I'd love to have this feature as well and I am ready to help too :). The Playwright API can automate interaction from a login form. If this behavior is undesirable for your application, you can sign in with a different account in each worker process created by Playwright Test. Returns a dictionary of devices to be used with browser.newContext([options]) or browser.newPage([options]). // Make sure we are not using any other storage state. So we can use the href value of this button to make a direct download instead of using Playwright's click simulation. If Google Chrome (rather than Chromium) is preferred, a Chrome Canary or Dev Channel build is suggested. To make a direct download, we'll use two native NodeJS modules, fs and https, to interact with a filesystem and file download. If true, Playwright does not pass its own configurations args and only uses the ones from args. Have a question about this project? For example: 'chromium', 'webkit' or 'firefox'. This article explains everything about Playwright and how it can be used for automation and even web scraping. // adminContext and all pages inside, including adminPage, are signed in as "admin". Enable Chromium sandboxing. // Here you can add locators and helper methods specific to the admin page. Returns the persistent browser context instance. to your account. Register global setup script in the Playwright configuration file: Tests start already authenticated because we specify storageState that was populated by global setup. You can use ignoreDefaultArgs to filter out --mute-audio from default arguments: Chromium-only Playwright can also be used to control the Google Chrome or Microsoft Edge browsers, but it works best with the version of Chromium it is bundled with. Cookies and local storage state can be used across different browsers. The list of Chromium flags can be found here.#, channel? If specified, traces are saved into this directory.#, wsPath? Playwright is an open-source NodeJS framework for browser automation. Does 'user/data/dir' exist? const browser = await chromium.launchPersistent('./tmp', options); const context = await browser.newContext(); . Once these steps are executed, the browser context will be authenticated. A practical guide to the Web Storage APIs, sessionStorage and localStorage. Page. Explicit waits Explicit waits are a type of smart wait we invoke explicitly as part of our script. Connecting over the Chrome DevTools Protocol is only supported for Chromium-based browsers. // Save signed-in state to 'storageState.json'. browserType.connect(wsEndpoint[, options]), browserType.connectOverCDP(endpointURL[, options]), browserType.launchPersistentContext(userDataDir[, options]), page.waitForRequest(urlOrPredicate[, options]), page.waitForResponse(urlOrPredicate[, options]), browserContext.grantPermissions(permissions[, options]), browserType.connectOverCDP(endpointURL, options), browserType.launchPersistentContext(userDataDir, options). This object can be used to launch or connect to WebKit, returning instances of Browser. Use executablePath option with extreme caution. The following is a typical example of using Playwright to drive automation: This method attaches Playwright to an existing browser instance. There is no guarantee it will work with any other version. Playwright comes with built-in waiting mechanisms on navigation and page interactions. So maybe that's the "lowest effort" solution for satisfying these varied use cases after all. Extra: Trying to re-use Firebase Auth sessions. A path where Playwright expects to find a bundled browser executable. Playwright provides browserContext.storageState([options]) method that can be used to retrieve storage state from authenticated contexts and then create new contexts with prepopulated state. This helper works with a browser out of the box with no additional tools required to install. launchPersistentContext (userDataDir, {headless: false . What is Playwright? window.sessionStorage.setItem(key, value); BrowserType.LaunchPersistentContextAsync(userDataDir, options). Playwright methods might throw errors if they are unable to fulfill a request. To mitigate that, reuse existing authentication state instead. Tests written with Playwright execute in isolated clean-slate environments called browser contexts. Returns the browser app instance. For certain types of errors Playwright uses specific error classes. In short, here's how it works: While this does work, I think the "default" behavior of Playwright should be to allow connecting to the same user directory from multiple processes. Accounts with multi-factor authentication (MFA) cannot be fully automated, and need manual intervention. Path at which to serve the Browser Server. [Question] Is it possible to customize both user-data-dir and websocket port, // PLAYWRIGHT_CHROMIUM_DEBUG_PORT=12345 parent.js, // replace with webSocketDebuggerUrl from localhost:12345/json/version, `ws://localhost:12345/devtools/browser/489bad93-902d-4f2d-b8ad-0be5868d9313`. You will see something like this: Run the same script, but with headless: true, The output is the same as before authorization: response.request ().headers does not contain cookies in both headless: false and . const browser = await chromium.launchPersistent('./tmp', options); const . Playwright provides a way to reuse the signed-in state in the tests. Port to use for the web socket. You can also consume Playwright as a library, as shown in the following code. // Runs