Properties

Optional acceptDownloads

acceptDownloads?: boolean

Whether to automatically download all the attachments. Defaults to true where all the downloads are accepted.

Optional baseURL

baseURL?: string

When using page.goto(url[, options]), page.route(url, handler[, options]), page.waitForURL(url[, options]), page.waitForRequest(urlOrPredicate[, options]), or page.waitForResponse(urlOrPredicate[, options]) it takes the base URL in consideration by using the URL() constructor for building the corresponding URL. Unset by default. Examples:

  • baseURL: http://localhost:3000 and navigating to /bar.html results in http://localhost:3000/bar.html
  • baseURL: http://localhost:3000/foo/ and navigating to ./bar.html results in http://localhost:3000/foo/bar.html
  • baseURL: http://localhost:3000/foo (without trailing slash) and navigating to ./bar.html results in http://localhost:3000/bar.html

Optional colorScheme

colorScheme?: "light" | "dark" | "no-preference"

Emulates 'prefers-colors-scheme' media feature, supported values are 'light', 'dark', 'no-preference'. See page.emulateMedia([options]) for more details. Passing null resets emulation to system defaults. Defaults to 'light'.

Optional deviceScaleFactor

deviceScaleFactor?: number

Specify device scale factor (can be thought of as dpr). Defaults to 1. Learn more about emulating devices with device scale factor.

Optional extraHTTPHeaders

Type declaration

  • [key: string]: string

Optional ignoreHTTPSErrors

ignoreHTTPSErrors?: boolean

Whether to ignore HTTPS errors when sending network requests. Defaults to false.

Optional isMobile

isMobile?: boolean

Whether the meta viewport tag is taken into account and touch events are enabled. isMobile is a part of device, so you don't actually need to set it manually. Defaults to false and is not supported in Firefox. Learn more about mobile emulation.

Optional javaScriptEnabled

javaScriptEnabled?: boolean

Whether or not to enable JavaScript in the context. Defaults to true. Learn more about disabling JavaScript.

Optional locale

locale?: string

Specify user locale, for example en-GB, de-DE, etc. Locale will affect navigator.language value, Accept-Language request header value as well as number and date formatting rules. Defaults to the system default locale. Learn more about emulation in our emulation guide.

A list of permissions to grant to all pages in this context. See browserContext.grantPermissions(permissions[, options]) for more details. Defaults to none.

Optional proxy

proxy?: {
    bypass?: string;
    password?: string;
    server: string;
    username?: string;
}

Network proxy settings to use with this context. Defaults to none.

NOTE For Chromium on Windows the browser needs to be launched with the global proxy for this option to work. If all contexts override the proxy, global proxy will be never used and can be any string, for example launch({ proxy: { server: 'http://per-context' } }).

Type declaration

  • Optional bypass?: string

    Optional comma-separated domains to bypass proxy, for example ".com, chromium.org, .domain.com".

  • Optional password?: string

    Optional password to use if HTTP proxy requires authentication.

  • server: string

    Proxy to be used for all requests. HTTP and SOCKS proxies are supported, for example http://myproxy.com:3128 or socks5://myproxy.com:3128. Short form myproxy.com:3128 is considered an HTTP proxy.

  • Optional username?: string

    Optional username to use if HTTP proxy requires authentication.

Optional recordHar

recordHar?: {
    content?: "omit" | "embed" | "attach";
    mode?: "full" | "minimal";
    omitContent?: boolean;
    path: string;
    urlFilter?: string | RegExp;
}

Enables HAR recording for all pages into recordHar.path file. If not specified, the HAR is not recorded. Make sure to await browserContext.close([options]) for the HAR to be saved.

Type declaration

  • Optional content?: "omit" | "embed" | "attach"

    Optional setting to control resource content management. If omit is specified, content is not persisted. If attach is specified, resources are persisted as separate files or entries in the ZIP archive. If embed is specified, content is stored inline the HAR file as per HAR specification. Defaults to attach for .zip output files and to embed for all other file extensions.

  • Optional mode?: "full" | "minimal"

    When set to minimal, only record information necessary for routing from HAR. This omits sizes, timing, page, cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to full.

  • Optional omitContent?: boolean

    Optional setting to control whether to omit request content from the HAR. Defaults to false. Deprecated, use content policy instead.

  • path: string

    Path on the filesystem to write the HAR file to. If the file name ends with .zip, content: 'attach' is used by default.

  • Optional urlFilter?: string | RegExp

    A glob or regex pattern to filter requests that are stored in the HAR. When a baseURL via the context options was provided and the passed URL is a path, it gets merged via the new URL() constructor. Defaults to none.

Optional recordVideo

recordVideo?: {
    dir: string;
    size?: {
        height: number;
        width: number;
    };
}

Enables video recording for all pages into recordVideo.dir directory. If not specified videos are not recorded. Make sure to await browserContext.close([options]) for videos to be saved.

  • Optional size?: {
        height: number;
        width: number;
    }

    Optional dimensions of the recorded videos. If not specified the size will be equal to viewport scaled down to fit into 800x800. If viewport is not configured explicitly the video size defaults to 800x450. Actual picture of each page will be scaled down if necessary to fit the specified size.

    • height: number

      Video frame height.

    • width: number

      Video frame width.

Optional reducedMotion

reducedMotion?: "reduce" | "no-preference"

Emulates 'prefers-reduced-motion' media feature, supported values are 'reduce', 'no-preference'. See page.emulateMedia([options]) for more details. Passing null resets emulation to system defaults. Defaults to 'no-preference'.

Optional screen

        expires: number;
        httpOnly: boolean;

    localStorage to set for context

Optional strictSelectors

strictSelectors?: boolean

If set to true, enables strict selectors mode for this context. In the strict selectors mode all operations on selectors that imply single target DOM element will throw when more than one element matches the selector. This option does not affect any Locator APIs (Locators are always strict). Defaults to false. See Locator to learn more about the strict mode.

Optional viewport

viewport?: ViewportSize

Emulates consistent viewport for each page. Defaults to an 1280x720 viewport. Use null to disable the consistent viewport emulation. Learn more about viewport emulation.

NOTE The null value opts out from the default presets, makes viewport depend on the host window size defined by the operating system. It makes the execution of the tests non-deterministic.
