Question

I have some context in code to be switched depending on whether it is running under test or release.
Say in my product coding:

PublishRequest(); // the real one
//PublishRequestPsudo(); // the one want to be run during unit test

The way I am thinking about is make a TestFlag class:

if (!TestFlag.PublishFlag)
{
    PublishRequest();
}
else
{
    PublishRequestPsudo();
}

This seems verbose if I have many place to do that. Is there any good pattern to do it?

A pretty good way to acheive the same is Dependency Injection/Inversion Of Control
