比较 Postman 中的整个响应主体,同时它具有 JSON DataSchema

Comparing entire response body in Postman, while it has JSON DataSchema

我对 Postman 很陌生,正在尝试创建自动化脚本来创建包含 JSON 架构的对象。但是我收到一个错误,我不确定如何绕过。

你能帮忙吗?

这是我预期的响应脚本:

    pm.test("Body is correct", function () {
    pm.response.to.have.body("{\"Id\":"+typeId+",\"NamespaceId\":"+namespaceId+",\"Name\":\"Auto Test\",\"DataSchema\":\"\{\n    \"firstName\": {\n           \"type\": \"string\",\n           \"description\": \"The person\u0027s first name.\"\n    \}\n}\",\"Code\":\"AUTOTYPE\"}");
});

这是实际的回复(正文):

    {
    "Id": 1059,
    "NamespaceId": 1089,
    "Name": "Auto Test",
    "DataSchema": "{\r\n  \"firstName\": {\r\n    \"type\": \"string\",\r\n    \"description\": \"The person's first name.\"\r\n  }\r\n}",
    "Code": "AUTOTYPE"
}

这是我遇到的错误:

Body is correct | AssertionError: expected response body to equal '{"Id":1059,"NamespaceId":1089,"Name":"Auto Test","DataSchema":"{\n "firstName": {\n "type": "string",\n "description": "The person\'s first name."\n }\n}","Code":"AUTOTYPE"}' but got '{"Id":1059,"NamespaceId":1089,"Name":"Auto Test","DataSchema":"{\r\n \"firstName\": {\r\n \"type\": \"string\",\r\n \"description\": \"The person\u0027s first name.\"\r\n }\r\n}","Code":"AUTOTYPE"}'

下面是创建脚本的实际部分:

    {  "NamespaceId": 1089,
  "Name": "Auto Test",
  "Code": "AUTOTYPE",
  "DataSchema": {
    "firstName": {
           "type": "string",
           "description": "The person's first name."
    }
}
 }

提前致谢。

P.S。我试着放更多 \ 但 Postman 会抱怨。

您的测试中有很多空格。尝试:

pm.response.to.have.body("{\"Id\":"+typeId+",\"NamespaceId\":"+namespaceId+",\"Name\":\"AutoTest\" ,\"DataSchema\":\"{\n"firstName\": {\n"type\": \"string\",\n"description\": \"The person\u0027s firstname.\"\ n}\n}\",\"Code\":\"AUTOTYPE\"}");

我认为问题在于您指定希望将字符串作为正文,而不是将其与 JSON 对象进行比较。您现在设置的方式,测试非常脆弱,恕我直言。

多一点编码会给你一个更稳定的解决方案(例如,不依赖于空白格式,这与 JSON 无关):

pm.test("Body is correct", function () {
    const jsonData = pm.response.json();
    pm.expect(jsonData.Id)
        .to.be.a('number', 'Id should be a number')
        .that.is.equal(typeId, 'Id should equal typeId');
    pm.expect(jsonData.NamespaceId)
        .to.be.a('number', 'NamespaceId should be a number')
        .that.is.eql(namespaceId);
    pm.expect(jsonData.Name).to.equal("Auto Test");  

    // is this really what you want, i.e. should this be a string?
    pm.expect(jsonData.DataSchema).to.be.a('string'); 
    const dataSchema = JSON.parse(jsonData.DataSchema);
    pm.expect(dataSchema.firstName.type).to.equal("string");
    // ... etc    
});
