Efficient API Testing Tools Walk Through
API (Application Programming Interface) was a computing interface which enables communication and data interchange between two individual software systems. Software that executes an API includes several functions/subroutines that another software can perform. API defines requests which will be made, the way to make requests, data formats which will be used, etc. between two software systems.
API testing tools are as follows:
- Postman
- Apigee
- SoapUI
- Katalon Studio
- JMeter
- Pyresttest
- Karate DSL
- Assertible
- Rest-Assured
- Paw
- RapidAPI
- Tricentis Tosca
- RestSharp
- Airborne

Let’s discuss the testing tools
Postman
To begin with a Chrome browser plugin, Postman now extends its solution with the native version for Mac and Windows.
Postman may be a good selection for API testing for those that don’t want to affect coding in an integrated development environment using an equivalent language because of the developers.
Features:
Helps in automated testing.
Assists in exploratory testing.
It allows Swagger and RAML (RESTful API Modeling Language) formats.
It supports knowledge sharing within the team.
Best For The best tool for API testing. It’s rich in features, available for free of charge, and has specialized reviews from its users.
Apigee
Apigee may be a cross-cloud API management platform. It produces security and governance policies for all APIs. Using the open API specification, the tool allows you to create API proxies. With this tool, you’ll design, secure, analyze, and scale APIs anywhere.
Features:
It provides a customizable developer portal.
It supports Node.js.
it presents for the features of IP whitelisting, Java & Python callouts, shared traffic management.
It provides API analytics, Web service callouts, and a few progressive policies like security, mediation, and protocol.
Best For API development.
SoapUI
SoapUI can be a headless functional testing tool dedicated to API testing, make allowance for users to check REST and SOAP APIs and Web Services quickly. The free package: Using the free package of SOAPUI, users can get the complete ASCII text file and build their preferred features.
*Create test quickly and simply with Drag and drop, Point-and-click
*Reusability of Scripts: Load tests and full security scans are often reused for functional test cases during just different steps.
Pro package:
*Powerful data-driven testing: When Data loaded from files, and databases, and Excel so there that they will simulate how consumers interact with the APIs
*Support native CI/CD integrations, asynchronous testing
Katalon Studio
Katalon Studio may be a free test automation tool for API, Web, Desktop App, and Mobile applications. Moreover, the potential of mixing UI and API/Web services for multiple environments (Windows, Mac OS, and Linux) has been considered a distinct advantage of Katalon Studio among the highest API tools.
Feature highlights:
Support both SOAP and Rest
All-in-one buy API, WebUI, Desktop App, and Mobile testing and, therefore, the combined capabilities among those.
It can Support the data-driven approach.
It Can be used for automated exploratory testing
Support CI/CD integration.
Support AssertJ, one among the foremost potent assertion library, to make a fluent assertion with BDD style
useful for both non-techies and pros via Manual and Groovy Scripting modes.
JMeter
It is open-source software for load and performance testing of applications. It supports cross-platform. Jmeter works at a protocol layer. Developers can be used this tool as a unit-test tool for the testing of JDBC database connections. It’s plugins based architecture. Jmeter can generate test data. It supports Command-line mode, which can be helpful for Java-compatible OS.
Features:
It will be allowed to use various programming languages.
Load and performance testing of the many several applications, servers, and protocols.
It also allows you to replay test results.
It also provides support for variable parameterization and assertions.
It can support per-thread cookies.
Configuration variables and a spread of reports also are supported by Jmeter.
Best For: This tool is best for load and performance testing of web applications.
Pyresttest
It was a python based tool for testing RESTful APIs. It’s also a Micro-benchmarking tool. For tests, it supports JSON config files. The tool is extensible in Python.
Features:
Return exit codes for failed results.
The building of test continuity with generate/extract/validates mechanisms.
Because of minimal dependencies, it’s easy deployment on the server, which is useful for smoke testing.
No code required.
Best For RESTful APIs.
Karate DSL
It was an open-source framework for API testing. The karate framework is predicated on the cucumber library. Here this tool, a tester can test web services by writing tests during a domain-specific language. This tool was specially designed for automated API testing and is released by Intuit. To use this tool, there’s no got to have a programming language. But the essential understanding of HTTP, JSON, XML, XPath, and JsonPath are going to be another advantage.
Features:
Multi-threaded parallel execution is supported.
It allows configuration switching.
Reports generation.
It supports reusing Payload-data for API testing.
Best For: It allows you to write down tests in any language which may affect HTTP, JSON, or XML.
Assertible
Assertible is an API testing tool that condenses on automation and reliability.
Allowing for automating API tests through each step of continuous integration and delivery pipeline.
Allow for running API tests after deployments and combines with common tools like GitHub, Slack, and Zapier.
Recognize validating HTTP responses with turn-key assertions like JSON Schema validation and JSON Path data probity checks
The Sync feature and enables testers to update their tests then their specifications change, so users do not want to manually update their tests after adding new parameters or changing API responses.
Rest-Assured
Rest-Assured is an open-source Java Domain-specific language that creates testing REST service more simple.
Have a bunch of baked-in functionalities, which suggests users don’t need to code things from scratch.
Integrates seamlessly with Serenity automation framework to combine the UI and REST tests beat one framework that generates fantastic reports.
Support BDD Given/When/Then syntax
Paw
Paw is a one more beautiful API testing tool specially designed for Mac. Either you’re an API maker or customer, Paw helps you to create HTTP requests, inspect a server’s response, and even generate client code.
RapidAPI
The list of the best API testing tools starts with RapidAPI. RapidAPI is that the largest API marketplace over 1,000,000 developers use to seek out, test, and hook up with thousands of APIs, all with one account. On RapidAPI, you’ll collaborate on APIs using RapidAPI for teams with external and internal APIs. Developers can be used RapidAPI Testing on their internal APIs too with RapidAPI Teams or using RapidAPI Hub.
Tricentis Tosca
Here Another best API testing tool is Tricentis Tosca. If you’re trying to find the endless testing platform for Agile and DevOps, you’ll consider this one so useful. This tools supported many arrays of protocols like HTTP(s), JMS, AMQP, Rabbit MQ, TIBCO EMS, SOAP, REST, IBM MQ, NET TCP.
RestSharp
RestSharp is one of testing solution that you can use for API testing. It can be allowed you to develop .Net APIs and testing them with an equivalent tool.
Airborne
Airborne is an open-source Ruby-based RSpec-driven API testing framework. This tool doesn’t have a UI. It just provides the document to write down the code. It can work with Rack applications. To use Airborne, you only got to remember a couple of crucial methods within the toolset and a few Ruby and RSpec fundamentals.
