Playwright module provides a method to launch a browser instance. The following is a typical example of using Playwright to drive automation:
const { chromium, firefox, webkit } = require('playwright');
(async () => {
const browser = await chromium.launch(); // Or 'firefox' or 'webkit'.
const page = await browser.newPage();
await page.goto('http://example.com');
// other actions...
await browser.close();
})(); This object can be used to launch or connect to Chromium, returning instances of Browser.
Usage
playwright.chromium
Type
Returns a dictionary of devices to be used with browser.newContext() or browser.newPage().
const { webkit, devices } = require('playwright');
const iPhone = devices['iPhone 6'];
(async () => {
const browser = await webkit.launch();
const context = await browser.newContext({
...iPhone
});
const page = await context.newPage();
await page.goto('http://example.com');
// other actions...
await browser.close();
})(); Usage
playwright.devices
Type
Playwright methods might throw errors if they are unable to fulfill a request. For example, locator.waitFor() might fail if the selector doesn't match any nodes during the given timeframe.
For certain types of errors Playwright uses specific error classes. These classes are available via playwright.errors.
An example of handling a timeout error:
try {
await page.locator('.foo').waitFor();
} catch (e) {
if (e instanceof playwright.errors.TimeoutError) {
// Do something if this is a timeout.
}
} Usage
playwright.errors
Type
TimeoutError function
A class of TimeoutError.
This object can be used to launch or connect to Firefox, returning instances of Browser.
