Question

这是我对特定请求的答复

{
    "data": {
        "foo": [{
            "total_value":200,
            "applied_value": [{
                "type": "A",
                "id": 79806,
                "value": 200
            }]
        }]
    }
}

这是我对 SAME 请求

的另一个答复

{
    "data": {
        "foo": [{
            "total_value":300,
            "applied_value": [{
                    "type": "A",
                    "id": 79806,
                    "value": 200
                },
                {
                    "type": "B",
                    "id": 79809,
                    "value": 100
                }
            ]
        }]
    }
}

我不确定我会针对哪种情况做出回应所以用例是每当 applied_value 中有2个值时，添加两个值并声明每当 applied_value 中只有1个值时，直接声明

Answer 1

这是一种可能的解决方案：

* def adder = function(array) { var total = 0; for (var i = 0; i < array.length; i++) total += array[i]; return total }
* def response =
"""
{
    "data": {
        "foo": [{
            "total_value":300,
            "applied_value": [{
                    "type": "A",
                    "id": 79806,
                    "value": 200
                },
                {
                    "type": "B",
                    "id": 79809,
                    "value": 100
                }
            ]
        }]
    }
}
"""
* def expected = get[0] response..total_value
* def values = $response..value
* def total = adder(values)
* match expected == total

仅作为示例，实现adder例程的另一种方法是这样的：

* def total = 0
* def add = function(x){ karate.set('total', karate.get('total') + x ) }
* eval karate.forEach(values, add)
