由于Spring测试类上只能有一个@Runwith注解,如果使用@RunWith(Parameterized.class),就无法s使用@RunWith(SpringJUnit4ClassRunner.class)。
@RunWith(SpringJUnit4ClassRunner.class)是JUnit的注解,通过这个注解让SpringJUnit4ClassRunner 这个类提供Spring测试上下文 需要借助TestContextManager来实现上下文注入。
TestContextManager 与@RunWith(SpringJUnit4ClassRunner.class) 效果一样
在spring-framework-reference中的介绍
可以参考如下文章,利用TestContextManager来注入 Spring
参考如下java Code Examples for org.springframework.test.context.TestContextManager.prepareTestInstance
示例如下:
package com.netease.ey.pay.controller;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestContextManager;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import javax.annotation.Resource;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
@RunWith(Parameterized.class)
@SpringBootTest
@ContextConfiguration
@AutoConfigureMockMvc
public class PayControllerTest {
private static final Logger logger = LoggerFactory.getLogger(PayControllerTest.class);
@Resource
private MockMvc mockMvc;
private TestContextManager testContextManager;
@Before
public void setUp() throws Exception {
testContextManager = new TestContextManager(getClass());
testContextManager.prepareTestInstance(this);
}
@Parameterized.Parameters(name = "{index}:orderId:{0}")
public static Object[] data() {
return new Object[] { "1","7"};
}
@Parameterized.Parameter // first data value (0) is default
public /* 不能为 private */ String orderId;
@Test
public void transfer() throws Exception {
String response = mockMvc.perform(MockMvcRequestBuilders.post("/pay/transfer")
.param("orderId", orderId))
.andExpect(MockMvcResultMatchers.status().isOk()).andDo(print()) //打印出请求和相应的内容
.andReturn().getResponse().getContentAsString();
logger.info("返回值{}",response);
}
}
