Question

我正在使用play和mockito对我的scala进行测试这是我的代码：

@RunWith(classOf[JUnitRunner])
class ProductServiceTests extends Specification
with ProductRepositoryComponent
with ProductServiceComponentImpl
with Mockito
 {

  val productRepository = mock[ProductRepository]
  val productId = "d3d08285-512f-46a6-811f-1abeb94ebb98"
  val product:Product = new Product(Option(productId), "default name", "default description", new References(Some("1"), Some("1"), Some("1"), Some("1")))
  val language = "en_US"
  val tenantId = ""

  def mockStuff = {
    productRepository.addProduct(any[String], any[String], any[Product]) returns
    product.id.get

    productRepository.updateProduct(any[String], any[String], any[Product]) returns
    product.id.get
  }

  step(mockStuff)

  "ProductService" should {
    "add minimal product to product repository" in {
      val result = productService.addProduct(language, tenantId, product)
      result mustNotEqual null
      result must beAnInstanceOf[DTOResponse[String]]
      val resultAsStr = result.asInstanceOf[DTOResponse[String]].get
      resultAsStr.length mustEqual 36 //Guid length
      resultAsStr mustEqual productId
    }

     //How can i override addProduct - So that from now on, it will use the exception throwing add Product.. (commented one)
    "update product in repository" in {
      val result = productService.addProduct("he_IL", tenantId, product)
      result mustNotEqual null
      result must beAnInstanceOf[DTOResponse[String]]
      val resultAsStr = result.asInstanceOf[DTOResponse[String]].get
      resultAsStr.length mustEqual 36 //Guid length
      resultAsStr mustEqual productId
    }
  }  
}

我在2里面有 ..如何覆盖第二个的addProduct方法？

我的问题是我要模拟2个addProduct函数，一个是好的，另一个将无效，因为Id已经存在..

谢谢！

也许这会对某人有所帮助..

在定义mockStuff时，One应该反复实现相同的方法，但每次参数都不同，然后在调用该方法时，将params点提供给您在函数中编写的实现。
应该记住的另一个问题是只应抛出 RuntimeException 。例如，在我的样本中，当我把He_IL放入时我希望抛出异常，所以我用字符串＆＃34; He_IL＆＃34;来调用我的函数。然后我会得到＆＃34; getProduct＆＃34;抛出异常：

with Mockito
 {
  val productRepository = mock[ProductRepository]
  val productId = "d3d08285-512f-46a6-811f-1abeb94ebb98"
  val product:Product = new Product(Option(productId), "default name", "default description", new References(Some("1"), Some("1"), Some("1"), Some("1")))
  val language = "en_US"
  val tenantId = ""

  def mockStuff = {
    productRepository.addProduct(any[AddProductRequest]) returns
    product.id.get

    productRepository.addProduct(AddProductRequest("He_IL",tenantId, product)) throws new RuntimeException("Language must be english !! !!")        
  }

step(mockStuff)

  "ProductService" should {
    "add product with only required fields to product repository" in {
      val result = productService.addProduct(AddProductRequest(language, tenantId, product))
      result mustNotEqual null
      result must beAnInstanceOf[DTOResponse[String]]
      val resultAsStr = result.asInstanceOf[DTOResponse[String]].get
     resultAsStr mustEqual productId
    }


    "add product when getting exception from product repository" in {
      val result = productService.addProduct(AddProductRequest("He_IL", tenantId, product))
      result mustNotEqual null
      result must beAnInstanceOf[DTOResponse[String]]
      val resultAsStr = result.asInstanceOf[DTOResponse[String]].get
     resultAsStr mustEqual productId
    }

在scala / mockito / play中的同一类中的测试之间替换mockito函数
