如何匹配MockMvc Spring测试中的对象列表？

Question

我有一个返回对象列表的MockMVC测试。我正在尝试检查此特定属性是否设置正确。

然而，除了显式添加之外，我无法用任何方式使它匹配。KeyPair是一个简单的Pair类，有一个键值，非常类似于一个映射的条目。

     List<KeyPair<String, String>> keyList = User.getContactDetails()
        .entrySet()
        .stream()
        .map( e -> new KeyPair<String, String>( e ) )
        .collect( Collectors.toList() );

      performQueryWithHeaders( get( "/users/1" ) )
            .andExpect( status().isOk() )
            .andExpect( jsonPath( "$.contactDetails" ,
                  is( keyList ) ) );

我尝试了几种选择

is（ keyList ）

is（ keyList.toString（） ）

是（Gson.toJson（keylist）

is(mapper . writevalueasstring(key list)(杰克逊序列化)

然而，不断得到不同的不匹配信息:

    JSON path "$.contactDetails"
Expected: is "[{\"key\":\"example title\",\"value\":\"example title\"},    {\"key\":\"another example\",\"value\":\"another example\"},{\"key\":\"etc \",\"value\":\"etc \"}]"
     but: was <[{"key":"example title","value":"example title"},{"key":"another example","value":"another example"},{"key":"etc ","value":"etc "}]>

 JSON path "$.contactDetails"
Expected: is <[KeyPair(key=example title, value=example title), KeyPair(key=another example, value=another example), KeyPair(key=etc , value=etc )]>
 but: was <[{"key":"example title","value":"example title"},{"key":"another example","value":"another example"},{"key":"etc ","value":"etc "}]>

 JSON path "$.contactDetails"
Expected: is "[KeyPair(key=example title, value=example title), KeyPair(key=another example, value=another example), KeyPair(key=etc , value=etc )]"
 but: was <[{"key":"example title","value":"example title"},{"key":"another example","value":"another example"},{"key":"etc ","value":"etc "}]>

 JSON path "$.contactDetails"
Expected: is "[{\"key\":\"example title\",\"value\":\"example title\"},{\"key\":\"another example\",\"value\":\"another example\"},{\"key\":\"etc \",\"value\":\"etc \"}]"
 but: was <[{"key":"example title","value":"example title"},{"key":"another example","value":"another example"},{"key":"etc ","value":"etc "}]>

我不想在测试中写json，因为看起来有点垃圾/脆弱。有人知道如何绘制地图吗？

Answer 1

试试这个

performQueryWithHeaders( get( "/users/1" ) )
            .andExpect( status().isOk() )
            .andExpect( gson.toJson(jsonPath( "$.contactDetails") ,
                  is( gson.toJson(keyList ) ) );

问题似乎如下所示< code > JSON path($。contactDetails")返回JsonObject类型的结构，而< code > gson . to Json(key list)返回一个字符串，该字符串包含对引号进行转义的Json。

问题是 JsonPath 将 $.contactDetails 解析为字符串，并将其与 List 进行比较

在解析$. contact细节列表的情况下，我可以建议Gson库

import java.lang.reflect.Type;
import com.google.gson.reflect.TypeToken;
// ...
Type listType = new TypeToken<List<KeyPair<String, String>>>() {}.getType();
List<KeyPair<String, String>> yourList = new Gson().fromJson(JsonPath.parse("$.contactDetails")), listType);
