Spring框架下的单元测试

一、使用spring中对Junit框架的整合功能

除了junit4和spring的jar包，还需要spring-test.jar。引入如下依赖：

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.10</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>4.2.0.RELEASE</version>
</dependency>

@ContextConfiguration需要配上spring的配置文件，这样就可以在测试类中使用注解简单的注入需要的bean了。简单高效。

@ContextConfiguration({"classpath:applicationContext.xml"})
@RunWith(SpringJUnit4ClassRunner.class)
public class TestCase {

    @Autowired
    private TopProducer topProducer;
    private String topic = "lilixin";

    @Test
    public void testCase(){
        System.out.println("##############################");
        topProducer.send(topic,"this ia a kafka test msg");
        System.out.println("##############################");
    }

}

二、手动加载spring的配置文件，并启动spring容器

public class TestCase {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");

        TopProducer topProducer = (TopProducer)context.getBean("topProducer");

        topProducer.send("lilixin", "this ia a kafka test msg");
    }

}

运行这两种测试方法，EclipseIDE下都只需要Ctrl+F11。
