where-clause - 如何在 spock 测试的 where 子句中调用方法或闭包

Question

我正在使用 Spock 测试 atm，我想知道这样的事情是否可行。我的方法不起作用，我想知道你们中是否有人有类似的意图并找到了方法。

我想调用一个方法或一个闭包，必须只为每个各自的 where 子句调用它，以便设置一些东西。我不能只调用所有这些方法，因为它会破坏我的测试。到目前为止，我发现的唯一方法是检查当前状态并在 if 语句中相应地调用该方法，例如: if(state==SomeStateEnum.FIRST_STATE){somePrivateMethodFromSpec()} 但我想知道它是否无法完成以更好的方式。我希望我的意图很明确(对不起，我不是母语人士)下面是一些示例代码，可能会更好地理解我想要做什么。先感谢您。

def 'is this even possible?'() {
    when:
    def resultState = service.someServiceMethod(param)

    then:
    resultState == state

    where:
    state                       | param     | method
    SomeStateEnum.FIRST_STATE   | 'param1'  | somePrivateMethodFromSpec()
    SomeStateEnum.SECOND_STATE  | 'param2'  | someOtherPrivateMethodFromSpec()
}

private def somePrivateMethodFromSpec() {
    someServiceMock.demand.AAA() {}
}

private def someOtherPrivateMethodFromSpec() {
    someServiceMock.demand.BBB() {}
}

def 'or maybe something like this?'() {
    when:
    closure.call()
    def resultState = service.someServiceMethod(param)

    then:
    resultState == state

    where:
    state                       | param     | closure
    SomeStateEnum.FIRST_STATE   | 'param1'  | {println '1'}
    SomeStateEnum.SECOND_STATE  | 'param2'  | {println '2'}
}

解决办法是:

def 'this will work'() {
    "$someOtherPrivateMethodFromSpec"()
    "$somePrivateMethodFromSpec"()
    def resultState = service.someServiceMethod(param)

    then:
    resultState == state

    where:
    state                       | param     | method
    SomeStateEnum.FIRST_STATE   | 'param1'  | "somePrivateMethodFromSpec"
    SomeStateEnum.SECOND_STATE  | 'param2'  | "someOtherPrivateMethodFromSpec"
}

private def somePrivateMethodFromSpec() {
    someServiceMock.demand.AAA() {}
}

private def someOtherPrivateMethodFromSpec() {
    someServiceMock.demand.BBB() {}
}

为了调用闭包方式，您只需要在 where 子句中的闭包周围添加更多括号。

例如。 ({ println("1") })

或者作为完整的规范。

def 'or maybe something like this?'() {
    when:
    closure.call()
    def resultState = service.someServiceMethod(param)

    then:
    resultState == state

    where:
    state                       | param     | closure
    SomeStateEnum.FIRST_STATE   | 'param1'  | ({println '1'}) 
    SomeStateEnum.SECOND_STATE  | 'param2'  | ({println '2'})
}
