This short post is about simple but effective test strategy that varies application environment: screen resolution.
When you test application, ask developers which resolution they use and then set the resolution for your computer screen to value that is less than minimal developers value. Screen resolutions have some standard values.
For example, if minimal developer resolution is 1440×900, you should set 1280×800.
Developers use large screens with big resolutions, so they are not best representatives for users of your application.
Using this strategy you will find corner view cases. If application view contains a lot of UI elements, then you issue will be dismissed. In that case, when you are testing again that application page, set you screen to larger resolution. But do not forget to set it back to lower one when you are done with that screen.by
