But from this browser, I can't get the existing contexts and can only create new incognito contexts. These classes are available via playwright.errors. Close the browser process on SIGTERM. 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. If specified, accepted downloads are downloaded into this directory. This eliminates the need to login in every context and speeds up test execution. type: <APIRequest> Exposes API that can be used for the Web API testing. You can now pass --remote-debugging-port as an argument and use connectOverCDP. This object can be used to launch or connect to Firefox, returning instances of Browser. If this option is true, the headless option will be set false.#, downloadsPath? Redoing login for every test can slow down test execution. Let's take a look at how we can upload a file using Playwright. Playwright is a Go library to automate Chromium, Firefox and WebKit with a single API. Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. If desired, the script could omit the step of closing the context/browser. The goal is to launch a browser on server that's always up. We will upload a previous screenshot we've made using Playwright and will create a new one: const playwright = require('playwright'); (async () => { Just in case it helps others, I found a workaround which is more complex but probably ends up being more performant. Defaults to false.#, logger? 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. window.sessionStorage.setItem(key, value); BrowserType.LaunchPersistentContextAsync(userDataDir, options). launchPersistentContext (userDataDir, {headless: false . The following is a typical example of using Playwright to drive automation: This object can be used to launch or connect to Chromium, returning instances of Browser. You can also consume Playwright as a library, as shown in the following code. Playwright can be used to automate scenarios that require authentication. The list of Chromium flags can be found here.#, channel? // Tell all tests to load signed-in state from 'storageState.json'. Well occasionally send you account related emails. [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`. Cross-platform. It supports all modern rendering engines including Chromium, WebKit, and Firefox. public string UserDataDir { get; set; } Property Value. However, periodically, you may need to update the storageState.json file if your app requires you to re-authenticate after some amount of time. Note: This guide covers cookie/token-based authentication (logging in via the app UI). Added in: v1.15#. New browser contexts can load existing authentication state. If you reuse a single signed-in state for all your tests, this usually leads to the same account being signed in from multiple tests at the same time. Does 'user/data/dir' exist? This is ~/.cache, unless overridden by $XDG_CACHE_HOME. // Create a new context with the saved storage state. Thanks folks! Requires playwright or playwright-core package version ^1 to be installed: npm i playwright@^1.18 --save or npm i playwright-core@^1.18 --save playwright.request Added in: v1.16. 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 comes with built-in waiting mechanisms on navigation and page interactions. Redoing login for every test can slow down test execution. Cookies and local storage state can be used across different browsers. This content moved to https://chromium.googlesource.com/chromium/src/+/HEAD/docs/user_data_dir.md.https://chromium.googlesource.com/chromium/src . Enable Chromium sandboxing. Path to a User Data Directory. The way to achieve this would be to use both wsEndpoint and userDataDir. If this behavior is undesirable for your application, you can sign in with a different account in each worker process created by Playwright Test. A practical guide to the Web Storage APIs, sessionStorage and localStorage. If an array is given, then filters out the given default arguments. Use case: To mitigate that, reuse existing authentication state instead. Playwright methods might throw errors if they are unable to fulfill a request. Playwright is an open-source NodeJS framework for browser automation. See Working with selectors for more information. Sometimes you have more than one signed-in user in your end to end tests. The following is a typical example of using Playwright to drive automation: This method attaches Playwright to an existing browser instance. Global setup script from the example above would change like this: By default, Playwright Test runs tests in parallel. Headless execution is supported for all the browsers on all platforms. Playwright does not provide API to persist session storage, but the following snippet can be used to save/load session storage. Pass 0 to disable timeout.#, tracesDir? Learn more about the Firefox user preferences at about:config.#, handleSIGHUP? Any of the methods above to create multiple storage state files would work. More details for Chromium and Firefox. Call into Lighthouse Close the context Then use this helper from any of your tests. 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). The following code snippet retrieves state from an authenticated context and creates a new context with that state. Defaults to 0 that picks any available port.#, timeout? Also, in the interest of sharing use cases: The wsEndpoint functionality mentioned by @VikramTiwari would be nice. 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. For HTTP authentication use Browser.NewContextAsync(options). Merged. By clicking Sign up for GitHub, you agree to our terms of service and // This new "test" can be used in multiple test files, and each of them will get the fixtures. Playwright Version: 1.8.0. If you can log in once and commit the storageState.json into the repository, you won't need the global setup at all, just specify the storageState.json in Playwright Config as above and it'll be picked up. Use browserType.launchPersistent instead As the error describes, you should use .launchPersistent instead of .launch Most likely on one of the computers you have an older version of playwright (pre-#974) jozsi on 17 Feb 2020 Note that Playwright only works with the bundled Chromium, Firefox or WebKit, use at your own risk.