• Spring Boot中进行Junit测试


    Spring Boot新版本默认使用Junit5,pom依赖为:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.junit.vintage</groupId>
                <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    同时,测试类的Demo如下,其中@SpringBootTest表示将该类作为Spring的测试类,加载到spring容器中,必不可少。

    import static org.junit.jupiter.api.Assertions.assertEquals;
    
    import example.util.Calculator;
    
    import org.junit.jupiter.api.Test;

    import org.springframework.boot.test.context.SpringBootTest;

    @SpringBootTest
    class MyFirstJUnitJupiterTests {
    
        private final Calculator calculator = new Calculator();
    
        @Test
        void addition() {
            assertEquals(2, calculator.add(1, 1));
        }
    
    }

    如果项目中要使用旧版的Junit4,那么在pom文件中要删除掉“<exclusions>”这个对旧版本的支持,同时导入Junit4的相关依赖

    <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>

    在测试类中,不要忘了添加@Runwith(SpringRunner.class)注解,有时候@Test的导入的包也有影响,需要注意
