Verifying private method call (VB)

0 votes
From the Isolator documentation, I saw how to check if a private method was called using c#: 
[TestMethod]
[Isolated]
public void StubPrivateMethod()
{
    RealLogger fake = Isolate.Fake.Instance<RealLogger>();

    // Avoid performing actual write to disk by ignoring (stubbing) a private call
    Isolate.NonPublic.WhenCalled(fake, "WriteToDisk").IgnoreCall();

    // This call is faked - count should not increment
    fake.Log("Hello World");

    Assert.AreEqual(1, fake.LineCount);
    // Verify the private call was actually made
    Isolate.Verify.NonPublic.WasCalled(fake, "WriteToDisk").WithArguments("Hello World");
}

How do I do this using VB syntax? I didn't see anything like that in the VB docs.

Hi,

You should use NonPublicWillBeIgnored() and its sister methods (NonPublicWillReturn, NonPublicWillCallOriginal, NonPublicWillThrow etc.).

I will make sure we update our docs for a future version.

Thanks,

Using these 3 methods change the behavior of the call. How would I verify that a private method is called?

So the VB equivalent of this: 
// Verify the private call was actually made
    Isolate.Verify.NonPublic.WasCalled(fake, "WriteToDisk").WithArguments("Hello World");

I don't see a method that would be able to be used in the VB: 
Using AssertCalls.HappenedWithExactArguments
    fake.WriteToDisk("Hello World") 'compiler error
End Using

On the other hand, how do you verify a private method was NOT called 
Using AssertCalls.NeverHappened
    fake.WriteToDisk("Hello World") 'compiler error
End Using
