Truques para testes unitários

Some random notes about unit tests, mostly with Asp.net Boilerplate:

var objectMapper = new Abp.AutoMapper.AutoMapperObjectMapper(
                new Mapper(
                    new MapperConfiguration(cfg =>
                    {
                        cfg.CreateMap<Entity, Dto>();
                        cfg.CreateMap<AnotherDto, AnotherEntity>()
                            .ForMember(e => e.SomeProperty, opt => opt.Ignore())
                            .ReverseMap()
                            .ForMember(dto => dto.SomeProperty, opt => opt.Ignore());                    })
                )
            );

component.l = (key: string, ...args: any): string => {
            return key;
        };
