使用junit5 assertAll 断言黄瓜数据表列表地图

Question

我在黄瓜步骤定义中有这个

 secondIT.jsonPathEvaluator = secondIT.response.jsonPath();

然后在另一个步骤 def 中，我断言，我有

  public void employee_response_equals(DataTable responseFields){
              List<Map<String,String>> fields = responseFields.asMaps(String.class,String.class);
              Iterator<Map<String, String>> it = fields.iterator();
              while (it.hasNext()) {
                     Map<String, String> map = it.next(); 
                    for (Map.Entry<String, String> entry : map.entrySet()) {
                      System.out.println(entry.getKey() + " = " + entry.getValue());
                      assertEquals(secondIT.jsonPathEvaluator.get(entry.getKey()), entry.getValue());
                     assertAll(
                        // how to use this instead
                );
                    
                 }
             }
            
        }

如何使用 junit5 assertAll 断言每个键获取的值（来自 jsonPathEvaluator）和来自映射的值

我尝试使用assertEquals，但我不确定这是否正确，因为它只打印一些信息，即key = data.id，当我评论该行时，它会打印所有内容

key = data.id
value = 2
key = data.employee_name
value = Garrett Winters

另外，我遇​​到了this，但我不确定如何为我的场景制作可执行文件

样本数据表：

  And response includes the following employee info
       |key                         |value| 
       | data.id                    | 3 |
       | data.employee_name         | Garrett Winters   |

和示例响应：

{
    "status": "success",
    "data": {
        "id": 2,
        "employee_name": "Garrett Winters",
        "employee_salary": 170750,
        "employee_age": 63,
        "profile_image": ""
    },
    "message": "Successfully! Record has been fetched."
}

assertAll 是错误的工作工具。仅当您确切知道要断言多少事物并且可以对它们进行硬编码时，它才有效。你可能想看看使用断言库，例如AssertJ。

在使用 AssertJ 之前，必须将问题简化一点。

您可以在步骤中从数据表中删除标题：

    And response includes the following employee info
      | data.id            | 3               |
      | data.employee_name | Garrett Winters |

然后可以tell Cucumber you want this data as map by changing the DataTable to a map。 Cucumber 会告诉你它是否无法满足你的需求。

@Then("response includes the following employee info")
public void employee_response_equals(Map<String, String> expectedFields){

一旦您将信息作为地图，您就可以使用预期的键从 json 响应中收集所有键。

Map<String, Object> actualFields = expectedFields.keySet()
    .stream()
    .collect(Collectors.toMap(expectedKey -> expectedKey, expectedKey -> jsonPathEvaluator.get(expectedKey)));

然后你可以使用 AssertJ 的assertThat 来比较两张地图。

assertThat(actualFields).containsAllEntriesOf(expectedFields);

当字段不匹配时，您会收到一条很好的消息：

java.lang.AssertionError: 
Expecting map:
 <{"data.employee_name"="Nora Jones", "data.id"="3"}>
to contain:
 <[data.id=3, data.employee_name=Garrett Winters]>
but could not find the following map entries:
 <[data.employee_name=Garrett Winters]>
