Junit5 断言

JUnit5 Jupiter断言都是 org.junit.jupiter.api.Assertions 类中static方法

import static org.junit.jupiter.api.Assertions.assertAll;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertNotNull;
import static org.junit.jupiter.api.Assertions.assertNull;
import static org.junit.jupiter.api.Assertions.assertTrue;
或

import org.junit.jupiter.api.Assertions;
调用时候用
Assertions.assertAll();
Assertions.assertEquals();
Assertions.assertNotNull();
Assertions.assertNull();
Assertions.assertTrue();

Junit5 主要注解

@BeforeAll 类似于JUnit 4的@BeforeAll,表示使用了该注解的方法应该在当前类中所有使用了@Test、@RepeatedTest、@ParameterizedTest或者@TestFactory注解的方法之前执行,必须为static
@BeforeEach 类似于JUnit 4的@Before,表示使用了该注解的方法应该在当前类中每一个使用了@Test、@RepeatedTest、@ParameterizedTest或者@TestFactory注解的方法之前执行
@Test 表示该方法是一个测试方法
@DisplayName 为测试类或测试方法声明一个自定义的显示名称
@AfterEach 类似于JUnit 4的@After,表示使用了该注解的方法应该在当前类中每一个使用了@Test、@RepeatedTest、@ParameterizedTest或者@TestFactory注解的方法之后执行
@AfterAll 类似于JUnit 4的@AfterClass,表示使用了该注解的方法应该在当前类中所有使用了@Test、@RepeatedTest、@ParameterizedTest或者@TestFactory注解的方法之后执行,必须为static
@Disable 用于禁用一个测试类或测试方法,类似于JUnit 4的@Ignore
@ExtendWith 用于注册自定义扩展

IDEA 开发工具

先查看 项目src目录下是否有test/java 文件夹，
如果没有请自行创建,并设置(Project Structure -> Modules -> 你的模块)好Tests 属性目录

IDEA 快捷方式,在 需要创建单元测试的那个控制器或类上 使用如下快捷键, 会弹出一个对话框，选择Create New Test ..., 在新的对话框中，进行一些单元测试配置，Testing library 选择JUnit5,Generate 后面两个选中(根据你的需要是否要选)，Member 下 方法 ，根据你的需要选择。最后点击OK
