SpringBoot整合Junit进行单元测试

添加依赖

  <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
  </dependency>

编写测试类

import com.sangeng.controller.HelloController;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class ApplicationTest {

    @Autowired
    private HelloController helloController;

    @Test
    public void testJunit(){
        System.out.println(1);
        System.out.println(helloController);
    }
}

注意：测试类所在的包需要和启动类是在同一个包下。否则就要使用如下写法指定启动类。

import com.sangeng.controller.HelloController;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

//classes属性来指定启动类
@SpringBootTest(classes = HelloApplication.class)
public class ApplicationTest {

    @Autowired
    private HelloController helloController;

    @Test
    public void testJunit(){
        System.out.println(1);
        System.out.println(helloController);
    }
}
