/**
 * - extends: [EventEmitter]
 *
 * Page provides methods to interact with a single tab in a [Browser], or an
 * [extension background page](https://developer.chrome.com/extensions/background_pages) in Chromium. One [Browser]
 * instance might have multiple [Page] instances.
 *
 * This example creates a page, navigates it to a URL, and then saves a screenshot:
 *
 * ```js
 * const { webkit } = require('playwright');  // Or 'chromium' or 'firefox'.
 *
 * (async () => {
 *   const browser = await webkit.launch();
 *   const context = await browser.newContext();
 *   const page = await context.newPage();
 *   await page.goto('https://example.com');
 *   await page.screenshot({path: 'screenshot.png'});
 *   await browser.close();
 * })();
 * ```
 *
 * The Page class emits various events (described below) which can be handled using any of Node's native
 * [`EventEmitter`](https://nodejs.org/api/events.html#events_class_eventemitter) methods, such as `on`, `once` or
 * `removeListener`.
 *
 * This example logs a message for a single page `load` event:
 *
 * ```js
 * page.once('load', () => console.log('Page loaded!'));
 * ```
 *
 * To unsubscribe from events use the `removeListener` method:
 *
 * ```js
 * function logRequest(interceptedRequest) {
 *   console.log('A request was made:', interceptedRequest.url());
 * }
 * page.on('request', logRequest);
 * // Sometime later...
 * page.removeListener('request', logRequest);
 * ```
 *

   * await page.goto('https://example.com');
   * await browser.close();
   * ```
   *
   * It is possible to examine the request to decide the route action. For example, mocking all requests that contain some
   * post data, and leaving all other requests as is:
   *
   * ```js
   * await page.route('/api/**', route => {

   * Routing provides the capability to modify network requests that are made by any page in the browser context. Once route

   * window.navigator.serviceWorker);`
   *
   * An example of a naive handler that aborts all image requests:
   *
   * ```js
   * const context = await browser.newContext();
   * await context.route('**\/*.{png,jpg,jpeg}', route => route.abort());
   * const page = await context.newPage();
   * await page.goto('https://example.com');
   * await browser.close();
   * ```

   * ```js
   * const context = await browser.newContext();
   * await context.route(/(\.png$)|(\.jpg$)/, route => route.abort());
   * const page = await context.newPage();
   * await page.goto('https://example.com');
   * await browser.close();
   * ```
   *
   * It is possible to examine the request to decide the route action. For example, mocking all requests that contain some
   * post data, and leaving all other requests as is:
   *
   * ```js
   * await context.route('/api/**', route => {
   *   if (route.request().postData().includes('my-string'))
   *     route.fulfill({ body: 'mocked-data' });

 *
 * ```js
 * const hrefElement = await page.$('a');
 * await hrefElement.click();
 * ```
 *
 * ElementHandle prevents DOM element from garbage collection unless the handle is disposed with
 * [jsHandle.dispose()](https://playwright.dev/docs/api/class-jshandle#js-handle-dispose). ElementHandles are auto-disposed
 * when their origin frame gets navigated.
 *
 * ElementHandle instances can be used as an argument in
 * [page.$eval(selector, pageFunction[, arg, options])](https://playwright.dev/docs/api/class-page#page-eval-on-selector)
 * and [page.evaluate(pageFunction[, arg])](https://playwright.dev/docs/api/class-page#page-evaluate) methods.
 *
 * > NOTE: In most cases, you would want to use the [Locator] object instead. You should only use [ElementHandle] if you
 * want to retain a handle to a particular DOM Node that you intend to pass into
 * [page.evaluate(pageFunction[, arg])](https://playwright.dev/docs/api/class-page#page-evaluate) as an argument.
 *
 * The difference between the [Locator] and ElementHandle is that the ElementHandle points to a particular element, while
 * [Locator] captures the logic of how to retrieve an element.
 *
 * In the example below, handle points to a particular DOM element on page. If that element changes text or is used by
 * React to render an entirely different component, handle is still pointing to that very DOM element. This can lead to
 * unexpected behaviors.
 *
 * ```js
 * const handle = await page.$('text=Submit');
 * // ...
 * await handle.hover();
 * await handle.click();
 * ```
 *
 * With the locator, every time the `element` is used, up-to-date DOM element is located in the page using the selector. So
 * in the snippet below, underlying DOM element is going to be located twice.
 *
 * ```js
 * const locator = page.locator('text=Submit');
 * // ...
 * await locator.hover();
 * await locator.click();
 * ```

/**
 * Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any
 * given moment. Locator can be created with the
 * [page.locator(selector)](https://playwright.dev/docs/api/class-page#page-locator) method.
 *
 * ```js
 * const locator = page.locator('text=Submit');
 * await locator.click();
 * ```
 *
 * The difference between the Locator and [ElementHandle] is that the latter points to a particular element, while Locator
 * captures the logic of how to retrieve that element.
 *
 * In the example below, handle points to a particular DOM element on page. If that element changes text or is used by
 * React to render an entirely different component, handle is still pointing to that very DOM element. This can lead to
 * unexpected behaviors.
 *
 * ```js
 * const handle = await page.$('text=Submit');
 * // ...
 * await handle.hover();
 * await handle.click();
 * ```
 *
 * With the locator, every time the `element` is used, up-to-date DOM element is located in the page using the selector. So
 * in the snippet below, underlying DOM element is going to be located twice.
 *
 * ```js
 * const locator = page.locator('text=Submit');
 * // ...
 * await locator.hover();
 * await locator.click();
 * ```
 *
 * **Strictness**
 *
 * Locators are strict. This means that all operations on locators that imply some target DOM element will throw if more
 * than one element matches given selector.
 *
 * ```js
 * // Throws if there are several buttons in DOM:
 * await page.locator('button').click();
 *
 * // Works because we explicitly tell locator to pick the first element:
 * await page.locator('button').first().click();
 *
 * // Works because count knows what to do with multiple matches:
 * await page.locator('button').count();

