Revision to an XUnit test for identifying bad mappings. Unlike the standard test (which would fail after the first bad/missing mapping), this will print out all the unmapped property names in the solution in context with the mapping they belong to.

AutoMapperTest.cs

[Fact]
public void AssertConfigurationIsValid()
{
    try
    {
        Mapper.AssertConfigurationIsValid();
    }
    catch (AutoMapperConfigurationException amce)
    {
        foreach (var e in amce.Errors)
        {
            Console.WriteLine("Source Type Name: {0}", e.TypeMap.SourceType.Name);
            Console.WriteLine("Destination Type Name: {0}", e.TypeMap.DestinationType.Name);
            Console.WriteLine("Unmapped Properties:");
            foreach (var name in e.UnmappedPropertyNames)
            {
                Console.WriteLine(name);
            }
            Console.WriteLine();
        }
        throw;
    }
}
