单元测试是对最小单元即方法的测试,要隔离对他模块的依赖,一般采用stub和mock两种方式
集成测试是对功能的测试,对于大部分web模块来说需要启动web容器,进行集成测试
maven生命周期中已经包含测试(test)和集成测试(integration-test),但未对两种测试代码做区分,需要自己解决启动web容器和代码区分问题。
首先配置mavenjetty插件在集成测试阶段自动启动
<plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>maven-jetty-plugin</artifactId> <version>6.1.10</version> <configuration> <stopPort>9966</stopPort> <stopKey>stop-jetty-for-it</stopKey> <contextPath>/SDKAuth</contextPath> <scanIntervalSeconds>10</scanIntervalSeconds> <jettyEnvXml>${basedir}/src/test/resources/jetty-env.xml</jettyEnvXml> </configuration> <executions> <execution> <id>start-jetty</id> <!--集成测试前启动jetty--> <phase>pre-integration-test</phase> <goals> <goal>run</goal> </goals> <configuration> <daemon>true</daemon> </configuration> </execution> <execution> <id>stop-jetty</id> <!--集成测试结束停止jetty--> <phase>post-integration-test</phase> <goals> <goal>stop</goal> </goals> </execution> </executions> </plugin>
然后测试代码进行单元测试和集成测试区分,一般有两种方式:
一是使用mavenprofile,通过profile区分
二是根据生命周期,配置mavensurefire插件不同生命周期的includes或/exclueds属性
我使用的方式二,在src/test/java目中把单元测试代码放在unit包,集成测试代码放在integration包,具体配置如下:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.9</version> <configuration> <skip>true</skip> </configuration> <executions> <execution> <id>run-integration-test</id> <phase>integration-test</phase> <goals> <goal>test</goal> </goals> <configuration> <skip>false</skip> <includes> <include>**/integration/**/*.java</include> </includes> </configuration> </execution> <execution> <id>run-test</id> <phase>test</phase> <goals> <goal>test</goal> </goals> <configuration> <skip>false</skip> <includes> <include>**/unit/**/*.java</include> </includes> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.0</version> <configuration> <dependentWarExcludes>WEB-INF/lib</dependentWarExcludes> </configuration> </plugin> </plugins>
可以参考http://docs.codehaus.org/display/MAVENUSER/Maven+and+Integration+Testing
运行集成测试命令:mvnintegration-test
