Javascript Dialogs

Browser modal dialogs can be troublesome for automation testers. Since it is a modal, the browser does not proceed with automation unless someone acts upon these dialogs. Sahi is built for parallel playback where browsers need not be in focus. Sahi has specific mechanisms to deal with modal dialogs.

Sahi handles these dialogs by mocking them out. You will not see a dialog box when you playback via Sahi. However you will be able to control the user interaction with these dialogs with specific Sahi APIs.

Alert

An alert box looks like this: There are 3 APIs used with alerts.

Alert Example

_expectAlert("/abc/", false); // Tell Sahi to press OK for dialog with message containing "abc"
_click(_button("Click Me")); // trigger the alert
_assertEqual("abc", _lastAlert()); // verify the alert message

Confirm

A confirm dialog looks like this: In a confirm dialog the user can either press OK or Cancel. Sahi by default clicks OK on the dialog. Sahi can also be told to press Cancel.

Confirm Example

// To click Cancel, use
_expectConfirm("/question/", false); // Tell Sahi to press Cancel for dialog with message containing "question"
_click(_button("Click For Confirm")); // Invoke the dialog
// Sahi would click cancel on it now
_assertEqual("Some question?", _lastConfirm()); // verify the actual confirm message

Prompt

A prompt box looks like this: A prompt dialog is not very commonly used. Sahi by default behaves as if OK was pressed without entering any text. Sahi can be forced to enter text by setting an expectation via _expectPrompt API. The message on the prompt box can be obtained later by _lastPrompt() API.

Prompt Example

_expectPrompt("/Some prom/", "abc"); // set expectation
_click(_button("Click For Prompt")); // click for prompt
// abc would be entered by Sahi in the prompt box.
_assertEqual(_lastPrompt(), "Some prompt?"); // verify the full prompt dialog message

Print dialog

Calling the print dilaog during functional test automation is not of much use. However, we can verify if window.print() was called using the following APIs
