How did you run UI tests on CI? What did you use?

The following approaches and tools are commonly used to run UI tests on CI:

• Integration with CI/CD systems: Jenkins, GitLab CI, GitHub Actions, TeamCity, etc.
• UI testing frameworks: Selenium WebDriver, Cypress, Playwright.
• Running tests in headless browsers (e.g., Chrome Headless) for faster execution and convenience on the server.
• Using Docker containers for environment isolation and reproducibility.
• Parallel test execution to reduce runtime.

Example: a Jenkins pipeline is configured to run a script with UI tests on Selenium in headless mode upon a push to the repository; test results are collected and displayed in reports.

It is important to ensure the stability of the testing environment, proper dependency management, and timely cleanup of artifacts.
