
• Supports RAML & Swagger formats
• No requirement to learn a new language
• Allow users to simply share the information with the team as they can wrap up all the requests and possible responses, and then send it to their teammates
• Even though the company version is easy to install and use, it comes with restricted requests
• Pricing for business is too high

API endpoint when you send the get request to that URL it returns the JSON response. In this article, I am going to use postman assertions for all the examples since it is the most popular tool. But this article is not intended only for the postman tool.
APIs can be as simple as 1 endpoint for use by 100s of users or as complex as the AWS APIs with 1000s of endpoints and 100s of thousands of users. Building them can mean spending a couple of hours using a low-code platform or months of work using a multitude of tools. Hosting them can be as simple as using one platform that does everything we need or as complex as setting up and managing ingress control, security, caching, failover, metrics, scaling.
