/**

|
|
* :::warning
|
||
|
|
* The `executeAsync` command is deprecated and will be removed in a future version.
|
||
|
|
* Please use the `execute` command instead as it provides better support for
|
||
|
|
* error handling via `async`/`await`.
|
||
|
|
* :::
|
||
|
|
*
|
||
|
|
* Inject a snippet of JavaScript into the page for execution in the context of the currently selected
|
||
|
|
* frame using the given element as scope, because it is on the element scope it means that WebdriverIO will
|
||
|
|
* automatically wait for the element to exist before executing the script.
|
||
|
|
* The executed script is assumed to be asynchronous and must signal that is done by invoking
|
||
|
|
* the provided callback, which is always provided as the final argument to the function. The value
|
||
|
|
* to this callback will be returned to the client.
|
||
|
|
*
|
||
|
|
* Asynchronous script commands may not span page loads. If an unload event is fired while waiting
|
||
|
|
* for a script result, an error should be returned to the client.
|
||
|
|
*
|
||
|
|
* The script argument defines the script to execute in the form of a function body. The function will
|
||
|
|
* be invoked with the provided args array and the values may be accessed via the arguments object
|
||
|
|
* in the order specified. The final argument will always be a callback function that must be invoked
|
||
|
|
* to signal that the script has finished.
|
||
|
|
*
|
||
|
|
* Arguments may be any JSON-primitive, array, or JSON object. JSON objects that define a WebElement
|
||
|
|
* reference will be converted to the corresponding DOM element. Likewise, any WebElements in the script
|
||
|
|
* result will be returned to the client as WebElement JSON objects.