 *
 * Accessibility is a very platform-specific thing. On different platforms, there are different screen readers that might

 *
 * Rendering engines of Chromium, Firefox and WebKit have a concept of "accessibility tree", which is then translated into
 * different platform-specific APIs. Accessibility namespace gives access to this Accessibility Tree.
 *
 * Most of the accessibility tree gets filtered out when converting from internal browser AX Tree to Platform-specific
 * AX-Tree or by assistive technologies themselves. By default, Playwright tries to approximate this filtering, exposing

/**
 * Playwright has **experimental** support for Android automation. This includes Chrome for Android and Android WebView.
 *
 * *Requirements*
 * - Android device or AVD Emulator.
 * - [ADB daemon](https://developer.android.com/studio/command-line/adb) running and authenticated with your device.
 *   Typically running `adb devices` is all you need to do.
 * - [`Chrome 87`](https://play.google.com/store/apps/details?id=com.android.chrome) or newer installed on the device
 * - "Enable command line on non-rooted devices" enabled in `chrome://flags`.
 *
 * *Known limitations*
 * - Raw USB operation is not yet supported, so you need ADB.
 * - Device needs to be awake to produce screenshots. Enabling "Stay awake" developer mode will help.
 * - We didn't run all the tests against the device, so not everything works.
 *
 * *How to run*
 *
 * An example of the Android automation script would be:
 *
 * ```js
 * const { _android: android } = require('playwright');
 *
 * (async () => {
 *   // Connect to the device.
 *   const [device] = await android.devices();
 *   console.log(`Model: ${device.model()}`);
 *   console.log(`Serial: ${device.serial()}`);
 *   // Take screenshot of the whole device.
 *   await device.screenshot({ path: 'device.png' });
 *
 *   {
 *     // --------------------- WebView -----------------------
 *
 *     // Launch an application with WebView.
 *     await device.shell('am force-stop org.chromium.webview_shell');
 *     await device.shell('am start org.chromium.webview_shell/.WebViewBrowserActivity');
 *     // Get the WebView.
 *     const webview = await device.webView({ pkg: 'org.chromium.webview_shell' });
 *
 *     // Fill the input box.
 *     await device.fill({ res: 'org.chromium.webview_shell:id/url_field' }, 'github.com/microsoft/playwright');
 *     await device.press({ res: 'org.chromium.webview_shell:id/url_field' }, 'Enter');
 *
 *     // Work with WebView's page as usual.
 *     const page = await webview.page();
 *     await page.waitForNavigation({ url: /.*microsoft\/playwright.*\/ });
 *     console.log(await page.title());
 *   }
 *
 *   {
 *     // --------------------- Browser -----------------------
 *
 *     // Launch Chrome browser.
 *     await device.shell('am force-stop com.android.chrome');
 *     const context = await device.launchBrowser();
 *
 *     // Use BrowserContext as usual.
 *     const page = await context.newPage();
 *     await page.goto('https://webkit.org/');
 *     console.log(await page.evaluate(() => window.location.href));
 *     await page.screenshot({ path: 'page.png' });
 *
 *     await context.close();
 *   }
 *
 *   // Close the device.
 *   await device.close();
 * })();
 * ```
 *
 * Note that since you don't need Playwright to install web browsers when testing Android, you can omit browser download
 * via setting the following environment variable when installing Playwright:
 *
 * ```bash js
 * PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 npm i -D playwright
 * ```
