Browser

A Browser is created via BrowserType.launch(). An example of using a Browser to create a Page:

import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      BrowserType firefox = playwright.firefox()
      Browser browser = firefox.launch();
      Page page = browser.newPage();
      page.navigate('https://example.com');
      browser.close();
    }
  }
}

Methods

browserType

Added in: v1.23

browser.browserType

Get the browser type (chromium, firefox or webkit) that the browser belongs to.

Usage

Browser.browserType();

Returns

BrowserType #

close

Added in: v1.8

browser.close

In case this browser is obtained using BrowserType.launch(), closes the browser and all of its pages (if any were opened).

In case this browser is connected to, clears all created contexts belonging to this browser and disconnects from the browser server.

note

This is similar to force quitting the browser. Therefore, you should call BrowserContext.close() on any BrowserContext's you explicitly created earlier with Browser.newContext() before calling Browser.close().

The Browser object itself is considered to be disposed and cannot be used anymore.

Usage

Browser.close();
Browser.close(options);

Arguments

options Browser.CloseOptions (optional)
- setReason String (optional) Added in: v1.40#
  
  The reason to be reported to the operations interrupted by the browser closure.

Returns

void #

contexts

Added in: v1.8

browser.contexts

Returns an array of all open browser contexts. In a newly created browser, this will return zero browser contexts.

Usage

Browser browser = pw.webkit().launch();
System.out.println(browser.contexts().size()); // prints "0"
BrowserContext context = browser.newContext();
System.out.println(browser.contexts().size()); // prints "1"

Returns

List<BrowserContext>#

isConnected

Added in: v1.8

browser.isConnected

Indicates that the browser is connected.

Usage

Browser.isConnected();

Returns

boolean #

newBrowserCDPSession

Added in: v1.11

browser.newBrowserCDPSession

note

CDP Sessions are only supported on Chromium-based browsers.

Returns the newly created browser session.

Usage

Browser.newBrowserCDPSession();

Returns

CDPSession #

newContext

Added in: v1.8

browser.newContext

Creates a new browser context. It won't share cookies/cache with other browser contexts.

note

If directly using this method to create BrowserContexts, it is best practice to explicitly close the returned context via BrowserContext.close() when your code is done with the BrowserContext, and before calling Browser.close(). This will ensure the context is closed gracefully and any artifacts—like HARs and videos—are fully flushed and saved.

Usage

Browser browser = playwright.firefox().launch();  // Or 'chromium' or 'webkit'.
// Create a new incognito browser context.
BrowserContext context = browser.newContext();
// Create a new page in a pristine context.
Page page = context.newPage();
page.navigate('https://example.com');

// Graceful close up everything
context.close();
browser.close();

  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' } }).
- setRecordHarContent enum HarContentPolicy { OMIT, EMBED, ATTACH } (optional)#
  
  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 and all of these files are archived along with the HAR file. Defaults to embed, which stores content inline the HAR file as per HAR specification.
- setRecordHarMode enum HarMode { FULL, MINIMAL } (optional)#
  
  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.

    Video frame width.
  - setHeight int
    
    Video frame height.

- setReducedMotion null|enum ReducedMotion { REDUCE, NO_PREFERENCE } (optional)#
  
  Emulates 'prefers-reduced-motion' media feature, supported values are 'reduce', 'no-preference'. See Page.emulateMedia() for more details. Passing null resets emulation to system defaults. Defaults to 'no-preference'.
- setScreenSize ScreenSize (optional)#
  - setWidth int
    
    page width in pixels.
  - setHeight int
    
    page height in pixels.

  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.
- setTimezoneId String (optional)#
  
  Changes the timezone of the context. See ICU's metaZones.txt for a list of supported timezone IDs. Defaults to the system timezone.
- setUserAgent String (optional)#
  
  Specific user agent to use in this context.
- setViewportSize null|ViewportSize (optional)#
  - setWidth int
    
    page width in pixels.
  - setHeight int
    
    page height in pixels.
  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.

browser.newPage

Creates a new page in a new browser context. Closing this page will close the context as well.
