Importance of Resolution Testing

Few Days back we got a bug from our client when the application was in Production Server.They got java script error and blank page while accessing a particular menu. (Find the Screen shot below)

It was straightly forwarded to the development team by our project manager.
They tried many times to reproduce the issue but they can’t.At last as usual it came to our testing team and we also tried to reproduce the same and failed.

We tried in lot of scenarios and by changing the system environment also.
At Last we changed our screen resolution into 800 * 600 pixels and tried to access the same menu which was reported by our client and we got the same error this time.

At that day we learnt a lesson to test the application by changing the screen resolution.After that we had added this scenario into our lesson learnt document and also in Test Scenario document.

Many of us were aware of this type of Resolution Testing. But due to lack of schedule we missed to execute these scenarios and these things will become very big issues to the client.

So make sure to test the application by changing the screen resolution before delivering the application to the client.
