chrome-extension-e2e-playwright

Playwright E2E testing for Chrome extensions uses a persistent context with load-extension arguments to load your built extension, ensuring deterministic startup, robust shadow DOM interaction, and reliable diagnostics across environments.

Yes, Playwright supports MV3 extension testing by validating service worker startup, retrieving extension IDs, and interacting with shadow DOM and iframes through a persistent context designed for robust extension behavior.

The best way to retrieve a Chrome extension ID during Playwright testing is to load the extension via a persistent context and smoke-check that the MV3 service worker starts, which allows reliable ID retrieval across different contexts.

Playwright tests loading a Chrome extension may fail if not using a persistent context with proper load-extension arguments; a reference-driven workflow ensures deterministic startup, robust interaction, and reliable diagnostics to prevent loading failures.

Yes, Playwright supports chrome.storage and iframe interaction for MV3 extensions by utilizing a persistent context that ensures stable interaction and diagnosable tests across various extension components and environments.
