Brief Introduction
Regression Testing is a type of software testing is the type of testing which verify that recent changes or updates to a software application have no new bugs. This is because new code may bring in new logic that conflict with the existing code. Normally QA teams have a series of regression test cases for important features that they will re-execute each time these code changes occur to save time and maximize test efficiency.
Why is Regression Testing Important?
Regression Testing is important for several reasons i.e. overall quality, reliability, and maintainability of software applications. Here are some key reasons why regression testing holds significant importance:
- Detecting Defects Early
- Ensuring Software Stability
- Verifying Fixes of Bugs
- Supporting Agile Development (https://www.atlassian.com/agile)
- Facilitating Continuous Integration and Deployment (CI/CD)
- Reduces Risks and Costs & Supports Long-Term Maintenance
- Compliance, Standards & Enhancing Confidence in Code Changes
Regression Testing Tools and Frameworks
Selenium: Selenium is used to run regression tests. Selenium Browser Automation helps run tests on different browsers and find bugs.
Cypress: You can perform E2E Testing and Components Testing on Cypress. This helps you run Regression Tests on browsers using Cypress effortlessly.
Appium: It is used to run regression tests on iOS and Android apps. You can check the functionality of the mobile apps using Appium.
Playwright:Playwright is used for running regression tests for web applications on different browsers.
Puppeteer: You can use Playwright to run regression tests for web applications on different browsers.
BrowserStack App Automate: You can integrate different web testing frameworks, like Appium, Espresso, and XCUITest, with BrowserStack App Automate. It helps you run tests on real Android and iOS devices for better accuracy.
Conclusion: Regression Testing is a fundamental practice in software development that safeguards against regressions in the quality and reliability of software applications throughout their lifecycle. By catching defects early, ensuring stability, and supporting agile practices, regression testing plays a vital role in delivering high-quality software products to end-users.
