---type:indexdescription:"Testyourcodeanddisplayreportsinmergerequests"---# Tests and reports in merge requestsGitLab has the ability to test the changes included in a feature branch and display reportsor link to useful information directly from merge requests:| Feature | Description ||--------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|| [Accessibility Testing](accessibility_testing.md) | Automatically report A11y violations for changed pages in merge requests. || [Browser Performance Testing](browser_performance_testing.md)**(PREMIUM)** | Quickly determine the performance impact of pending code changes. || [Code Quality](code_quality.md)**(STARTER)** | Analyze your source code quality using the [Code Climate](https://codeclimate.com/) analyzer and show the Code Climate report right in the merge request widget area. || [Display arbitrary job artifacts](../../../ci/yaml/README.md#artifactsexpose_as) | Configure CI pipelines with the `artifacts:expose_as` parameter to directly link to selected [artifacts](../../../ci/pipelines/job_artifacts.md) in merge requests. || [GitLab CI/CD](../../../ci/README.md) | Build, test, and deploy your code in a per-branch basis with built-in CI/CD. || [JUnit test reports](../../../ci/junit_test_reports.md) | Configure your CI jobs to use JUnit test reports, and let GitLab display a report on the merge request so that it’s easier and faster to identify the failure without having to check the entire job log. || [License Compliance](../../compliance/license_compliance/index.md)**(ULTIMATE)** | Manage the licenses of your dependencies. || [Metrics Reports](../../../ci/metrics_reports.md)**(PREMIUM)** | Display the Metrics Report on the merge request so that it's fast and easy to identify changes to important metrics. || [Multi-Project pipelines](../../../ci/multi_project_pipelines.md)**(PREMIUM)** | When you set up GitLab CI/CD across multiple projects, you can visualize the entire pipeline, including all cross-project interdependencies. || [Pipelines for merge requests](../../../ci/merge_request_pipelines/index.md) | Customize a specific pipeline structure for merge requests in order to speed the cycle up by running only important jobs. || [Pipeline Graphs](../../../ci/pipelines/index.md#visualize-pipelines) | View the status of pipelines within the merge request, including the deployment process. || [Test Coverage visualization](test_coverage_visualization.md) | See test coverage results for merge requests, within the file diff. |## Security Reports **(ULTIMATE)**In addition to the reports listed above, GitLab can do many types of [Security reports](../../application_security/index.md),generated by scanning and reporting any vulnerabilities found in your project:| Feature | Description ||-----------------------------------------------------------------------------------------|------------------------------------------------------------------|| [Container Scanning](../../application_security/container_scanning/index.md) | Analyze your Docker images for known vulnerabilities. || [Dynamic Application Security Testing (DAST)](../../application_security/dast/index.md) | Analyze your running web applications for known vulnerabilities. || [Dependency Scanning](../../application_security/dependency_scanning/index.md) | Analyze your dependencies for known vulnerabilities. || [Static Application Security Testing (SAST)](../../application_security/sast/index.md) | Analyze your source code for known vulnerabilities. |
