package com.songhaozhi.mayday; import com.songhaozhi.mayday.model.domain.Category; import com.songhaozhi.mayday.service.CategoryService; import org.junit.Test; import org.junit.jupiter.api.Assertions; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import java.util.List; @SpringBootTest public class TestCategoryService { @Autowired CategoryService Categoryservice; @Test public void testFindCategory() { List<Category> Category = CategoryService.findCategory(); Assertions.assertEquals(5,Category.size()); } } 怎么改

你可以尝试将测试方法名从`testFindCategory()`改为更具描述性的名称，例如`testFindAllCategories()`。此外，还可以将`CategoryService`的变量名改为小驼峰命名法，即`categoryService`。修改后的代码如下所示：

package com.songhaozhi.mayday;

import com.songhaozhi.mayday.model.domain.Category;
import com.songhaozhi.mayday.service.CategoryService;
import org.junit.Test;
import org.junit.jupiter.api.Assertions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.List;

@SpringBootTest
public class TestCategoryService {
    @Autowired
    CategoryService categoryService;

    @Test
    public void testFindAllCategories() {
        List<Category> categories = categoryService.findCategory();
        Assertions.assertEquals(5, categories.size());
    }
}

这样修改后的代码更符合Java的命名规范，更易读和维护。
