idea 如何快速测试

大项目，即使微服务，用@PostConstructor 或者，写main ，编译耗时，代码不纯洁。最号的方法Junit测试

这里介绍快捷的测试方法，

 

 生成代码如下：

package com.uxsino.commons.cache;


import org.junit.Test;

public class ItemTest {
    @Test
    public void test(){
        Item item = new Item();
        item.setDatas(new String ("dousil"));
        System.out.println(item.getDatas());
    }
}

　　快捷方式2 ，Alt+shift +t 可以直接生成测试类。

 

Junit 缺陷，junit 在测试的时候，无法知道我们是否使用spring 框架。更不用说，帮我们创建spring 容器了。

利用spring test 就可以很好的实现。

1. 整合junit的必备jar包

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.0.2.RELEASE</version>
</dependency>

2. 使用@RunWith注解

@RunWith(SpringJUnit4ClassRunner.class)
public class AccountServiceTest {
}

　　3. 使用ContextConfiguration 指定配置文件位置

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

　　

@ContextConfiguration 注解：

• locations 属性：用于指定配置文件的位置。如果是类路径下，需要用 classpath:表明
• classes 属性：用于指定注解的类。当不使用 xml 配置时，需要用此属性指定注解类的位置

4. 使用@Autowired 注解

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations= {"classpath:bean.xml"})
public class AccountServiceTest {
	@Autowired
	private IAccountService as ;
}

　　示例如下：

package com.uxsino.simo.collector;

import static org.junit.Assert.fail;

import org.junit.Ignore;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.ConfigFileApplicationContextInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(initializers=ConfigFileApplicationContextInitializer.class)
public class TestExecEnvironment {

	@Configuration
	 @ComponentScan("com.uxsino.simo.collector")
	public static class Config {
		@Autowired
		ExecEnvironment env;
	}

    @Test
    public void testExecEnvironment() {
        //assert (env != null);
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testGetNameSpace() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testGetEntityDomain() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testInit() {
        //NEDBStorage entitydb = new NEDBStorage();
        ExecEnvironment execEnvironment = new ExecEnvironment();
        assert (execEnvironment != null);
        execEnvironment.init();
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testDumpTasks() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testRunPatrolTask() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testStoreToDb() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testRunImmediateQueryEntityInfoIndicator() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testRunImmediateQueryStringEntityInfoIndicator() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testExecQuery() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testSubscribeValueConsumerOfIndicatorValue() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testSubscribeValueSubscriberOfQsuperIndicatorValue() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testAddTask() {
        fail("Not yet implemented");
    }

    @Ignore("Test is ignored before immplemenation")
    @Test
    public void testDeleteTask() {
        fail("Not yet implemented");
    }

    @Test
    public void testX() {

//        SSHTarget target = new SSHTarget();
//        target.host = "localhost";
//        target.port = 22;
//        target.passwordEncrypted=false;
//        target.setUsername("testcon");
//        target.setPassword("Pdf1scape");
//
//        SSHConnection conn = new SSHConnection();
//
//        conn.connect(target);
//
//        for (int i = 0; i < 5; i++) {
//            conn.execCmd("date");
//        }
//
//        conn.close();
    }

}
