写测试用例都很头疼,然而对核心方法的单元测试是非常重要的.

nutz-plugins-mock 提供了 Ioc支持,Mvc环境, Servlet Mock对象

基本用法

添加依赖

    <dependency>
        <groupId>org.nutz</groupId>
        <artifactId>nutz-plugins-mock</artifactId>
        <version>1.r.60</version>
        <scope>test</scope>
    </dependency>
    <!-- 可选, 安利一下mockito,模拟mock对象很方便 -->
    <dependency>
        <groupId>org.mockito</groupId>
        <artifactId>mockito-core</artifactId>
        <version>2.6.3</version>
        <scope>test</scope>
    </dependency>

添加Runner. web项目建议覆盖getMainModule方法, 非web项目覆盖getIocArgs

public class MyNutTestRunner extends NutTestRunner {

    public MyNutTestRunner(Class<?> klass) throws InitializationError {
        super(klass);
    }

    public Class<?> getMainModule() {
        return MainModule.class;
    }
    
    /**
     * 可覆盖createIoc,实现参数覆盖, bean替换,等定制.
     */
    protected Ioc createIoc() {
        Ioc ioc = super.createIoc();
        PropertiesProxy conf = ioc.get(PropertiesProxy.class, "conf");
        conf.put("db.url", "jdbc:h2:~/test");
        return ioc;
    }
}

测试类, 请务必留意测试类所在的package,确保到ioc配置的覆盖范围内.

@RunWith(MyNutTestRunner.class)
@IocBean // 必须有
public class SimpleTest extends Assert {
    
    //private static final Log log = Logs.get();
    
    // 跟通常的@Inject完全一样.
    @Inject("refer:$ioc")
    protected Ioc ioc;
    
    @Inject
    protected Dao dao;
    
    @Test
    public void test_user_service_create_user() {
        dao.create(User.class, false);
        User user = new User("wendal", "1234512345");
        dao.insert(user);
        
        user = dao.fetch(User.class, "wendal");
        assertNotNull(user);
        assertNotNull(user.getName());
    }
}
