BrowserProvider Interface
To create a browser provider, implement the following methods.
While implementing the methods, you can utilize the testcafe-browser-tools library that contains methods for performing platform-dependent actions on browser windows. To do this, add this library as a dependency into your browser provider project.
Required Methods #
openBrowser #
Runs the specified browser and opens the specified page in it.
async openBrowser ( id, pageUrl, browserName )
Parameter | Type | Description |
---|---|---|
id |
String | A unique identifier generated by TestCafe that you can use to identify a browser window. The identifier is included to the window title exposed using the document.title property. |
pageUrl |

browserName |
String | The browser name. |
See Example.
closeBrowser #
Closes the specified browser.
async closeBrowser ( id )
Parameter | Type | Description |
---|---|---|
id |
String | A unique identifier generated by TestCafe that you can use to identify a browser window. |

Optional Methods #
init #
Performs initialization actions the provider may require. This method is called once before other provider methods are called.
async init ()
For example, the Nightmare browser provider uses this method to create a Nightmare instance.
dispose #
Performs cleanup actions for the provider data. This method is called before the testcafe
process is finished.
async dispose ()
getBrowserList #
