alert() dialogs have a single ok button, and no choice is given. Right after the action (clicking on a link or a button ) that triggers the alert, you need to acknowledge and close it. You can do this with the command:
copado=button:Show an alert
The parameter "*" means "any text", and will match any text shown in the dialog.
confirm() dialogs have two buttons, typically ok and cancel.
If you need to make a choice between the two actions, you need to add one of the following commands before the action that will open a dialog, and acknowledge the confirm() dialog afterwards:
copado=button:Show a confirm
The choice is optional. You can omit chooseOkOnNextConfirmation / chooseCancelOnNextConfirmation and by default the dialog will be closed by clicking on OK.
prompt() dialogs have two buttons, typically ok and cancel, and the user can enter some text in it.
In order to enter the text, you need to add answerOnNextPrompt before the action that will open it.
copado=button:Enter a number
