/**
* ## Configuration
*
* This helper should be configured in codecept.conf.(js|ts)
*
* @typedef PlaywrightConfig
* @type {object}
* @prop {string} [url] - base url of website to be tested
* @prop {'chromium' | 'firefox'| 'webkit' | 'electron'} [browser='chromium'] - a browser to test on, either: `chromium`, `firefox`, `webkit`, `electron`. Default: chromium.
* @prop {boolean} [show=true] - show browser window.
* @prop {string|boolean} [restart=false] - restart strategy between tests. Possible values:
* * 'context' or **false** - restarts [browser context](https://playwright.dev/docs/api/class-browsercontext) but keeps running browser. Recommended by Playwright team to keep tests isolated.
* * 'browser' or **true** - closes browser and opens it again between tests.
* * 'session' or 'keep' - keeps browser context and session, but cleans up cookies and localStorage between tests. The fastest option when running tests in windowed mode. Works with `keepCookies` and `keepBrowserState` options. This behavior was default before CodeceptJS 3.1
* @prop {number} [timeout=1000] - - [timeout](https://playwright.dev/docs/api/class-page#page-set-default-timeout) in ms of all Playwright actions .
* @prop {boolean} [disableScreenshots=false] - don't save screenshot on failure.
* @prop {any} [emulate] - browser in device emulation mode.
* @prop {boolean} [video=false] - enables video recording for failed tests; videos are saved into `output/videos` folder
* @prop {boolean} [keepVideoForPassedTests=false] - save videos for passed tests; videos are saved into `output/videos` folder
* @prop {boolean} [trace=false] - record [tracing information](https://playwright.dev/docs/trace-viewer) with screenshots and snapshots.
* @prop {boolean} [keepTraceForPassedTests=false] - save trace for passed tests.
* @prop {boolean} [fullPageScreenshots=false] - make full page screenshots on failure.
* @prop {boolean} [uniqueScreenshotNames=false] - option to prevent screenshot override if you have scenarios with the same name in different suites.
* @prop {boolean} [keepBrowserState=false] - keep browser state between tests when `restart` is set to 'session'.
* @prop {boolean} [keepCookies=false] - keep cookies between tests when `restart` is set to 'session'.
* @prop {number} [waitForAction] - how long to wait after click, doubleClick or PressKey actions in ms. Default: 100.
* @prop {'load' | 'domcontentloaded' | 'commit'} [waitForNavigation] - When to consider navigation succeeded. Possible options: `load`, `domcontentloaded`, `commit`. Choose one of those options is possible. See [Playwright API](https://playwright.dev/docs/api/class-page#page-wait-for-url).
* @prop {number} [pressKeyDelay=10] - Delay between key presses in ms. Used when calling Playwrights page.type(...) in fillField/appendField
* @prop {number} [getPageTimeout] - config option to set maximum navigation time in milliseconds.
* @prop {number} [waitForTimeout] - default wait* timeout in ms. Default: 1000.
* @prop {object} [basicAuth] - the basic authentication to pass to base url. Example: {username: 'username', password: 'password'}

* @prop {object} [chromium] - pass additional chromium options
* @prop {object} [firefox] - pass additional firefox options
* @prop {object} [electron] - (pass additional electron options
* @prop {any} [channel] - (While Playwright can operate against the stock Google Chrome and Microsoft Edge browsers available on the machine. In particular, current Playwright version will support Stable and Beta channels of these browsers. See [Google Chrome & Microsoft Edge](https://playwright.dev/docs/browsers/#google-chrome--microsoft-edge).
* @prop {string[]} [ignoreLog] - An array with console message types that are not logged to debug log. Default value is `['warning', 'log']`. E.g. you can set `[]` to log all messages. See all possible [values](https://playwright.dev/docs/api/class-consolemessage#console-message-type).
* @prop {boolean} [ignoreHTTPSErrors] - Allows access to untrustworthy pages, e.g. to a page with an expired certificate. Default value is `false`
* @prop {boolean} [bypassCSP] - bypass Content Security Policy or CSP
* @prop {boolean} [highlightElement] - highlight the interacting elements. Default: false. Note: only activate under verbose mode (--verbose).
* @prop {object} [recordHar] - record HAR and will be saved to `output/har`. See more of [HAR options](https://playwright.dev/docs/api/class-browser#browser-new-context-option-record-har).

/**
* Uses [Playwright](https://github.com/microsoft/playwright) library to run tests inside:
*
* * Chromium
* * Firefox
* * Webkit (Safari)
*
* This helper works with a browser out of the box with no additional tools required to install.
*
* Requires `playwright` or `playwright-core` package version ^1 to be installed:
*
* ```
* npm i playwright@^1.18 --save
* ```
* or
* ```
* npm i playwright-core@^1.18 --save
* ```
*
* Breaking Changes: if you use Playwright v1.38 and later, it will no longer download browsers automatically.
*
* Run `npx playwright install` to download browsers after `npm install`.
*
* Using playwright-core package, will prevent the download of browser binaries and allow connecting to an existing browser installation or for connecting to a remote one.
