c# - Is it important to unit test a constructor?

Question

Ought I to unit test constructors? Say I have a constructor like this:

IMapinfoWrapper wrapper;
public SystemInfo(IMapinfoWrapper mapinfoWrapper)
{
    this.wrapper = mapinfoWrapper;
}

Do I need to write a unit test for this construtor? I don't have any getters for the wrapper variable, so I don't need to test that.

Unit testing is about testing the public states, behaviors, and interactions of your objects.

If you simply set a private field in your constructor, what is there to test?

Don't bother unit-testing your simple accessors and mutators. That's just silly, and it doesn't help anyone.
