Name an assertion/property

As far as I can see, when a test is run the failed message returns the actual and expected values, but there is no name of the property shown.

So if I say

5.Should().Be(10);

It returns “Message: Expected 10, but found 5”, but if you have multiple assertions you have no idea which one failed.

Could you not add a named property to Should or a fluent method like .Named(string name) and then add the name to the output messages. I think this would work well and could look like:

5.Should("some number").Be(10);

5.Should().Named("some number").Be(10) 

would give “some number: Expected 10, but found 5”

Although I recognize the possible usefulness of the idea, I think by now we have enough tools to help us identify the failed assertion.

• First of all, there is subject identification. As far as I understand it was not available three years ago.
• Secondly, there is the because parameter?
• Lastly, unit test runners automatically point you to the line that threw the exception.

@mika76 Would you agree that adding functionality you described would bring little gain in some very specific cases? In that case, you could close the issue.

@krajek it seems subject does exactly what I originally wanted. This is great! Will close.
