程序中需要调远程获取数据时-测试用例中使用Mock造挡板数据

示例：

### 1、加依赖 ###

<dependency>
    			<groupId>org.jmockit</groupId>
    			<artifactId>jmockit</artifactId>
    			<version>1.47</version>
    			<scope>test</scope>
    		</dependency>

### 2、在工程编译启动pom中配Junit插件设置javaagent：jar包在添加依赖后写本地仓库的jar包路径即可。 ###

……
    <skiptTest>false</skiptTest>
    ……
    
    
    <build>
    		<pluginManagement>
    			<plugins>
    				<plugin>
    					<groupId>org.springframework.boot</groupId>
    					<artifactId>spring-boot-maven-plugin</artifactId>
    				</plugin>
    				
    				<plugin>
    					<groupId>org.apache.maven.plugins</groupId>
    					<artifactId>maven-surefire-plugin</artifactId>
    					<version>2.16</version>
    					<configuration>
    						<skipTests>${skiptTest}</skipTests>
    						<argLine>-javaagent:D:\maven\repository\org\jmockit\jmockit\1.47\jmockit-1.47.jar</argLine>
    						<testFailureIgnore>true</testFailureIgnore>
    					</configuration>
    				</plugin>
    			</plugins>
    		</pluginManagement>
    	</build>

### 3、被测试程序 ###

/**
     * @author wxming.
     * @date 2020-6-3.
     */
    @Service
    public class UseConfigUtils {
    
        //@Resource
        private ConfigUtils configUtils = new ConfigUtils();
    
        public String useConfig(){
            String oneConfig = configUtils.getConfig("一个配置");
            return oneConfig;
        }
    }

/**
     * @Description TODO
     * @author wxming.
     * @date 2020-6-3.
     */
    @Component
    public class ConfigUtils {
    
        public String getConfig(String name){
            System.out.println("走远程获取了");
            return "从远程获取的值";
        }
    
    }

### 4、测试用例 ###

package my.mark.mybaibaoxiang.mock;
    
    import mockit.Mock;
    import mockit.MockUp;
    import org.junit.Test;
    
    /**
     * @author wxming.
     * @Description TODO 使用Mock数据测试。
     * @date 2020-6-3.
     */
    public class MockTest {
    
        UseConfigUtils useConfigUtils = new UseConfigUtils();
        @Test
        public void mockOne(){
            //在要调用需要mock的数据之前，new一个Mock数据出来。
            new MockUp<ConfigUtils>(){
                @Mock
                public String getConfig(String name){
                    System.out.println("走mock了");
                    return "Mock数据的配置";
                }
            };
            String one = useConfigUtils.useConfig();
            System.out.println(one);
        }
    }

### 5、测试结果 ###

注掉Mock代码没有mock的：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2l0d3htaW5n_size_16_color_FFFFFF_t_70][]

用mock的：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2l0d3htaW5n_size_16_color_FFFFFF_t_70 1][]
