SpringBoot——测试

controller单元测试

AutoConfigureMockMvc

以上是针对业务层测试，如果想进行接口API测试怎么办呢，难道，开发完成每次调用postman一个个测吗？答案当然是no，不过，你也可以选择一个个测试没什么问题，如果你想通过代码实现模拟http请求就要用到我们的@AutoConfigureMockMvc注解，使用了MockMvc无需启动项目，就可实现接口测试。
以下用到的MockMvc方法介绍

• mockMvc.perform：执行请求
• MockMvcRequestBuilders.get：还支持post、put、delete等
• contentType(MediaType.APPLICATION_JSON_UTF8)：表示请求传输的Conent-Type=application/json;charset=utf-8
• accept(MediaType.APPLICATION_JSON))：客户端希望接收的Conent-Type=application/json;
• andExpect(MockMvcResultMatchers.status().isOk())：返回响应状态是否为期望的200，如果不是则抛出异常
• andReturn()：返回结果
