1.	In N Tier Architecture What Factors Should Be Considered For Testing?
Answer» Basically 3-tier ARCHITECTURE is for windows based application. Whereas N-tier architecture is for web-based applications. So, We should do the testing related to web-testing. In 3 tier architecture there are 3 layers in the architecture. They are 1) Application(PRESENTATION) layer 2)Business Logic Layer and 3)Data layer. In n tier architecture, Data layer is divided into 2 layers i.e Data access and Database. In n tier architecture, Data access layer and Database layer MAY or may not reside on the same location. Keeping that into consideration we have to prepare Test strategy and Test Approach.
