1. Detailed introduction to regression testing:
Regression Testing (RT) is a software testing method used to verify whether the modified software system still maintains the correctness of its original functions after making new changes. It is designed to ensure that modifications to a software system do not introduce new bugs or cause degradation of existing functionality. Regression testing usually occurs after new versions, patches or feature enhancements of the web and mobile versions of the online shopping system.
The core idea of regression testing is to detect whether new defects are introduced or cause failures of existing functions by re-executing a set of existing test cases. It helps the development team identify and fix problems caused by code modifications and verify whether the modified online shopping system still meets the expected functionality and performance requirements.
2. Usage scenarios:
- When the online shopping system undergoes feature enhancements, new features are added, or existing features are modified, regression testing is required to ensure that the modified system still works properly.
- When a defect or vulnerability in an online shopping system is fixed, regression testing is required to ensure that the fix does not cause problems with other functions.
- When the configuration, environment or platform of the online shopping system changes, regression testing is required to ensure the stability and compatibility of the software in the new environment.
- When the dependencies or third-party components of the online shopping system change, regression testing is required to ensure that there are no problems with the integration of the system with the new dependencies or components.
3. Common technologies and tools:
- Automated testing tools : such as Selenium WebDriver , Appium , JUnit , TestNG and RobotFramework, etc., can help automatically execute regression test cases and improve efficiency and consistency.
- Version control system : such as Git , SVN, etc., used to manage the versions of test code and test data to facilitate tracking and rollback of modifications.
- Defect management tools : such as JIRA , Bugzilla , etc., used to record and track defects and issues discovered during regression testing.
- Integrated development environment (IDE) : such as Eclipse , IntelliJ IDEA, etc., providing functions for development, debugging and running tests.
4. Specific implementation methods:
- **Determine the scope of regression testing:** Based on the changed online shopping system parts, functions and impact scope, determine the functional modules and test cases that need to be tested for regression.
- **Create a regression test suite:** Based on the regression test scope, select and combine existing test cases to form a regression test suite, including basic functions, core functions, and common paths.
- **Execute regression testing:** Execute the test cases in the regression test suite, verify that the online shopping system still works properly, record and report the defects found.
- **Automated regression testing:** For regression tests that need to be executed frequently, you can consider using automated testing tools to write and execute regression test scripts to improve efficiency and accuracy.
- **Defect Management and Tracking:** Record defects found during regression testing into defect management tools and track the fixing and verification process of the issues.
- **Regular execution of regression testing:** Based on the online shopping system version release cycle or frequency of changes, establish a plan for regular execution of regression testing to ensure the stability and quality of the system.
Regression testing is an important testing activity that can help the team discover and solve problems in a timely manner during the development process of the online shopping system and ensure the stability and reliability of the system. It requires multiple executions at different stages of software development, combined with automated testing tools and appropriate testing strategies to maximize coverage of the system's functions and scenarios.
5. Regression test cases
| Test case number | Test target | Prerequisites | step | expected outcome | Pass/Fail | Remark |
|---|---|---|---|---|---|---|
| TC001 | Function enhancement | The system has been upgraded to a new version | 1. Open the online shopping system 2. Perform the operation of adding new functions |
New features are displayed and operational normally | pass | |
| TC002 | Bug fixes | System has fixed certain defects | 1. Enter the affected function module 2. Perform the repair operation |
The defect no longer recurs and the function operates normally. | pass | |
| TC003 | environmental change | System migration to new server | 1. Configure the new server environment 2. Start the online shopping system |
The system can start and run normally | pass | |
| TC004 | Component integration | Update payment component version | 1. Replace the old payment component with the new version 2. Perform payment operations |
The payment function works normally and is integrated with the new version of components without errors. | pass |
The above is an example of test case design for regression testing, which is used to describe each test case number, test goal, preconditions, execution steps, expected results, test results and other information. Specific test cases can be designed according to the actual system and test requirements to ensure that key functions and scenarios are covered, and the content of each field can be filled in according to the specific situation.
