Question

我从api收到以下响应：

{
    "fieldErrors": [
        {
            "field": "firstName",
            "code": "Pattern",
            "message": "Invalid characters"
        },
        {
            "field": "repeatPassword",
            "code": "Size",
            "message": "Size must be between 6 and 64 characters"
        },
        {
            "field": "password",
            "code": "Size",
            "message": "Size must be between 6 and 64 characters"
        },
        {
            "field": "firstName",
            "code": "Size",
            "message": "Size must be between 3 and 32 characters"
        },
        {
            "field": "lastName",
            "code": "Pattern",
            "message": "Invalid characters"
        },
        {
            "field": "email",
            "code": "Size",
            "message": "Size must be between 3 and 256 characters"
        },
        {
            "field": "password",
            "code": "AmRestUser.PasswordTooWeak",
            "message": "Password is to weak (must consist of upper and lower case, digits, and can't contain first name)."
        },
        {
            "field": "phoneNo",
            "code": "order.summary.invalidPhone",
            "message": "Invalid Phone"
        }
    ],
    "isSuccess": false
}

我使用Mocha编写api测试，我想检查所有现有错误的字段

我编写以下测试：

      var selected = res.body.fieldErrors.filter(function(item){
        return (item["field"]=="firstName" && item["code"] == "Pattern"  && item["message"]=="Invalid characters"); 
      });
      assert.equal(selected.length,1);

      selected = res.body.fieldErrors.filter(function(item){
        return (item["field"]=="repeatPassword" && item["code"] == "Size"  && item["message"]=="Size must be between 6 and 64 characters"); 
      });
      assert.equal(selected.length,1);

测试对我有用，但是有很多冗余代码，在这种情况下，我应该写相同的代码八次，很难维护

现在我想编写一个函数，在参数中我可以传递json以及代码，消息和字段的名称。函数应该返回出现的次数，我该怎么办？

您没有告诉我们使用哪个断言库，但这是执行此操作的最简单方法（无需任何其他功能或映射）：

有关蔡的断言，请参见：https://developer.android.com/topic/libraries/architecture/workmanager/ 例如：assert.deepEqual(res.body, expected)

有关node.js的断言，请参见：deepEqual 例如：assert.deepStrictEqual(res.body, expected)

expected与您在第一个代码段中粘贴的对象保持一致。或者当然可以将其更改为fieldErrors数组。由您决定。

使用此方法，您仅需要维护一些错误列表即可。

Node.js中的JSON过滤器和断言功能