#, firefoxUserPrefs? We can use cookies and Web Storage APIs through Puppeteer and Playwright to set test state and speed up test suites. An upgrade as described in this issue would allow us to use a user directory from multiple processes simultaneously, right? From what I have understood: use launchPersistentContext to launch with userDataDir but it doesn't allow wsEndpoint; use launchServer to launch with wsEndpoint but it doesn't allow . At this point, I can use the webSocketDebuggerUrl from localhost:12345/json/version to connect to the browser. This is not our current priority, so no progress just yet. Register global setup script in the Playwright configuration file: Tests start already authenticated because we specify storageState that was populated by global setup. Supported values are "chrome", "chrome-beta", "chrome-dev", "chrome-canary", "msedge", "msedge-beta", "msedge-dev", "msedge-canary". /** @type {import('@playwright/test').PlaywrightTestConfig} */. Dangerous option; use with care. Cookies and local storage state can be used across different browsers. Connecting over the Chrome DevTools Protocol is only supported for Chromium-based browsers. . Accounts with multi-factor authentication (MFA) cannot be fully automated, and need manual intervention. Web apps use cookie-based or token-based authentication, where authenticated state is stored as cookies or in local storage. Session storage is specific to a particular domain and is not persisted across page loads. This would allow subsequent Playwright processes to connect to the existing Chromium instance without needing to perform any kind of application startup. // Use adminPage and userPage fixtures in the test. - Yury Semikhatsky Oct 28, 2021 at 17:44 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. I want to ensure that I can sign in to that browser and it will retain my credentials. An example of launching a browser executable and connecting to it later: Returns browser name. Web apps use cookie-based or token-based authentication, where authenticated state is stored as cookies or in local storage. The following code snippet retrieves state from an authenticated context and creates a new context with that state. Note that persistent authentication is not suited for CI environments since it relies on a disk location. Further reading The official MDN docs for cookies. Dangerous option; use with care. Defaults to false.#, devtools? Since these are baked into the tool itself, it is good to get familiar with the logic behind them, as well as how to override the default behaviour when necessary. Launches browser that uses persistent storage located at userDataDir and returns the only context. 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. P.S. > Firefox user preferences. I'd love this functionality, as well. . For example: 'chromium', 'webkit' or 'firefox'. For certain types of errors Playwright uses specific error classes. Installation go get github.com/mxschmitt/playwright-go Capabilities const browser = await chromium.launchPersistent('./tmp', options); const context = await browser.newContext(); . When configuring these policies, you can use variables instead of hard-coded paths. Playwright . Playwright module provides a method to launch a browser instance. That way you can log in only once and then skip the log in step for all of the tests. These seems like design decisions and I am sure they are valid ones. Page.waitForSelector (Showing top 15 results out of 315) puppeteer ( npm) Page waitForSelector. This is great for scripting. 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. Persistent authentication can be used to partially automate MFA scenarios. Read more about using Google Chrome and Microsoft Edge.#, chromiumSandbox? This is ~/.config, unless overridden by $XDG_CONFIG_HOME. 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. 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. Node.js version: v13.12.. Browser: Google Chrome. > If true, Playwright does not pass its own configurations args and only uses the ones from args.

Regardless, I hope this workaround helps someone out there! Chromium-only Whether to auto-open a Developer Tools panel for each tab. Otherwise, temporary directory is created and is deleted when browser is closed. Pass an empty string to use a temporary directory instead. type: <Selectors> Tests written with Playwright execute in isolated clean-slate environments called browser contexts. Explicit waits Explicit waits are a type of smart wait we invoke explicitly as part of our script. Although discouraged, sometimes it is necessary to sacrifice the isolation and run a number of tests in the same page. If executablePath is a relative path, then it is resolved relative to the current working directory. Defaults to true.#, handleSIGINT? Determine the system cache dir. More details for Chromium and Firefox. Closing this context will automatically close the browser. 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. For this reason, you should use an unguessable token when using this option. > Additional arguments to pass to the browser instance. Also, we're going to use page.$eval function to get our desired element. We will use this demo form from W3 school to demonstrate file attachments in the scope of the HTML forms. dgozman mentioned this issue Feb 2, 2021. docs: note that user data dir is a parent of profile path #5262. The Playwright API can automate interaction from a login form. If your web application supports signing in via API, you can use APIRequestContext to simplify sign in flow. This object can be used to launch or connect to WebKit, returning instances of Browser. browserType.launchPersistentContext(userDataDir[, options]), Avoiding multiple sessions per account at a time, Reuse the signed in page in multiple tests. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Page. playwright.selectors Added in: v1.8. Launch a persistent context with the user data directory and login the MFA account.
