Maven简单的配置Junit测试及使用简单的mock

1、maven依赖配置如下

        <dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-all</artifactId>
<version>1.9.5</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<build>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<appendAssemblyId>false</appendAssemblyId>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>RunJob</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>assembly</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.5</version>
</plugin>
</plugins>
</build>

 

 

2、编写测试代码

public class SimpleTest {
    @Test
public void test() {
        Assert.assertTrue("a".equals("a"));
    }

    @Test
public void testMock() {
        List m = mock(List.class);
        m.add(1);
        m.clear();

        verify(m).add(1);//验证执行过add(1)操作
        verify(m).clear();//验证执行过clear操作
    }

    @Test
public void when_thenReturn() {
//mock一个Iterator类
        Iterator iterator = mock(Iterator.class);
//预设当iterator调用next()时第一次返回hello，第n次都返回world
        when(iterator.next()).thenReturn("hello").thenReturn("world");
//使用mock的对象
        String result = iterator.next() + " " + iterator.next() + " " + iterator.next();
//验证结果
        assertEquals("hello world world", result);
    }
}
