使用 StepVerifier 进行简单服务时，Groovy Spock 测试失败

Question

我正在尝试测试我的服务 ProductService，但它失败，表明断言是 MonoJust 而不是我期望的产品。我不知道为什么测试因该问题而失败。我希望能得到一些帮助来解决这个问题

下面是我的存储库、服务和测试代码

           class Product  {
                
                 String name
                 String productCode
                 int quantity
                 double price
            }


           interface ProductRepository extends ReactiveMongoRepository<Product, Long> {

           }

           class ProductService {
                 ProductRepository productRepository;
                 
                 ProductService(ProductRepository productRepository) {
                  this.productRepository = productRepository
                 }

                 Mono<Product> saveProduct(Mono<Product> product){
                 return  product.flatMap ( _prod -> productRepository.save(_prod))
              }
           }

            import reactor.core.publisher.Mono
            import reactor.test.StepVerifier
            import spock.lang.Specification
            
            import static org.assertj.core.api.Assertions.assertThat
            
            class ProductServiceSpec extends Specification{
                
                ProductRepository productRepository = Mock()
                ProductService productService = new ProductService(productRepository)
            
                def "should save a product to database"() {
                    given:
                    def product = new Product("T-Shirt", "LG-TSHRT", 1220, 7.77)
                    def productMono = Mono.just(product)
                    productMono.flatMap {productRepository.save(it) } >> productMono
            
                    when:
                    Mono<Product> productResult = productService.saveProduct(productMono)
            
                    then:
                    StepVerifier.create(productResult)
                            .expectNext(config)
                            .assertNext(_product -> {
                                assertThat(product.getName()).isEqualTo("T-Shirt")
                            })
                            .expectComplete()
                            .verify()
                }
            }

如果我是你，我会使用expectNextMateches。 类似这样的事情

                    StepVerifier.create(productResult)
                        .expectNextMatches(product -> product.getName().isEqualTo("T-Shirt"))
                        .expectComplete()
                        .verify()

请记住，您可以使用 && 或 || 添加多个匹配项运营商
