@replayio/playwright

Plugin to record your Playwright tests with Replay.

Check out the "Recording Automated Tests Guide" to get started.

Use with action-playwright to automatically upload replays of failed tests.

Installation

npm i -D @replayio/playwright

Configuration

import { PlaywrightTestConfig, devices } from "@playwright/test";
import { devices as replayDevices } from "@replayio/playwright";

const config: PlaywrightTestConfig = {
  projects: [
    {
      name: "replay-chromium",
      use: { ...replayDevices["Replay Chromium"] },
    },
    {
      name: "firefox",
      use: { ...devices["Desktop Firefox"] },
    },
    {
      name: "chromium",
      use: { ...devices["Desktop Chromium"] },
    },
  ],
};
export default config;

Runtime Configuration

  • Use the --project flag to select a project and specified Replay Browser to record.
  • To capture and report metadata, use --reporter=@replayio/playwright/reporter,line
npx playwright test
--project replay-chromium
--reporter=@replayio/playwright/reporter,line

Exports

  • devices - Object of configurations suitable for using with @playwright/test. Currently only supports the "Replay Chromium" configuration. If the configuration isn't supported on the current platform, a warning is emitted and the executablePath will be undefined.
  • getExecutablePath() - Returns the path to the Replay Browser. If the current platform isn't supported, undefined is returned.
  • getMetadataFilePath(workerIndex: number = 0) - Returns the path of a worker-specific metadata file keyed by the workerIndex. The file path will be within the RECORD_REPLAY_DIRECTORY.

Parallel runs on CI

If you have a large test suite, you might choose to split your test suite up and run them in parallel across multiple machines but still treat them as a single suite. By default, @replayio/playwright will generate a UUID for the suite and store it in the recording metadata under test.run.id but in this case each machine will have its own id.

In order to link these independently ran tests together, you can generate your own UUID and set it in the RECORD_REPLAY_TEST_RUN_ID environment variable and it will be used instead of generating a value.