*
*
* <!-- configuration -->
*
* #### Video Recording Customization
*
* By default, video is saved to `output/video` dir. You can customize this path by passing `dir` option to `recordVideo` option.
*
* `video`: enables video recording for failed tests; videos are saved into `output/videos` folder
* * `keepVideoForPassedTests`: - save videos for passed tests
* * `recordVideo`: [additional options for videos customization](https://playwright.dev/docs/next/api/class-browser#browser-new-context)
*
* #### Trace Recording Customization
*
* Trace recording provides complete information on test execution and includes DOM snapshots, screenshots, and network requests logged during run.
* Traces will be saved to `output/trace`
*
* * `trace`: enables trace recording for failed tests; trace are saved into `output/trace` folder
* * `keepTraceForPassedTests`: - save trace for passed tests
*
* #### HAR Recording Customization
*
* A HAR file is an HTTP Archive file that contains a record of all the network requests that are made when a page is loaded.
* It contains information about the request and response headers, cookies, content, timings, and more. You can use HAR files to mock network requests in your tests.
* HAR will be saved to `output/har`. More info could be found here https://playwright.dev/docs/api/class-browser#browser-new-context-option-record-har.
*
* ```
* ...
* recordHar: {
* mode: 'minimal', // possible values: 'minimal'|'full'.
* content: 'embed' // possible values: "omit"|"embed"|"attach".
* }
* ...
*```
*
* #### Example #1: Wait for 0 network connections.
*
* ```js
* {
* helpers: {
* Playwright : {
* url: "http://localhost",
* restart: false,
* waitForNavigation: "networkidle0",
* waitForAction: 500
* }
* }
* }
* ```
*
* #### Example #2: Wait for DOMContentLoaded event
*
* ```js
* {
* helpers: {
* Playwright : {
* url: "http://localhost",
* restart: false,
* waitForNavigation: "domcontentloaded",
* waitForAction: 500
* }
* }
* }
* ```
*
* #### Example #3: Debug in window mode
*
* ```js
* {
* helpers: {
* Playwright : {
* url: "http://localhost",
* show: true
* }
* }
* }
* ```
*
* #### Example #4: Connect to remote browser by specifying [websocket endpoint](https://playwright.dev/docs/api/class-browsertype#browsertypeconnectparams)
*
* ```js
* {
* helpers: {
* Playwright: {
* url: "http://localhost",
* chromium: {
* browserWSEndpoint: 'ws://localhost:9222/devtools/browser/c5aa6160-b5bc-4d53-bb49-6ecb36cd2e0a',
* cdpConnection: false // default is false
* }
* }
* }
* }
* ```
*
* #### Example #5: Testing with Chromium extensions
*
* [official docs](https://github.com/microsoft/playwright/blob/v0.11.0/docs/api.md#working-with-chrome-extensions)
*
* ```js
* {
* helpers: {
* Playwright: {
* url: "http://localhost",
* show: true // headless mode not supported for extensions
* chromium: {
* // Note: due to this would launch persistent context, so to avoid the error when running tests with run-workers a timestamp would be appended to the defined folder name. For instance: playwright-tmp_1692715649511
* userDataDir: '/tmp/playwright-tmp', // necessary to launch the browser in normal mode instead of incognito,
* args: [
* `--disable-extensions-except=${pathToExtension}`,
* `--load-extension=${pathToExtension}`
* ]
* }
* }
* }
* }
* ```
*
* #### Example #6: Launch tests emulating iPhone 6
*
*
*
* ```js
* const { devices } = require('playwright');
*
* {
* helpers: {
* Playwright: {
* url: "http://localhost",
* emulate: devices['iPhone 6'],
* }
* }
* }
* ```
*
* #### Example #7: Launch test with a specific user locale
*
* ```js
* {
* helpers: {
* Playwright : {
* url: "http://localhost",
* locale: "fr-FR",
* }
* }
* }
* ```
*
* * #### Example #8: Launch test with a specific color scheme
*
* ```js
* {
* helpers: {
* Playwright : {
* url: "http://localhost",
* colorScheme: "dark",
* }
* }
* }
* ```
*
* * #### Example #9: Launch electron test
*
* ```js
* {
* helpers: {
* Playwright: {
* browser: 'electron',
* electron: {
* executablePath: require("electron"),
* args: [path.join('../', "main.js")],
* },
* }
* },
* }
* ```
*
* Note: When connecting to remote browser `show` and specific `chrome` options (e.g. `headless` or `devtools`) are ignored.
*
* ## Access From Helpers
*
* Receive Playwright client from a custom helper by accessing `browser` for the Browser object or `page` for the current Page object:
*
* ```js
* const { browser } = this.helpers.Playwright;
* await browser.pages(); // List of pages in the browser
*
* // get current page
* const { page } = this.helpers.Playwright;
* await page.url(); // Get the url of the current page
*
* const { browserContext } = this.helpers.Playwright;
* await browserContext.cookies(); // get current browser context
* ```
