What are API Testing Tools for Swagger?

API testing software is used to test and validate the functionality, performance, security, and reliability of Application Programming Interfaces (APIs). These tools help ensure that APIs perform as expected under various conditions and meet the required business and technical requirements. Features typically include automated testing, request/response validation, load testing, security testing (e.g., for vulnerabilities and authentication), and performance testing. API testing software often supports integration with continuous integration/continuous deployment (CI/CD) pipelines to facilitate automated testing as part of the software development lifecycle. Compare and read user reviews of the best API Testing tools for Swagger currently available using the table below. This list is updated regularly.

vREST

vREST

Validate response of your REST APIs. Write Test Cases, Run them, Validate it's Response, Find out failure reasons using Diff Report, and much more. Powerfully integrate tools like JIRA, Jenkins, Team City, Bugzilla, Slack etc. Easily pluggable with any build or continuous integration system and lets your team remains in sync on test failures. Using API Mocks, your front-end team won't need any back-end API for their development. It means that your front-end team can work in parallel with the back-end teams. Apart from it's Easy-To-Use interface and Great Customer Support Team, there are some features that make vREST stand apart in its competition. Feeling lazy to write test cases? Don't Worry, in vREST you can simply record test cases by manually using your application once. vrunner lets you execute your test cases just by running a command on your terminal. So every time you deploy your application, you just need to Run a Command to validate your APIs.

Pynt

Pynt

Pynt is an innovative API Security Testing platform exposing verified API threats through simulated attacks. We help hundreds of companies such as Telefonica, Sage, Halodoc, and more, to continuously monitor, classify and attack poorly secured APIs, before hackers do. Pynt's leverages an integrated shift-left approach, and unique hack technology using home-grown attack scenarios, to detect real threats, discover APIs, suggest fixes to verified vulnerabilities, thereby eliminating the API attack surface risk. Thousands of companies rely on Pynt to secure the no. 1 attack surface - APIs, as part of their AppSec strategy.

SOAtest

Parasoft

Anchored in artificial intelligence (AI) and machine learning (ML), Parasoft SOAtest simplifies the complexity of functional testing across APIs, UIs, databases, and more. Change management systems continuously monitor quality, making the API and web service testing tool a perfect fit for Agile DevOps environments. Parasoft SOAtest delivers fully integrated API and web service testing tools that automate end-to-end functional API testing. Streamline automated testing with advanced functional test-creation capabilities for applications with multiple interfaces (REST & SOAP APIs, microservices, databases, and more). The tools reduce the risk of security breaches and performance outages by transforming functional testing artifacts into security and load equivalents. Such reuse, along with continuous monitoring of API for change, allows faster and more efficient testing.

RestSequence

Opcito

RestSequence is a no-code platform that allows users to create end-to-end product test workflows by using underlying product-under-test APIs. It enables users to create, manage, and execute test cases and scenarios efficiently. By harnessing the power of their application's Swagger API collection, RestSequence empowers users to quickly design and test scenarios, guaranteeing superb application performance and reliability. With RestSequence, you can onboard generated test scenarios, integrate them into your CI/CD pipeline, and run them on nightly, weekly, or release builds. The best part is that the output file generated once using RestSequence can be used for future testing scenarios without making any changes. RestSequence reads and parses API details (method, URL, payload, request body, etc.) from a Swagger specification file. It tests each API endpoint for correct responses, status codes, required fields, and invalid data, tracking the created resources during test execution.
