How to find Unit Tests that call a specific method during their execution?

Consider I have a Method M() which will be called during execution of Tests T1() and T2().

Is there a way to find out that M will be executed in T1 and T2?

I know that it would be impossible to find it out through the code. But using history of Unit Test's executions is good too.

OpenCover (also available via nuget) has this as a feature -coverbytest, the results of which can be visualized using ReportGenerator.

NCrunch is a great testing tool (paid) which shows test coverage (including in those methods) inline and in reporting (metrics).

NSubstitute (and others) allow you to do checks such as .Recieved() that allow you to specific both arguments expected and how many times you expected it to be called (or not called!)

http://nsubstitute.github.io/help/received-calls/

[Test]
public void Should_execute_command_the_number_of_times_specified() {
  var command = Substitute.For<ICommand>();
  var repeater = new CommandRepeater(command, 3);
  //Act
  repeater.Execute();
  //Assert
  command.Received(3).Execute(); // << This will fail if 2 or 4 calls were received
}
