An API or Application Programming Interface allows data to be exchanged between two independent systems. In this case, the systems can include functions of each other. API testing is about requests, where requests are submitted, and how to offer them.
API testing is software testing, where digital programming testing operates. The main goal of such a technique is to determine the interfaces of such characteristics as:
Functionality.
Reliability.
Performance.
Security.
The main feature is that these tests require an application that allows you to interact through the API.
Thus, API is a set of programming instructions for accessing a web application. That is, it is a set of commands that the program uses to interact and use each other’s functions to collect information. An example of an API is the Google website, which may have an API for many features such as searches, translations, calendars, etc.

Introduction to REST API Testing
REST — Representational State Transfer is an architectural and communication technology to develop web services. It is a logical choice for building APIs that allow users to connect and consume cloud services efficiently.
RESTful API Testing or REST API is an open-source automation technique testers use for JSON and XML-based web applications.
REST API testing automation involves two essential components: code created by the tester himself and functions for test tasks.
The Main Criteria for the Best for Rest API Testing Automation
There are many different criteria for choosing a tool, but experienced testers select four of them:
Usability. An API tool should not take much time to master and understand.
Price and quality. Ideally, the rate should even exceed the cost. Or at least be proportionate to each other. Study the price-quality ratio of the tool by its characteristics.
Integrations. Given that QA and DevOp use many different tools. Therefore, the tool should be able to integrate with other elements of the integration and deployment process.
User interface (UI). The visual is also essential. How easy is it to read and understand? How well thought out navigation is and whether it is comfortable enough to use. If you can highlight priority tasks in the immediate context, then the rest API test tool has a good UI.
As a general rule, rest API testing automation is commonly used to test web applications based on JSON and XML.
However, it is compatible with all methods and methods, including:
GET
PUT
POST
PATCH
DELETE. REST.
This test aims to evaluate and record the REST API response by sending HTTP or HTTPS requests to determine how well the REST API is performing.
TOP 8 Rest API Testing Automation
Identifying the best REST API testing automation based on dozens of such tools was challenging. Nevertheless, given such applications’ growth and diversity, we had to disassemble to highlight the most functional and practical. Meet TOP 8 REST API testing automation tools.
ReadyAPI
This is a reasonably popular rest API test tool, which is also suitable for SOAP and GraphQL services. At the same time, this tool performs several API testing of directions at once:
Functional testing.
Performance testing.
Test visualizations.
Virtualization testing.
Website testing.
ReadyAPI provides end-to-end quality and additional flexibility for automation. The tool allows you to create complex API tests and other automation features.
Main functions and features:
It can easily integrate with any environment.
Creates realistic boot scenarios.
Command-line for automated testing.
Built-in support for Git, Docker, Jenkins, Azure, etc.
Excellent compatibility between DevOps and Agile Teams.
ReadyAPI introduces you to create complex and data-driven APIs.
Parasoft SOAtest
It is even more of a REST API automation testing tool collection that will help in both development and automation testing. Parasoft SOAtest performs its critical functions through artificial intelligence, which allows the user to conduct different types of testing: unit, load, etc.
Also, this tool offers particular drag and drop mechanisms and makes it easy to test the API without coding and scripting.
Main functions and features:
Integration of C / C ++ into development through the IDE.
Simplifies compliance with automated testing standards and requirements.
API virtualization.
Equally suitable for both SOAP and REST API testing.
Katalon Studio
Speaking of reliable and comprehensive REST API automation testing tools, we couldn’t help mentioning Katalon Studio. Testers use this for mobile testing, as they do for testing computers and mobile devices.
One of the main advantages is integration with ALM and API/Web services for Linux, Windows, or even Mac OS.
Main functions and features:
The tool has code templates.
It supports CI/CD integration.
Automatic completion of the testing process, updating and checking the code.
Compatible with one of the most potent libraries – AssertJ.
Conducts automated and exploratory testing.
CI/CD integration.
REST-Assured
One tool was created to simplify REST testing in the JAVA domain. This rest API test tool has built-in functions and provides seamless integration with Serenity.
Main functions and features:
BDD Given/When/Then syntax support.
Loyalty in management for the user.
JMeter
It is a cross-platform rest API testing automation tool for load and performance testing. The application can also be used for unit testing and has a plugin-based architecture. JMeter is compatible with various programming languages.
Main functions and features:
Per-stream cookie support.
Test data generation.
Command-line mode.
Presentation of test results.
SoapUI
Another universal tool is equally suitable for both SOAP and REST. SoapUI is an open-source REST API test tool and provides end-to-end testing. Moreover, SoapUI allows you to use various testing methodologies, in particular.
Main functions and features:
Compatible with a wide range of protocols.
Run tests on a large scale.
Versatility.
Tricentis
Tricentis is one of the best options for those looking to integrate it into the Agile and DevOps cycle. This follows model-driven test automation, simplifying scenario maintenance and enabling fast regression testing.
If you are looking for a rest API testing automation tool with integration into Agile and DevOps cycles. If you’re looking to simplify script maintenance and end-to-end testing, then Tricentis is the way to go. This tool has many advantages, in particular:
Support for a large number of different protocols.
Testing cross-browser and packaged applications.
An API is a set of programming instructions for accessing a web application. REST API, in turn, is a category with four main methods: GET, DELETE, PUT and POST. Such testing is necessary to prevent problems associated with applications and their correct operation.
There are dozens of REST API automation testing tools, and some of them demonstrate exceptional functionality and efficiency:
ReadyAPI
Parasoft SOAtest
Katalon Studio
REST Assured
JMeter
SoapUI
