如何断言数组中的数组?

How to assert array in array?

有人可以帮我在 postman 中断言数组中的数组吗?

我有这个安心的代码:

"documents": [
        {
            "fileName": "file01_guid.pdf",
            "documentType": "document",
            "parentFiles": [
                "file01.pdf"
            ]
        },
        {
            "fileName": "file02_guid.pdf",
            "documentType": "document",
            "parentFiles": [
                "file01.pdf"
            ]
        }

我需要使用此方法断言“ParentFiles”数组:

var array = [];
var range = (json_response.data.documents).length

for (var i = 0; i < range; i++)

{
 var file = json_response.data.documents[i].fileName
 var type = json_response.data.documents[i].documentType;

 array.push(file)
 array.push(type)
}

所以我可以写这样的测试:

{
    pm.expect(array).to.include("file01.pdf", "file01.pdf");
});

提前致谢

您可以通过简单地过滤和检查长度来验证 "file01.pdf" 是否存在。您还可以通过减少

更有效地构建您的 array

const json_response = {
  "data": {
    "documents": [{
      "fileName": "file01_guid.pdf",
      "documentType": "document",
      "parentFiles": ["file01.pdf"]
    }, {
      "fileName": "file02_guid.pdf",
      "documentType": "document",
      "parentFiles": ["file01.pdf"]
    }]
  }
};

const array = json_response.data.documents.reduce((acc, doc) => {
  const { fileName, documentType, parentFiles: [ pfName ] } = doc;
  return [ ...acc, fileName, documentType, pfName ];
}, []);

console.log(array);

// Exactly two instances of "file01.pdf" exist.
console.log(array.filter(val => val === "file01.pdf").length === 2);
.as-console-wrapper { top: 0; max-height: 100% !important; }

如果你只是想比较数组,你可以尝试以下方法:

const json_response = {
  "data": {
    "documents": [{
      "fileName": "file01_guid.pdf",
      "documentType": "document",
      "parentFiles": ["file01.pdf"]
    }, {
      "fileName": "file02_guid.pdf",
      "documentType": "document",
      "parentFiles": ["file01.pdf"]
    }]
  }
};

const allEqual = json_response.data.documents
  .every(({ parentFiles: [ filename ] }) => filename === "file01.pdf");

console.log(allEqual);
.as-console-wrapper { top: 0; max-height: 100% !important; }

您可以使用 foreach 循环并比较值

//store expected files in order
array=["file01.pdf","file01.pdf"]

//now forEach on each element
json_response.data.documents.forEach( (elem,index,arr)=>{
pm.expect(elem.parentFiles[0]).to.be.eql(array[index])
})

如果你只是想比较两个数组那么:

pm.expect(_.isEqual(array,array2)).to.be.true

lodash isEqual 可用于比较两个对象,如数组
