# Tests and reports in merge requests

GitLab has the ability to test the changes included in a feature branch and display reports
or link to useful information directly from merge requests:

| Feature                                                                                                | Description                                                                                                                                                                                               |

## 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.              |
