使用变量而不是文字的Spock检查调用

Question

class SomeSpec extends Specification {

    Map message

    String topicArn = "aws::fake-sns-topic"

    def 'test new message'() {
        when: 'A new message is received'
        message = [
                "ownerToken": null,
                "status": "NEW"
        ]
        def response = api.doHandleRequest(message)

        then: 'It is handled'
        1 * snsClient.publish(topicArn, JsonOutput.toJson([
                "ownerToken": null,
                "status": "NEW"
        ]))
    }
}

1 * snsClient.publish(topicArn, message)

Too few invocations for:

1 * snsClient.publish(topicArn, JsonOutput.toJson(message))   (0 invocations)

Unmatched invocations (ordered by similarity):

1 * snsClient.publish('aws::fake-sns-topic', '{"ownerToken":null","status":"NEW"}')
One or more arguments(s) didn't match:
0: <matches>
1: argument == expected
   |        |  |
   |        |  null
   |        false
   {"ownerToken":null,"status":"NEW"}

Answer 1

我更愿意将断言更改为

1 * snsClient.publish(topicArn, message)

好吧，它不能那样工作。正如您发布的测试错误所暗示的，您真正想要的是

1 * snsClient.publish(topicArn, JsonOutput.toJson(message))

从而导致您在测试过程中看到的异常。

def 'new message gets published'() {
  given: 'a new message'
  message = [
    "ownerToken": null,
    "status"    : "NEW"
  ]

  when: 'the message is received'
  def response = api.doHandleRequest(message)

  then: 'it gets published'
  1 * snsClient.publish(topicArn, JsonOutput.toJson(message))
}
