### 6.4.1. Introduction to architecture

This is a client-server application. We refer to the client part as the Integrated Test Environment or ITE, and the server component as the AUT Agent.:

The ITE

  is where tests are specified and evaluated.

The AUT Agent

  controls the application under test (AUT) and executes the specified tests.

You can install the ITE and AUT Agent on different machines; even on different platforms. This lets you specify and run your tests on different machines, and means that you can run the same test on different platforms.
