I have a system to test which maps data from one type to another type, lets call them Order and OrderDto

In my scenario, Order has many more properties than OrderDto so I use orderDto.Should().BeEquivalentTo(order, options => options.ExcludingMissingMembers()); to prevent an exception being thrown due to properties existing on Order which do not exist on OrderDto.

Some of the property names are slightly different between Order and OrderDto so I use options.WithMapping<OrderDto>(e => e.Name, s => s.OrderName) for each property that varies.

The problem is that I would like to ensure that every property that exists on OrderDto has been populated as it would be very easy to forget to add a WithMapping for a particular property, especially as things change in the future.

Is there a way to do this with object graph comparison like options.IncludingMembers<OrderDto>() or even an orderDto.Should().NotHaveNullProperties()?
