SpringMVC / mockMVC / jsonpath比较字符串列表 [英] SpringMVC/ mockMVC/ jsonpath compare list of strings
问题描述
我目前正在为Spring MVC项目编写一些单元测试。
由于返回的媒体类型是JSON,我尝试使用jsonPath来检查是否返回了正确的值。
I am currently writing some unit tests for a Spring MVC project. As the returned media type is JSON, I try to use jsonPath to check if the correct values are returned.
我遇到的麻烦是验证是否字符串列表包含正确的(并且只有正确的)值。
The trouble I have is to verify if a list of strings contains the correct (and only the correct) values.
我的计划是:
- 检查列表是否具有正确的长度
- 对于应该返回的每个元素,检查它是否在列表中
遗憾的是,这些似乎都不起作用。
sadly, none of these things seem to work.
这是我的代码的相关部分:
Here's the relevant part of my code:
Collection<AuthorityRole> correctRoles = magicDataSource.getRoles();
ResultActions actions = this.mockMvc.perform(get("/accounts/current/roles").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk()) // works
.andExpect(jsonPath("$.data.roles").isArray()) // works
.andExpect(jsonPath("$.data.roles.length").value(correctRoles.size())); // doesn't work
for (AuthorityRole role : correctRoles) // doesn't work
actions.andExpect(jsonPath("$.data.roles[?(@=='%s')]", role.toString()).exists());
只有前两个期望(isOk& isArray)才有效。其他的(长度和内容)我可以扭曲和转动但是我想要,他们没有给我任何有用的结果。
Only the first two "expectations" (isOk & isArray) are working. The other ones (for length and content) I can twist and turn however I want, they're not giving me any useful result.
有什么建议吗?
推荐答案
1)而不是
.andExpect(jsonPath("$.data.roles.length").value(correctRoles.size()));
尝试
.andExpect(jsonPath("$.data.roles.length()").value(correctRoles.size()));
或
.andExpect((jsonPath("$.data.roles", Matchers.hasSize(size))));
2)而不是
for (AuthorityRole role : correctRoles) // doesn't work
actions.andExpect(jsonPath("$.data.roles[?(@=='%s')]", role.toString()).exists());
尝试
actions.andExpect((jsonPath("$.data.roles", Matchers.containsInAnyOrder("role1", "role2", "role3"))));
请记住,你必须添加hamcrest-library。
Keep in mind that you have to add hamcrest-library.
