+ * Uses [TestCafe](https://github.com/DevExpress/testcafe) library to run cross-browser tests.
+ * The browser version you want to use in tests must be installed on your system.
+ *
+ * Requires `testcafe` package to be installed.
+ *
+ * ## Configuration
+ *
+ * This helper should be configured in codecept.json or codecept.conf.js
+ *
+ * * `url`: base url of website to be tested
+ * * `show`: (optional, default: false) - show browser window.
+ * * `windowSize`: (optional) - set browser window width and height
+ * * `getPageTimeout` (optional, default: '30000') config option to set maximum navigation time in milliseconds.
+ * * `waitForTimeout`: (optional) default wait* timeout in ms. Default: 5000.
+ * * `browser`: (optional, default: chrome)  - See https://devexpress.github.io/testcafe/documentation/using-testcafe/common-concepts/browsers/browser-support.html
+ *
+ *
+ * #### Example #1: Show chrome browser window
+ *
+ * ```json
+ * {
+ *    "helpers": {
+ *      "TestCafe" : {
+ *        "url": "http://localhost",
+ *        "waitForTimeout": 15000,
+ *        "show": true,
+ *        "browser": "chrome"
+ *      }
+ *    }
+ * }
+ * ```
+ *
+ *
+ * ## Access From Helpers
+ *
+ * Call Testcafe methods directly using the testcafe controller.
+ *
+ * ```js
+ * const testcafeTestController = this.helpers['TestCafe'].t;
+ * const comboBox = Selector('.combo-box');
+ * await testcafeTestController
+ *   .hover(comboBox) // hover over combo box
+ *   .click('#i-prefer-both') // click some other element
+ * ```
+ *
