cobertura-maven-plugin的使用也很简单,首先你要有源码,然后要有对这个源码编写的测试代码,最后在pom.xml中配置上cobertura-maven-plugin执行一行命令就可以了.
我们先来准备一个源码和测试用例:
要被测试的代码
packagecom.qyf404.learn.maven; publicclassApp{ publicintadd(inta,intb){ returna+b; } publicintsubtract(inta,intb){ returna-b; } } |
测试用例代码
packagecom.qyf404.learn.maven; importorg.junit.After; importorg.junit.Assert; importorg.junit.Before; importorg.junit.Test; importorg.junit.experimental.categories.Category; publicclassAppTest{ privateAppapp; @Before publicvoidsetUp(){ app=newApp(); } @Test publicvoidtestAdd()throwsInterruptedException{ inta=1; intb=2; intresult=app.add(a,b); Assert.assertEquals(a+b,result); } @Test() publicvoidtestSubtract()throwsInterruptedException{ inta=1; intb=2; intresult=app.subtract(a,b); Assert.assertEquals(a-b,result); } @After publicvoidtearDown()throwsException{ } } pom.xml配置如下: <?xmlversion="1.0"encoding="UTF-8"?> <projectxmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.qyf404</groupId> <artifactId>learn-maven</artifactId> <version>1.0-SNAPSHOT</version> <build> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>cobertura-maven-plugin</artifactId> <version>2.7</version> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> </dependencies> </project> |
数据都准备好了,我们执行以下maven命令mvncobertura:cobertura,执行完后会在target目录里找到site目录,用浏览器打开里面的index.html,这就是测试用例执行完后cobertura-maven-plugin得出的覆盖率报告.
