InvalidOperationException throw in HeaderMultiValueAssertion

[kvpt]

Hi,

Following the update to Alba 7.2.0 I have some tests that fail with an InvalidOperationException.

My test has this form

[Fact]
public async Task ShouldGetLastVersion()
{
    await Api.Scenario(s =>
    {
        s.Head
            .Url("version/last");

        s.StatusCodeShouldBe(HttpStatusCode.OK);

        s.Header(HeaderNames.ETag).ShouldHaveValues();
    });
}

The issue seems to be in the HeaderMultiValueAssertion, the excepted is empty and cause the aggregate to throw.

Hey, thanks for reporting this. ShouldHaveValues() was actually never intentionally designed to work with no values passed in, so the fact this worked to begin with was a happy accident. I've added a new overload for this scenario that uses a different assertion in v7.2.1.