before each test and signs in each page. Session storage is specific to a particular domain and is not persisted across page loads. > Specify environment variables that will be visible to the browser. Chromium-only Whether to auto-open a Developer Tools panel for each tab. Reuse user data directory to run automation scenarios. Added in: v1.15#. \ nodejs \ telegram \ node_modules \ playwright-core \ lib \ server \ chromium.js: 44:19) You signed in with another tab or window. . Redoing login for every test can slow down test execution. Best JavaScript code snippets using puppeteer. This eliminates the need to login in every context and speeds up test execution. Launches browser server that client can connect to. // Extend base test by providing "adminPage" and "userPage". playwright.firefox Added in: v1.8. I have time to contribute a fix but I don't fully understand why browser server instances don't have access to the pre-existing contexts and why are they limited to just incognito contexts. Even after I restart my VM, the browser will retain all the user preferences, cookies etc. Headless execution is supported for all the browsers on all platforms. Otherwise, temporary directory is created and is deleted when browser is closed. New browser contexts can load existing authentication state. Redoing login for every test can slow down test execution. Stock browsers like Google Chrome and Microsoft Edge are suitable for tests that require proprietary media codecs for video playback. // Here you can add locators and helper methods specific to the user page. If executablePath is a relative path, then it is resolved relative to the current working directory. You can achieve that via logging in for these users multiple times in globalSetup and saving that state into different files. Supported values are "chrome", "chrome-beta", "chrome-dev", "chrome-canary", "msedge", "msedge-beta", "msedge-dev", "msedge-canary". You can connect to it via browserType.connect(wsEndpoint[, options]), which requires the major/minor client/server version to match (1.2.3 is compatible with 1.2.x). It supports all modern rendering engines including Chromium, WebKit, and Firefox. Playwright puppeteer . This article describes some differences for Linux users. playwright.request Added in: v1.16. If your use case is similar to mine (i.e. Defaults to true unless the devtools option is true.#, ignoreDefaultArgs? Playwright module provides a method to launch a browser instance. These classes are available via playwright.errors. Closing this context will automatically close the browser. public string UserDataDir { get; set; } Property Value. Cookies and local storage state can be used across different browsers. In either case, the downloads are deleted when the browser context they were created in is closed.#, env? Set the UserDataDir policy to $ {local_app_data}\Edge\Profile. Playwright does not provide API to persist session storage, but the following snippet can be used to save/load session storage. Call into Lighthouse Close the context Then use this helper from any of your tests. We would like to make non-persistent contexts equally good by providing means to save/restore the state you'd like to be persisted. Defaults to false.#, devtools? Note that persistent authentication is not suited for CI environments since it relies on a disk location. For example, locator.waitFor([options]) might fail if the selector doesn't match any nodes during the given timeframe. Note: This guide covers cookie/token-based authentication (logging in via the app UI). playwright.selectors Added in: v1.8. chromium. // Tell all tests to load signed-in state from 'storageState.json'. They depend on your application's authentication model: some apps might require both cookies and local storage. Persistent authentication can be used to partially automate MFA scenarios. Node.js version: v13.12.. Browser: Google Chrome. Any of the methods above to create multiple storage state files would work. The following example automates logging into GitHub. Logger sink for Playwright logging.#, port? Regardless, I hope this workaround helps someone out there! enables usage of user's data directory connects using websocket port allows new connections through websocket port/URL can utilize both normal and incognito contexts can see and use existing contexts for the connected browser Start a browserServer and save the resulting wsEndpoint into a file. At the moment, it seems like we need to choose between having a user directory and only being able to automate from a single process OR not having a user directory but being able to automate from multiple processes simultaneously. At this point, I can use the webSocketDebuggerUrl from localhost:12345/json/version to connect to the browser. This isolation model improves reproducibility and prevents cascading test failures. The following example automates logging into GitHub. Playwright Version: 1.8.0. // userContext and all pages inside, including userPage, are signed in as "user". // Create a unique username for each worker. However, for our use case, it's not strictly necessary (or even desirable, as it complicates things). /** @type {import('@playwright/test').PlaywrightTestConfig} */. After that you can specify the user to use for each test file or each test group: If you need to test how multiple authenticated roles interact together, use multiple BrowserContexts and Pages with different storage states in the same test.
