計算Spock中調用靜態方法的次數

Question

我正在計算調用靜態方法的次數。

我想驗證基本和內部方法調用的計數。

下面顯示的是一個非常簡化的代碼。我嘗試了一些變化，但不能沒有錯誤地運行。

我嘗試驗證的次數：

• ClassX.CallsClassY()
• ClassY.DoSomething()

請幫助。

錯誤消息：

Too few invocations for: 

interactions * globalMock.DoSomething() // Does not work (0 invocations) 

Unmatched invocations (ordered by similarity): 

2 * globalMock.DoSomething() 
2 * globalMock.println('Hello Spock') 

    at org.spockframework.mock.runtime.InteractionScope.verifyInteractions(InteractionScope.java:78) 
    at org.spockframework.mock.runtime.MockController.leaveScope(MockController.java:76) 
    at SpockSpec.Count how many times ClassY is called(SpockSpec.groovy:10) 

代碼：

import spock.lang.Specification 

    class SpockSpec extends Specification { 
     def "Count how many times ClassY is called"(){ 
     def count = 5 
     def interactions = count + 1 
     def globalMock = GroovySpy(ClassY, global: true) 

     when: 
     ClassX.CallClassY(count) 

     then: 
     count == 5 
     // TODO: Count how many times ClassY.DoSomething() and ClassX.CallClassY() is called 
     interactions * globalMock.DoSomething() // Does not work 
    } 

    class ClassX { 

     public static void CallClassY(int count) 
     { 
      count.times { 
       ClassY.DoSomething() 
      } 

      ClassY.DoSomething() 
     } 
    } 

    class ClassY { 
     static void DoSomething() { 
      println "Hello Spock" 
     } 
    } 
}

你可以做類似

def "Count how many times ClassB is called"(){ 
     given: 
      def calls = 0 
     and: 
      ClassY.metaClass.'static'.DoSomething = { 
       calls++ 
      } 
     and: 
      def count = 5   
     when: 
      ClassX.CallClassY(count) 
     then: 
      count == calls + 1 
    }
