Json断言-错误断言失败消息：预期值与正则表达式匹配

Question

使用Jmeter执行REST API测试。当我在HTTP响应中使用JSON Path Tester并将JSON路径表达式提供为$..name时。获得以下比赛

Done,
Won't Do,
Duplicate,
Cannot Reproduce

但是当我在JSON断言中放置相同的JSON表达式和Result时，出现错误：-

Assertion error: false
Assertion failure: true
Assertion failure message: Value expected to match regexp '"Done","Won't Do","Duplicate","Cannot Reproduce"', but it did not match: '["Done","Won't Do","Duplicate","Cannot Reproduce"]'

Answer 1

匹配多个值

1. 使用JSON提取器从JSON响应中提取所有匹配的值

2. 通过以下代码使用JSR223声明：

   int nameLength = Integer.parseInt(vars.get("Name_matchNr"));
   
   String[] responseArray = new String[nameLength];
   for (int i = 0; i < nameLength; i++) {
       responseArray[i] = vars.get("Name_"+(i+1));
   }
   
   boolean test1 = Arrays.asList(responseArray).contains("Done");
   boolean test2 = Arrays.asList(responseArray).contains("Won't Do");
   boolean test3 = Arrays.asList(responseArray).contains("Duplicate");
   boolean test4 = Arrays.asList(responseArray).contains("Cannot Reproduce");
   
   if (test1 == false) {
   AssertionResult.setFailureMessage("Done not present in Response");
   AssertionResult.setFailure(true);
   }
   if (test2 == false) {
   AssertionResult.setFailureMessage("Won't Do not present in Response");
   AssertionResult.setFailure(true);
   }
   if (test3 == false) {
   AssertionResult.setFailureMessage("Duplicate not present in Response");
   AssertionResult.setFailure(true);
   }
   if (test4 == false) {
   AssertionResult.setFailureMessage("Cannot Reproduce not present in Response");
   AssertionResult.setFailure(true);
   }
   

匹配单个值

1. 使用JSON提取器提取值
2. 使用JSON断言来声明值。在Expected Value部分中输入任何单个值："Done/Won't Do/Duplicate/Cannot Reproduce"

Answer 2

如果这确实是您要实现的目标，请考虑以下JSON Assertion配置：

仅在“期望值”文本表示为假的情况下：

["Done","Won't Do","Duplicate","Cannot Reproduce"]

无论如何，这种形式的断言将是脆弱的，并且对任何JSON更改都是敏感的，即，如果匹配顺序不同，则断言将失败。因此，我宁愿建议使用The Easiest Way To Compare REST API Responses Using JMeter文章中描述的方法之一。
