What are the different tests that can be done for Client Server Application and Web-based Application

For both client server and web based applications, the testing is the same except one thing: We test web based applications in different browsers, for example, Internet Explorer (will test in different versions like IE 5.0, IE 6.0, IE 7.0, IE8.0), Firefox, Safari (for Mac) and so on where as for client server, we don’t need to test in the browsers.
