创建一个用Kotlin和Spek初始化共享对象的抽象Spek

Question

我试图用Kotlin + Spek框架编写单元测试。到目前为止，看起来还不错，但是我有一个问题，如果我想要为我测试的一个类有几个Spec对象，我必须编写大量的样板代码。

这是我用来说明问题的代码：

object MyFirstSpec : Spek({
    val myMock1: SomeObject1 = mock()
    val myMock2: SomeObject2 = mock()
    val myMock3: SomeObject3 = mock()
    val myMock4: SomeObject4 = mock()
    val myMock5: SomeObject5 = mock()
    val myMock6: SomeObject6 = mock()

    val myClass = MyClassToTest(myMock1, myMock2, myMock3, myMock4, myMock5, myMock6)

    given("something to test here") {
        //my test here
    }
})

object MyOtherSpec : Spek({
    val myMock1: SomeObject1 = mock()
    val myMock2: SomeObject2 = mock()
    val myMock3: SomeObject3 = mock()
    val myMock4: SomeObject4 = mock()
    val myMock5: SomeObject5 = mock()
    val myMock6: SomeObject6 = mock()

    val myClass = MyClassToTest(myMock1, myMock2, myMock3, myMock4, myMock5, myMock6)

    given("something else to test here") {
        //  my test here
    }
})

我想要创建‘抽象’Spek，在这里我将定义我的模拟等等，然后继承或共享它在我的规范中。

有办法做到这一点吗？

不幸的是，我没有找到做出抽象说明或继承的方法，但我找到了使用固定装置来实现预期结果的方法。

下面是我的伪代码，演示它：

object MySpec: Spek({
    describe("my tests with Fixtures") {
        val myMock1: SomeObject1 = mock()
        val myMock2: SomeObject2 = mock()
        val myMock3: SomeObject3 = mock()
        val myMock4: SomeObject4 = mock()
        val myMock5: SomeObject5 = mock()
        val myMock6: SomeObject6 = mock()

        val myClass = MyClassToTest(myMock1, myMock2, myMock3, myMock4, myMock5, myMock6)

        afterEachTest { 
            reset(myMock1, myMock2, myMock3, myMock4, myMock5, myMock6)
            //or we can just clear invocations, if we don't want to reset the mocks
            //clearInvocations(myMock1, myMock2, myMock3, myMock4, myMock5, myMock6)
        }

        context("my first context for testing") {
            //initialization logic here specific for this context
            val somethingSpecificHere = MySpecificLogicObject()
            beforeEachTest { 
                whenever(myMock1.doSomething()).thenReturn(someResult)
            }
            on ("calling the method i'm testing"){
                myClass.myMethod(somethingSpecificHere)

                it ("should do what expected") {
                    //verifies go here
                }
            }
        }
        context("my seconds context for testing") {
            //second context specific code
        }
    }
})

希望这对有同样问题的人有帮助。
