Sourced from playwright's releases.

v1.51.0

Highlights

• New option indexed_db for browserContext.storage_state() allows to save and restore IndexedDB contents. Useful when your application uses IndexedDB API to store authentication tokens, like Firebase Authentication.

  Here is an example following the authentication guide:

  # Save storage state into the file. Make sure to include IndexedDB.
  storage = context.storage_state(path="state.json", indexed_db=True)
  Create a new context with the saved storage state.
  context = browser.new_context(storage_state="state.json")

• New option visible for locator.filter() allows matching only visible elements.

  # Ignore invisible todo items.
  todo_items = page.get_by_test_id("todo-item").filter(visible=True)
  # Check there are exactly 3 visible ones.
  expect(todo_items).to_have_count(3)

• New option contrast for methods page.emulate_media() and browser.new_context() allows to emulate the prefers-contrast media feature.

• New option fail_on_status_code makes all fetch requests made through the APIRequestContext throw on response codes other than 2xx and 3xx.
