在 spock 验证中使用运行时变量

Question

我正在尝试编写一个简单的测试，我想用一些运行时变量验证模拟调用。目前它看起来像这样：

class Spec extends Specification implements SampleData {
EventBus eventBus = Mock()
Facade facade = new Configuration().facade(eventBus)
def "when the method is called an proper event is emitted"() {
when:
def id = facade.call(sampleData)
then:
1 * eventBus.push(_ as Event)
}
}

但是我想要实现的也是验证事件的有效载荷是否正确 - 这意味着事件包含id，如下所示：

then:
1 * eventBus.push(new Event(id))

是否有可能在斯波克实现这种验证？

您可以通过在EventBus上存根push()方法来捕获Event。

def "when the method is called a proper event is emitted"() {
given:
EventBus eventBus = Mock()
Facade facade = new Configuration().facade(eventBus)
Event received
when:
def id = facade.call(sampleData)
then:
1 * eventBus.push(_ as Event) >> { Event event -> received = event }
received.id == id
}
