Regression testing is a vital software testing process that verifies existing functionalities after making code changes. It helps detect defects, ensures product stability, and maintains overall software quality. Automated and selective regression testing streamline the process, and tools like Selenium, TestNG, and JUnit enhance efficiency and accuracy.
- Detect Defects: Identifying and catching any new defects or bugs introduced by code changes.
- Ensure Stability: Verifying that existing features and functionalities are not negatively impacted.
- Maintain Quality: Ensuring the overall quality and reliability of the software product.
- Manual Regression Testing: Carried out by human testers, involving meticulous checks of each feature.
- Automated Regression Testing: Utilizing test scripts and tools to execute repetitive tests more efficiently.
- Selective Regression Testing: Testing only specific areas of the software that are likely to be affected by changes.
- Continuous Integration: Integrating and testing code changes frequently as they are made.
- On Release Basis: Conducting regression tests before deploying the product to production.
- On Fixed Schedule: Performing regression tests at regular intervals, such as after each sprint or iteration.
- Selenium: An open-source automation testing framework often used for web applications.
- TestNG: A testing framework inspired by JUnit, suitable for test configuration and grouping.
- JUnit: A popular Java testing framework for unit testing.
- E-commerce Website – Product Catalog:
- Scenario: A new feature is added to the e-commerce website, allowing products to be categorized based on user preferences.
- Regression Test: Ensure that existing product categories and search functionality still work correctly after the update.
- Mobile Banking App – Transaction History:
- Scenario: A mobile banking app is updated to include advanced search and filtering options for transaction history.
- Regression Test: Verify that basic transaction history retrieval and display functions remain unaffected.
- Social Media Platform – Profile Pictures:
- Scenario: Users are now allowed to upload animated profile pictures on a social media platform.
- Regression Test: Ensure that the ability to upload, view, and manage regular profile pictures is not broken.
- Healthcare Software – Billing Module:
- Scenario: The billing module of a healthcare software system undergoes enhancements to include additional insurance claim processing.
- Regression Test: Validate that the core functionalities like patient billing and payment processing remain functional.
- E-learning Platform – Course Enrollment:
- Scenario: New features are introduced for course recommendations based on user interests on an e-learning platform.
- Regression Test: Confirm that the core functions like course enrollment and access to course materials continue to work without errors.
- Inventory Management Software – Reporting:
- Flight Booking Website – User Authentication:
- Scenario: The flight booking website introduces a more secure authentication method.
- Regression Test: Validate that the existing flight search and booking functions, which require user authentication, remain functional and secure.
- Document Management System – File Uploads:
- Scenario: Enhancements are made to the file upload feature of a document management system to handle larger file sizes.
- Regression Test: Verify that other core functions, like document retrieval and sharing, still operate as expected.
- Purpose: Regression testing verifies existing software functionalities after code changes to catch defects, ensure stability, and maintain software quality.
- Manual Regression Testing: Human testers meticulously check each feature for correctness.
- Automated Regression Testing: Test scripts and tools automate repetitive tests efficiently.
- Selective Regression Testing: Focus on specific areas likely impacted by changes.
- Continuous Integration: Tests run frequently as code changes are integrated.
- On Release Basis: Testing occurs before deploying the product to production.
- On Fixed Schedule: Tests performed regularly, like after sprints or iterations.
- Selenium: Open-source framework for automating web application testing.
- TestNG: Testing framework for test configuration and grouping.
- JUnit: Java testing framework for unit testing.
