open method
Call this method to start a test, before calling any of the check methods.
Syntax
let result = await eyes.open(driver, appName, testName, viewportSize);
Parameters
- appName
- Type:string
- The application name. This may be any string.
- testName
- Type:string
- The name of the test. This name must be unique within the scope of the application name. It may be any string.
- viewportSize
- Type:
{ width: number; height: number } The size of the viewport
The size of the viewport passed as an object.
The size of the viewport passed as an object {'width':, 'height':}
Defines the viewport size of the browser that will be set before the start of the test. If this parameter is not provided then the viewport size will be based on the current browser window size. See Using viewports in Eyes for more details.
- driver
- Type:WebDriver
- The web driver.
Return value
- Type: Promise<WebDriver>
- The returned web driver is a clone of the driver passed as a parameter. It is recomended that you use the web driver object returned by this method in all further calls to the web driver. This allows Eyes to record these interactions and play them back in the Eyes Test Manager.
Remarks
After making a call to this method, you must eventually terminate the test by calling
Eyes.close
(in case of a normal completion) or
Eyes.abortIfNotClosed
(in case of an aborted test).
If you want to run another test, then it is recomended to do this with a newly
created Eyes instance to avoid side effects. However, in principle, it is legal to call
Eyes.open again to start a new test
on the same Eyes instance.
