1. 下载 cobertura-1.9.4.1.zip
2. 将cobertura.jar、lib下的jar包copy到$TOMCAT_HOME/lib下。
3. 将coberturaFlush.war copy到$TOMCAT_HOME/webapps下。
4. 编写build.properties
# The source code for the examples can be found in this directory src.dir=/home/a/project/src/mbr_luna_subway_20120221_jan/subway-biz/src # The path to cobertura.jar cobertura.dir=/home/a/project/cobertura-1.9.4.1 # Classes generated by the javac compiler are deposited in this directory classes.dir=/home/a/project/subway-bizservice/WEB-INF/classes # Instrumented classes are deposited into this directory instrumented.dir=/home/a/project/src/bak # All reports go into this directory reports.dir=/home/a/project/result # Coverage reports are deposited into these directories coverage.html.dir=${reports.dir}/cobertura-html #server.bin.dir=/usr/local/dev-tomcat2.0-api-mobile/bin server.bin.dir=/home/a/project/tomcattop_bserv/bin serName=cobertura.ser #flush url flush.url=http://10.232.132.58:47080/coberturaFlush/flushCobertura coverage.xml.dir=${reports.dir}/cobertura-xml coverage.summaryxml.dir=${reports.dir}/cobertura-summary-xml coverage.html.dir=${reports.dir}/cobertura-html
注意:flush.url 是你要测试的tomcat下对应的coberturaFlush.war中的servlet
5.编写build.xml

6. 运行命令ant。原理:
1)将待统计的代码的class文件重新生成class,添加了统计代码的代码。
2) 运行测试用例时,会将内容统计到$TOMCAT_HOME/bin/cobertura.ser中。
3) 运行结束之后,通过调用http://10.232.132.58:47080/coberturaFlush/flushCobertura,将serverlet中统计到的信息序列化到cobertura.ser文件中。
4) 最后通过cobertura-report.sh 这个命令生成报告。
7. 运行测试用例。
8. 重新运行ant命令,生成测试报告。
