第四讲 service接口的实现

package com.example.demo.service.Impl;

import com.example.demo.dataobject.ProductCategory;
import org.junit.Assert;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.Arrays;
import java.util.List;

import static org.junit.jupiter.api.Assertions.*;

@RunWith(SpringRunner.class)
@SpringBootTest
class CategoryServiceImplTest {

    @Autowired
    private  CategoryServiceImpl categoryService;


    @Test
    void findOne()  throws  Exception{
        ProductCategory productCategory= categoryService.findOne(1);
        Assert.assertEquals(new Integer(1), productCategory.getCategoryId());
    }

    @Test
    void findAll() {
       List<ProductCategory> list= categoryService.findAll();
        Assert.assertNotEquals(0, list.size());
    }

    @Test
    void findByCategoryTypeIn() {
      List<ProductCategory> productCategoryList=   categoryService.findByCategoryTypeIn(Arrays.asList(0,3));
        Assert.assertNotEquals(0, productCategoryList.size());

    }

    @Test
    void save() {
        ProductCategory productCategory=new ProductCategory("男生专享受",10);
        categoryService.save(productCategory);

    }
}
