The default browser context is accessible via browser.contexts(). Selectors can be used to install custom selector engines. Stock browsers like Google Chrome and Microsoft Edge are suitable for tests that require proprietary media codecs for video playback. For example, if your app prompts you to sign in every week even if you're on the same computer/browser, you'll need to update storageState.json at least this often. If Google Chrome (rather than Chromium) is preferred, a Chrome Canary or Dev Channel build is suggested. Note that Chromium's user data directory is the parent directory of the "Profile Path" seen at chrome://version. Accounts with multi-factor authentication (MFA) cannot be fully automated, and need manual intervention. To make a direct download, we'll use two native NodeJS modules, fs and https, to interact with a filesystem and file download. Dangerous option; use with care. As described in playwright.dev/docs/auth/#lifecycle after creating new page with context.newPage () you should login to the web site manually in the page. For example, locator.waitFor([options]) might fail if the selector doesn't match any nodes during the given timeframe.

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. . Redoing login for every test can slow down test execution. An example of launching a browser executable and connecting to it later: Returns browser name. Path at which to serve the Browser Server. @dgozman any news on that? Any of the methods above to create multiple storage state files would work. For this reason, you should use an unguessable token when using this option. Well occasionally send you account related emails. In that case, you can log into that page once in beforeAll and then use that same page in all the tests. You signed in with another tab or window. 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. Have a question about this project? I can use it to set a port during chromium.launchPersistentContext and the browser does launch with websocket port as well as userDataDirectory. Path to a browser executable to run instead of the bundled one. For security, this defaults to an unguessable string. options? > Additional arguments to pass to the browser instance. Tests written with Playwright execute in isolated clean-slate environments called browser contexts. In either case, the downloads are deleted when the browser context they were created in is closed.#, env? Let's take a look at how we can upload a file using Playwright. User data directories can be used with the browserType.launchPersistentContext(userDataDir[, options]) API. Sometimes you have more than one signed-in user in your end to end tests. userDataDir < Path > Path to a User Data Directory, which stores browser session data like cookies and local storage. Playwright is a cross-broser automation library created by Microsoft. Playwright methods might throw errors if they are unable to fulfill a request. That way you can log in only once and then skip the log in step for all of the tests. playwright-stealth.js This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. const browser = await chromium.launchPersistent('./tmp', options); const . Libraries such as Playwright help speed up processes by opening the web application in a browser and other user interactions such as clicking elements, typing text, and, of course, extracting public data from the web. This defeats the use case that I am trying to achieve. Playwright module provides a method to launch a browser instance. User Data Directory. - Yury Semikhatsky Oct 28, 2021 at 17:44 The Puppeteer and Playwright APIs for handling cookies are slightly different but achieve the same goals.

Does 'user/data/dir' exist? public string UserDataDir { get; set; } Property Value. Page. Node.js version: v13.12.. Browser: Google Chrome. I am hoping that we can add another way to connect. Read more about using Google Chrome and Microsoft Edge.#, chromiumSandbox? Once these steps are executed, the browser context will be authenticated. Persistent authentication can be used to partially automate MFA scenarios. Defaults to false. // Use web socket endpoint later to establish a connection. Declaration. Playwright allows to use a browser in a headless mode (the default mode), which works without the UI. chromium. On most Windows 10 installations, this path resolves to C:\Users\<Current-user . // Here you can add locators and helper methods specific to the admin page. Operating System: Mac. npx playwright install msedge When using the above playwright.config.ts file, Playwright Test uses Microsoft Edge to run your tests, as follows: npx playwright test --headed Use Playwright as a library. args? Closing this context will automatically close the browser. More details for Chromium and Firefox. Cross-language. The following example automates logging into GitHub. Node.js E2E puppeteerTestCafe . This article describes some differences for Linux users. // Runs before each test and signs in each page. // Override storage state, use worker index to look up logged-in info and generate it lazily. Cookies and local storage state can be used across different browsers. Close the browser process on Ctrl-C. Defaults to true.#, handleSIGTERM? Session storage is specific to a particular domain and is not persisted across page loads. 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. Already on GitHub? Logger sink for Playwright logging.#, port? Global setup script from the example above would change like this: By default, Playwright Test runs tests in parallel. Persistent authentication can be used to partially automate MFA scenarios. // Save signed-in state to 'storageState.json'. 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. Playwright does not provide API to persist session storage, but the following snippet can be used to save/load session storage. We would like to make non-persistent contexts equally good by providing means to save/restore the state you'd like to be persisted. Cookies and local storage state can be used across different browsers. We will use this demo form from W3 school to demonstrate file attachments in the scope of the HTML forms. If this option is true, the headless option will be set false.#, downloadsPath? // Extend base test by providing "adminPage" and "userPage". Playwright: [] : userDataDir `browserType.launch`. Defaults to true.#, headless? 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). Selenium2020()PlaywrightMicrosoft PlaywrightC# 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. New browser contexts can load existing authentication state. // Create a unique username for each worker. BrowserType provides methods to launch a specific browser instance or connect to an existing one. Something like chromium.launchPersistentContextServer which: Any pointers on where to look for design docs or how to achieve this would be really helpful and much appreciated. Ideally, Playwright would detect that the requested context is already active in an existing Chromium process and connect to it automatically. Get started Star 42k+ Any browser Any platform One API Cross-browser. Also, in the interest of sharing use cases: The wsEndpoint functionality mentioned by @VikramTiwari would be nice. So maybe that's the "lowest effort" solution for satisfying these varied use cases after all. Added in: v1.15#. /** @type {import('@playwright/test').Page} */, // Get session storage and store as env variable, // Execute login steps manually in the browser window. Regardless, I hope this workaround helps someone out there! privacy statement. Web apps use cookie-based or token-based authentication, where authenticated state is stored as cookies or in local storage. Determine the system cache dir. Any process or web page (including those running in Playwright) with knowledge of the wsPath can take control of the OS user. Sign in The Playwright API can automate interaction from a login form. User data directories are specific to browser types and cannot be shared across browser types. If your web application supports signing in via API, you can use APIRequestContext to simplify sign in flow. One of the main features of Playwright is that it can automate Chromium, Webkit, and Firefox browsers with a single API. This helper works with a browser out of the box with no additional tools required to install. to your account. Extra: Trying to re-use Firebase Auth sessions.
