A Thick Client (also referred to as a fat client) is a purpose built piece of software that has been developed to work as a client with a server. It often has substantial business logic embedded within it, beyond the simple validation that is able to be achieved through a web browser. A thick client is often able to be very efficient with the amount of data that is transferred between it and its server, but is also often sensitive to any poor communications links. Testing tools such as WinRunner are able to be used to drive a Thick Client, so that response time can be measured under a variety of circumstances within a testing regime.
Developing a load test based on thick client activity usually requires significantly more effort for the coding stage of testing, as VUGen must be used to simulate the protocol between the client and the server. That protocol may be database connection based, COM/DCOM based, a proprietary communications protocol or even a combination of protocols.
