Question

有些棘手的问题，我将尽力解释清楚。

架构：

    "dogs": {
        "dogId": "string",
        "breed": [
            {
                "canaan": true,
                "akita": false
            }
        ]
    }
}

回复：

{
    "dogs": {
        "dogId": "70872490",
        "breed": []
    }
}

功能文件：

[...] 

    And match each response.dogs contains
"""
    {
        "dogId": "##regex ^[0-9A-Za-z]*$",
        "breed": [
            {
                "canaan": "##boolean",
                "akita": "##boolean"
            }
        ]
    }
"""

错误：

path: $[0].breed[*], actual: [], expected: {canaan=##string, akita=##string}, reason: actual value does not contain expected

从上面您可以看到，breed数组有时不返回任何值，有时甚至不返回任何值，该数组可能填充了canaan或akita价值观。断言这种行为的最优雅方法是什么？我尝试了可选断言，但似乎总是希望数组值存在。

让我知道您的想法，感谢您的支持。谢谢！

示例代码：

Feature: Validation

    Scenario:
        * def isValid = function(x){ return x == "[]" || karate.match(x,karate.valuesOf([{"canaan":"#boolean","akita":"#boolean"}])).pass }    
        * def schema =
            """
            {
                "dogs": {
                        "dogId": "##regex ^[0-9A-Za-z]*$",
                        "breed": '#? isValid(_)'
                }
            }
            """         
        * def resp1 =

                        ]
                }
            }
        """
        * match resp1 == schema
        * match resp2 == schema
