Stubbing out confirm dialogs in Jasmine

Ever write a javascript test suite only to have it interrupted by confirm dialogs in your code? Obnoxious huh?

Bypass them by stubbing out with the value you want the user to pick, true/false.

spyOn(window, ‘confirm’).andReturn(false);


spyOn(window, 'confirm').andReturn(true);

happy testing...

Just wanted to note that the syntax for this as of Jasmine 2.0 would be:

spyOn(window, 'confirm').and.returnValue(true)


spyOn(window, 'confirm').and.returnValue(false)
