Regression testing is boring… only if you are doing it manually.
Indeed, it’s just not efficient when you have to manually repeat the same test steps over and over. Regression testing is best done with a regression testing tool. These tools allow you to create an automated regression test suite that you can run as a batch whenever a new build is available.
Let’s check out the top regression testing tools on the current market. Here's the list:
- Katalon [Great For All Purposes]
- Selenium [Great For Web Testing Automation]
- Cypress [Simple and Intuitive Framework]
- Applitools [Strong in Visual Testing]
- testRigor
- Tricentis Tosca
- Leapwork
- Apache JMeter
- Rainforest QA
- Postman
1. Katalon [Great For All Purposes]
Katalon supports automation testing for all AUTs: web, desktop, mobile, and even API. You can write regression test scripts without coding. Katalon offers three modes of test authoring:
1. No-code mode: Turn on Record-and-Playback and manually execute the regression test case. Katalon captures your actions and converts them into a reusable test script.
2. Low-code mode: Build a full test case from Katalon’s library of keywords. Example: choose the “Click” keyword, specify the target element, and Katalon generates the action automatically.
3. Full-code mode: Switch to scripting mode for maximum customizability. You can freely switch between all modes as needed.
All regression test cases can be grouped into test suites and test collections. These are stored in the Object Repository, where you can tag them, view status/results, and schedule executions across environments.
During execution, you can choose device type, OS, version, and browser—allowing wide coverage of real-world scenarios.
After execution, Katalon generates detailed test summary reports for full visibility into project quality.
Have a quick look at how to do regression testing effortlessly with Katalon:
Other Key Features:
- AI-powered features built-in to generate test scripts from natural language, explain code, or even analyze web traffic to provide regression test recommendations.
- Supports data-driven testing.
- Diverse integration ecosystem supporting all stages of the STLC with native plugins for CI and DevOps workflows.

2. Selenium [Great For Web Testing Automation]
Selenium is favored by developers worldwide for its versatility in web testing. It is compatible with all major browsers — Chrome, Safari, Firefox — and supports all major operating systems including macOS, Windows, and Linux.
It offers three key tools:
- Selenium IDE: A Chrome/Firefox extension with Record-and-Playback for fast test creation.
- Selenium Grid: Executes tests in parallel across browsers and machines.
- Selenium WebDriver: A powerful automation library with deep browser control.
The Catch: Selenium requires strong coding skills. Teams transitioning from manual testing often need ramp-up time.

3. Cypress
Cypress is an end-to-end testing framework designed for modern web apps, offering simple syntax for writing, running, and debugging tests.
Cypress and Selenium differ in key design choices:
- Execution: Selenium uses WebDriver (adds latency). Cypress runs inside the browser (faster).
- Waits: Selenium requires explicit waits. Cypress auto-waits for elements and assertions.
Key Features of Cypress:
- Control server responses, timers, and function behavior with spies and stubs.
- Test edge cases without server involvement.
- Fast, reliable tests with automatic screenshots on failure.
- Runs on Firefox, Chrome-family, Edge, and Electron.

4. Applitools [Great For Visual Regression Testing]
Applitools is an AI-driven visual regression tool that ensures UI changes do not break the user experience. Instead of pixel-based comparison, it uses smart visual AI to avoid false positives caused by animations or dynamic content.
Key Features:
- AI-powered visual analysis that detects real regressions like a human eye would.
- Configurable ignore regions for dynamic areas like ads or personalized content.
- Integrates with Cypress, Selenium, and CI/CD tools (Jenkins, GitLab, CircleCI).
- Jira and bug tracker integration for better reporting.

5. testRigor
testRigor simplifies test automation with generative AI, allowing teams to write and maintain tests in plain English. You can even paste manual test steps directly.
Here’s an example — in testRigor, creating a test case can be as easy as typing the action you want to automate:
Key Features:
- Create tests in plain English for easy authoring and maintenance.
- Supports web, mobile, desktop, API, and 2FA testing across 3,000+ device/browser combinations.
- Handles file validation, OCR, and Chrome extension testing.
- Integrates with CI/CD, test management, and ticketing systems.
- Supports JavaScript execution and reusable test steps.
