What is junit test reports?
JUnit test reports are structured documents that provide detailed information about the results of automated tests written using the JUnit testing framework. JUnit is a popular testing framework for Java applications, and it allows developers to write and run unit tests to verify the correctness of their code.
JUnit test reports typically include the following information:
- Test Suite Summary: An overview of the entire test suite, including the total number of test cases and how many passed, failed, and were skipped.
- Test Case Details: Information about each individual test case, including its name, status (pass or fail), execution time, and any error messages or exceptions that occurred during the test.
- Error Messages and Stack Traces: Detailed error messages and stack traces for failed test cases. These help developers diagnose and fix issues in their code.
- Test Execution Time: The time it took to execute each test case. This information can be useful for identifying slow tests that may need optimization.
- Test Coverage (optional): Some test reports may also include code coverage information, indicating which parts of the codebase were exercised by the tests.
JUnit test reports are generated in a structured format, often in XML or HTML, making it easy to parse and display the results. These reports are invaluable in the software development process for the following reasons:
- Test Result Visibility: JUnit test reports provide a structured and detailed view of the test results for a project. They help developers and team members quickly understand which tests have passed and which have failed.
- Continuous Integration: In a continuous integration (CI) pipeline, automated tests are run whenever code changes are pushed to a repository. JUnit test reports in GitLab CI help automate the testing process and provide feedback to developers about the health of their code.
- Regression Testing: JUnit test reports can identify regressions, i.e., when previously working code becomes broken due to recent changes. By comparing test reports over time, teams can catch issues early and fix them before they become larger problems.
- Code Quality Assurance: JUnit test reports are essential for ensuring code quality. When combined with code coverage reports, they help teams assess how much of their code is tested and identify areas that need more test coverage.
- Historical Data: Test reports in GitLab CI are stored and accessible over time. This historical data can be used to track the progress of test coverage and the overall quality of the software.
- Decision Making: Test reports assist in making informed decisions about whether to deploy new code changes or releases. If the test reports indicate failures or issues, it may not be advisable to proceed with deployment until the issues are resolved.
- Documentation: Test reports serve as a form of documentation for your codebase. They provide insights into the behavior and expectations of the code, making it easier for team members to understand and maintain the software.
- Collaboration: JUnit test reports in GitLab CI are easily accessible to all team members, fostering collaboration and enabling everyone to contribute to quality assurance.
- Feedback Loop: The test reports can be integrated with notifications and alerts, allowing team members to be immediately informed when tests fail, helping to speed up the debugging and resolution process.
In summary, JUnit test reports in GitLab CI are a critical part of the software development process, enabling teams to maintain code quality, catch issues early, and make informed decisions about code changes and deployments. They are a valuable tool for ensuring the reliability and stability of software projects.
Junit Test Reports for Maven Project using GitLab CI
Step #1:Build Java Project using Maven in GitLab CI/CD
Follow the below link for Build Java Project using Maven in GitLab CI/CD.
Step #2:Create .gitlab-ci.yml file for junit test report for maven project in your repository
Step #3:To see junit test report for maven project using gitlab CI
Go to build section > pipeline
Click on pipeline after the go to test tab
Click on test-maven-project and you can see test report under the view details
And after that you can see view details of particular suits like below
If your test failed then you can see your report how it looks like
In below test report in your suites 1 failed and 2 passed test
If you go inside test-maven-project you can see failed test in view details.
In view details you can see system output details in that what you have to make changes in your test to pass test.
It means that The Test Summary panel is a useful tool for developers and reviewers to quickly assess the impact of code changes on the test suite’s status. It helps in identifying regressions (tests that were passing but are now failing), new issues (tests with errors), and improvements (tests that were failing but are now passing) within the context of the merge request. This information is essential for ensuring code quality and reliability before merging changes into the main branch.
