cobertura-1.9.4.1结合tomcat生成测试报告

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

<?xml version="1.0" encoding="UTF-8"?>
<project name="cobertura.examples.basic" default="coverage-report" basedir=".">

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。
