Verify the number of times a protected method is called using Moq

Question

In my unit-tests I'm mocking a protected method using Moq, and would like to assert that it is called a certain number of times. This question describes something similar for an earlier version of Moq:

//expect that ChildMethod1() will be called once. (it's protected)
testBaseMock.Protected().Expect("ChildMethod1")
  .AtMostOnce()
  .Verifiable();

...
testBase.Verify();

but this no longer works; the syntax has changed since then and I cannot find the new equivalent using Moq 4.x:

testBaseMock.Protected().Setup("ChildMethod1")
  // no AtMostOnce() or related method anymore
  .Verifiable();

...
testBase.Verify();

Answer 1

You can use the Times class:

logger.Verify(x => x.LogTrace(expectedMessage), Times.Once());

Answer 2

In the Moq.Protected namespace, there is an IProtectedMock interface that has a Verify method taking Times as a parameter.

Edit This is available since at least Moq 4.0.10827. Syntax example:

testBaseMock.Protected().Setup("ChildMethod1");

...
testBaseMock.Protected().Verify("ChildMethod1", Times.Once());
