/**
 * - 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);
 * ```
 *

   * Routing provides the capability to modify network requests that are made by a page.

   *
   * > NOTE: The handler will only be called for the first url if the response is a redirect.
   * > NOTE: [page.route(url, handler[, options])](https://playwright.dev/docs/api/class-page#page-route) will not intercept
   * requests intercepted by Service Worker. See [this](https://github.com/microsoft/playwright/issues/1090) issue. We
   * recommend disabling Service Workers when using request interception. Via `await context.addInitScript(() => delete
   * window.navigator.serviceWorker);`
   *
   * An example of a naive handler that aborts all image requests:
   *
   * ```js
   * const page = await browser.newPage();
   * await page.route('**\/*.{png,jpg,jpeg}', route => route.abort());
   * await page.goto('https://example.com');
   * await browser.close();
   * ```
   *
   * or the same snippet using a regex pattern instead:
   *
   * ```js
   * const page = await browser.newPage();
   * await page.route(/(\.png$)|(\.jpg$)/, route => route.abort());
   * 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 => {
   *   if (route.request().postData().includes('my-string'))
   *     route.fulfill({ body: 'mocked-data' });
   *   else
   *     route.continue();
   * });
   * ```
   *
   * Page routes take precedence over browser context routes (set up with
   * [browserContext.route(url, handler[, options])](https://playwright.dev/docs/api/class-browsercontext#browser-context-route))
   * when request matches both handlers.
   *
   * To remove a route with its handler you can use

   * Routing provides the capability to modify network requests that are made by any page in the browser context. Once route
   * is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.
   *
   * > NOTE: [page.route(url, handler[, options])](https://playwright.dev/docs/api/class-page#page-route) will not intercept
   * requests intercepted by Service Worker. See [this](https://github.com/microsoft/playwright/issues/1090) issue. We
   * recommend disabling Service Workers when using request interception. Via `await context.addInitScript(() => delete
   * 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();
   * ```
   *
   * or the same snippet using a regex pattern instead:
   *
   * ```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' });
   *   else
   *     route.continue();
   * });
   * ```
   *
   * Page routes (set up with [page.route(url, handler[, options])](https://playwright.dev/docs/api/class-page#page-route))
   * take precedence over browser context routes when request matches both handlers.
   *
   * To remove a route with its handler you can use

 * ElementHandle represents an in-page DOM element. ElementHandles can be created with the
 * [page.$(selector[, options])](https://playwright.dev/docs/api/class-page#page-query-selector) method.
 *
 * > NOTE: The use of ElementHandle is discouraged, use [Locator] objects and web-first assertions instead.
 *
 * ```js
 * const hrefElement = await page.$('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.$eval(selector, pageFunction[, arg, options])](https://playwright.dev/docs/api/class-page#page-eval-on-selector)
 * and [page.evaluate(pageFunction[, arg])](https://playwright.dev/docs/api/class-page#page-evaluate) methods.
 *
 * The difference between the [Locator] and ElementHandle is that the ElementHandle points to a particular element, while
 * [Locator] captures the logic of how to retrieve an element.
 *
 * In the example below, handle points to a particular DOM element on page. If that element changes text or is used by
 * React to render an entirely different component, handle is still pointing to that very DOM element. This can lead to
 * unexpected behaviors.
 *
 * ```js
 * const handle = await page.$('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();
 * ```

/**
 * 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
 * ```

/**
 * Test runner notifies the reporter about various events during test execution. All methods of the reporter are optional.

 * You can create a custom reporter by implementing a class with some of the reporter methods. Make sure to export this

 * ```ts
 * // my-awesome-reporter.ts
 * import { Reporter } from '@playwright/test/reporter';
 *
 * class MyReporter implements Reporter {
 *   onBegin(config, suite) {
 *     console.log(`Starting the run with ${suite.allTests().length} tests`);
 *   }
 *
 *   onTestBegin(test) {
 *     console.log(`Starting test ${test.title}`);
 *   }
 *
 *   onTestEnd(test, result) {
 *     console.log(`Finished test ${test.title}: ${result.status}`);
 *   }
 *
 *   onEnd(result) {
 *     console.log(`Finished the run: ${result.status}`);
 *   }
 * }
 * export default MyReporter;
 * ```
 *
 * Now use this reporter with [testConfig.reporter](https://playwright.dev/docs/api/class-testconfig#test-config-reporter).
 * Learn more about [using reporters](https://playwright.dev/docs/test-reporters).
 *
 * ```ts
 * // playwright.config.ts
 * import { PlaywrightTestConfig } from '@playwright/test';
 *
 * const config: PlaywrightTestConfig = {
 *   reporter: './my-awesome-reporter.ts',
 * };
 * export default config;
 * ```
 *
 * Here is a typical order of reporter calls:
 * - [reporter.onBegin(config, suite)](https://playwright.dev/docs/api/class-reporter#reporter-on-begin) is called once
 *   with a root suite that contains all other suites and tests. Learn more about [suites hierarchy][Suite].
 * - [reporter.onTestBegin(test, result)](https://playwright.dev/docs/api/class-reporter#reporter-on-test-begin) is
 *   called for each test run. It is given a [TestCase] that is executed, and a [TestResult] that is almost empty. Test
 *   result will be populated while the test runs (for example, with steps and stdio) and will get final `status` once
 *   the test finishes.
 * - [reporter.onStepBegin(test, result, step)](https://playwright.dev/docs/api/class-reporter#reporter-on-step-begin)
 *   and [reporter.onStepEnd(test, result, step)](https://playwright.dev/docs/api/class-reporter#reporter-on-step-end)
 *   are called for each executed step inside the test. When steps are executed, test run has not finished yet.
 * - [reporter.onTestEnd(test, result)](https://playwright.dev/docs/api/class-reporter#reporter-on-test-end) is called
 *   when test run has finished. By this time, [TestResult] is complete and you can use
 *   [testResult.status](https://playwright.dev/docs/api/class-testresult#test-result-status),
 *   [testResult.error](https://playwright.dev/docs/api/class-testresult#test-result-error) and more.
 * - [reporter.onEnd(result)](https://playwright.dev/docs/api/class-reporter#reporter-on-end) is called once after all
 *   tests that should run had finished.
 *
 * Additionally,
 * [reporter.onStdOut(chunk, test, result)](https://playwright.dev/docs/api/class-reporter#reporter-on-std-out) and
 * [reporter.onStdErr(chunk, test, result)](https://playwright.dev/docs/api/class-reporter#reporter-on-std-err) are called
 * when standard output is produced in the worker process, possibly during a test execution, and
 * [reporter.onError(error)](https://playwright.dev/docs/api/class-reporter#reporter-on-error) is called when something
 * went wrong outside of the test execution.
