A verify method that returns a boolean.

[NinoFloris]

Xunit 2 does not know the concept of NotThrows. I'd like to Assert something in my tests.
Verify() returns void or an exception. So in the case that I'd like to Assert something indeed was called according to Setup() I cannot Assert this because Verify() does not return a result.

Now I can do :

mock.Verify();
Assert.True(true);

But that's a bit ugly don't you think?

This is more of an issue with xUnit than with Moq. You could do the following, if you really wanted to:

var ex = Record.Exception(() => mock.Verify());
Assert.Null(ex);

Does that solve your issue?

I know but still, very ugly. I'd like an IsVerified bool property or something but I'll live without it ;)

How about creating your own extension method? Something along the lines of:

using System;
using System.Linq.Expressions;
using Moq;

static class MockExtensions
{
    public static bool TryVerify<T>(
        this Mock<T> mock,
        Expression<Action<T>> expression,  // delegate type according to Verify overload you want
        …,  // additional parameters according to Verify overload you want
        out Exception error)  // you might not be interested in this bit
    {
        try
        {
            mock.Verify(expression, …);
            error = null;
            return true;
        }
        catch (Exception ex)
        {
            error = ex; 
            return false;
        }
    }
}

Which you'd then use as follows:

var mock = new Mock<Foo>();
…
bool isVerified = mock.TryVerify(foo => …, …, out Exception error);
Assert.True(isVerified);

Well, I think that the Action<T> isn't even necessary :)

Alright thanks, commenting on your example I'd use tuples but ok, no bool method coming up. Closing this
