The Failure Emulator profiler tracks whether the code of the profiled application contains lines that prevent the application from unexpected failures. This profiler is very useful if you need to verify that your application behaves correctly in unexpected situations. For example, using this profiler you can check whether the application that modifies the .txt file fails when it tries to access the file when access to the file is denied.
AQTime offers you various types of failures that can be emulated using AQTime. For example, you can emulate the situation when a COM server is absent and then try to connect to this server from your application. The main advantage of this profiler is that you do not need to do anything with the server. AQTime will just make your application "think" that the server is absent.
This tutorial demonstrates how you can use the Failure Emulator profiler to analyze your applications.
