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 f

Answer 1

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());

Answer 2

To augment Ogata's answer, we can also verify a protected method that takes arguments:

testBaseMock.Protected().Setup(
    "ChildMethod1",
    ItExpr.IsAny<string>(),
    ItExpr.IsAny<string>());

testBaseMock.Protected().Verify(
    "ChildMethod1", 
    Times.Once(),
    ItExpr.IsAny<string>()
    ItExpr.IsAny<string>());

For instance, that would verify ChildMethod1(string x, string y).
