Springboot单元测试

第一步：引入依赖

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

<dependency>
   <groupId>junit</groupId>
   <artifactId>junit</artifactId>
   <version>4.12</version>
   <scope>test</scope>
</dependency>

第二步：编写test类

package com.lpf;

import com.lpf.grainmall.product.entity.BrandEntity;
import com.lpf.grainmall.product.service.BrandService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
//扫描指定包下面的类加入到Spring容器
@ComponentScan(basePackages = "com.lpf")
@SpringBootTest(classes = GrainmallProductApplicationTests.class)
public  class GrainmallProductApplicationTests {

	@Autowired
	private BrandService brandService;

	/**
	 * 注意：引入 org.junit包下面的test，不要搞错包！！！
	 */
	@Test
	public void contextLoads() {

		BrandEntity brandEntity = new BrandEntity();
		brandEntity.setName("小米");
		brandEntity.setDescript("性价比超高");
		boolean save = brandService.save(brandEntity);
		System.out.println(save);

	}

}
