 Usually you should place the executable under _/Applications_ so that the same instance can be shared across multiple projects, however there are scenarios where you might prefer to place the server's executable under your project _Pods_ folder. This can be achieved adding the following post_install step in your Podfile:

 Create an instance of `SBTUITunneledHostMouseClick` by passing the `XCUIElement` you want to be clicked (center of element will be clicked) and specifying a delay, in seconds, to wait after the click has been performed. This is useful if you need to create a sequence of `[SBTUITunneledHostMouseClick]`.
