Issue with multiple identical setups

[koder-man]

Seen with 4.18.1.

Suppose we have this interface:

public interface ISample
{
    void Mock(object fi);
}

And the following code:

var mock = new Mock<ISample>();
mock.Setup(x => x.Execute(It.Is<object>(_ => true))).Verifiable();

var flag = true;
mock.Setup(x => x.Execute(It.Is<object>(_ => flag))).Verifiable();

mock.Object.Execute(new object());

mock.Verify();

Calling to mock.Verify():

• Expected behaviour: call succeeds (behaviour in 4.18.0 and before).
• Actual behaviour: call fails with error:

This mock failed verification due to the following:

MockSetupTests.ISample x => x.Execute(It.Is<object>(_ => True)):
This setup was not matched.

Except those setups aren't truly identical. The question here is when captured variables should be resolved to their values: at the time when the setup is created vs. when an invocation happens that could match the setup.

There have been a few recent changes to this, so not sure we can go back to the previous behavior in your precise use case... but I'll look into it.
