Automate web testing by combining Playwright for e2e testing across browsers and Vitest for unit and integration testing to ensure full component coverage. This approach validates user journeys and individual modules simultaneously to improve application robustness.

Load testing with k6 simulates high traffic to identify performance bottlenecks in web applications. It generates concurrent virtual users to stress test server endpoints, helping developers pinpoint scalability limits and optimize response times under heavy load.

Playwright and Vitest support visual regression testing to ensure UI consistency and accessibility testing for WCAG compliance. They automate screenshot comparisons and DOM evaluation to detect visual defects and verify web applications are usable for all users.

Security testing covers vulnerabilities like XSS and SQL injection by automating payload injection and response validation. It scans web application inputs and outputs to detect common security flaws, ensuring malicious code execution and database breaches are prevented.

Playwright, Vitest, and k6 must be installed and configured correctly before running web tests. These dependencies provide the execution environments required to run unit, e2e, and load testing scripts successfully from your command line.

Execute unit tests by running `npx vitest run` and end-to-end tests with `npx playwright test` in your terminal. These commands trigger the respective frameworks to automatically scan test files and output pass or fail results.
