We support IE9, IE10, IE11, Chrome and Firefox, and we support them on Win7, Win8, Win8, and Win10.
If we tested every possible combination of browser and OS that would be 20 times through our script and we're wondering if that is necessary.
I'm fairly confident that the results we get for Chrome or Firefox on one OS will hold for all OS's, but we're not sure if there might be difference in the way certain versions of IE behave on the different OS's.
- Am I correct in assuming that Chrome and Firefox will be consistent across OS's?
- Will each version of IE be consistent across OS's or do we need to test each possible OS/Browser combo?
