+
+AdGuard Home uses [Playwright](https://playwright.dev) for E2E testing. Tests are located in `tests/e2e`.
+
+**Running Tests:**
+- `npm run test:e2e` – run all tests (headless).
+- `npm run test:e2e:interactive` – run tests interactively.
+- `npm run test:e2e:debug` – run tests in debug mode.
+- `npm run test:e2e:codegen` – generate new test code.
+
+**Setup:**
+1. Run `npm install` to install dependencies.
+2. Run `npx playwright install` to set up required browsers.
+
+> **Warning:** Playwright will download and install its own browser binaries for testing, which may differ from the browsers installed on your system.
