在 MUNIT 2.0 中验证两个 JSON 有效负载时出现问题答案

【问题标题】：Issues while validating the two JSON payloads in MUNIT 2.0在 MUNIT 2.0 中验证两个 JSON 有效负载时出现问题
【发布时间】：2019-04-10 05:11:10
【问题描述】：

我有一个返回以下 json 有效负载的服务：

{

  "location-details": {

    "fromPostalCode": "1508XB",

    "fromGeoCoordinates": "116532,496398",

    "toPostalCode": "1511MA",

    "toGeoCoordinates": "120427,493380"

  },

  "commute-distance": "5817.799",

  "commute-time": "370.0152"

}

我已经创建了一个 MUNIT 测试套件，用于使用断言该实用程序断言有效负载的相同位置。片段如下：

<munit:validation >
<munit-tools:assert-that doc:name="Assert That Status Code is 200" doc:id="1c2e536b-513e-4b76-958b-2ea864a64805" expression="#[attributes.statusCode]" is="#[MunitTools::equalTo(200)]" message="The HTTP Status code is not correct!" />
<munit-tools:assert-that doc:name="Assert That - Payload is Expected" doc:id="f4b811fa-ff11-4746-93cc-f87576504808" expression="#[payload]" is="#[MunitTools::getResourceAsString('SuccessResponse.json')]" message="The response payload is not correct!"/>
</munit:validation>

但这会引发以下错误并且无法正常工作：

【解决方案1】：

您的表达式中缺少匹配器组件，请按如下方式更改并重试：

&lt;munit-tools:assert-that doc:name="Assert Payload is Correct" doc:id="5b45470f-05e8-406e-9d44-877ff1506220" expression='#[output application/json ---  write(payload, "application/json")]' is="#[output application/json --- MunitTools::equalTo(MunitTools::getResourceAsString('json\SuccessResponse.json'))]" message="The message is not correct"/&gt;

这肯定行得通！

【解决方案2】：

我不得不使用readUrl 而不是MunitTools::getResourceAsString 来比较MUNIT 2.1

中的两个JSON 对象

<munit-tools:assert-that doc:name="Assert That - JSON compare" doc:id="2fab5bf0-a710-4619-a7a9-262a867e0ad9" expression="#[payload]" is="#[MunitTools::equalTo(readUrl('classpath://sample_data/test_payload.json', 'application/json'))]" message="payload is not correct" />
