Unit Testing: Logging and Dependency Injection

Question

So regards logging from SO and other sites on the Internet the best response seems to be:

void DoSomething() {
    Logger.Log(\"Doing something!\");
    // Code.         


        

Answer 1

I'd say it's probably a reasonable thing to write a Unit Test for logging; I've done so before, and it turned out to be more useful than I initially anticipated. Generally, Unit Testing logging gives you good assurance that the logging facility is working at Unit Test time, which can be a nice assurance. I don't find it critical to Unit Test logging, but if you have the inclination, I doubt that it'll be a bad thing, either.
