HostLoom.Mapping.Testing

Builds a HostLoom.Mapping dispatcher from explicit maps, without a container.

IMapper mapper = new TestMapperBuilder()
    .Add<Customer, CustomerDto>(new CustomerMapper())
    .Add<Address, AddressDto>(source => new AddressDto(source.City, source.PostalCode))
    .Build();

var dto = mapper.From(customer).To<CustomerDto>();

The core package has no dependency-injection dependency, which is the right boundary but leaves a unit test that wants the dispatcher building an IServiceCollection to get one. This builds the same contract directly.

Substituting IMapper is the other option and a worse one. It needs a substitute per pair, and each returns what the test told it to rather than what the map would — so the test passes whether or not the map is correct. A real map, or an inline Func, keeps the assertion about behaviour.

Duplicate pairs are rejected here exactly as MappingBuilder rejects them, so a test cannot pass against a composition the container would refuse. A missing pair throws MappingNotFoundException naming both types and the destinations the source is mapped to.

Consumers that take a closed IMapper<TSource, TDestination> — the shape the HostLoom.Mapping README recommends — need nothing from this package: construct the map class and pass it.
