Concept

1. injector
2. make html report

Step-by-Step

1. checkout the code(include jinjector_tool and jinjector_mobile)

• svn checkout http://jinjector.googlecode.com/svn/trunk/ jinjector-read-only
  • jinjector_tool : you can build jinjector by yourself
  • jinjector_mobile : run the example

2. get the related lib from web by script

./adddextrapackagesandifiles.sh (copy from jinjector_mobile/)

requirement tool on lib/ google-collect-snapshot-20090211.zip junit3.8.1.zip easymock2.4.zip easymockclassextension2.4.zip clib-2.2.jar

3. modify the build.xml

build-yourprojectname.xml -> build.xml:

• <property name="WTK" value ="c:\wtk2.6" /> -> change the value into your WTK folder
• <property name="emulator.device" value="DefaultColorPhone" /> -> you can change device by setting this value

jinjector.yourprojectname.properties:

• jars: c:/wtk2.6/lib/cldcapi10.jar... -> your_WTK_folder/lib/cldcapi10.jar...

4. put your source and test case

jinjector_mobile\src : your source
jinjector_mobile\tests_to_inject : your test case

also you can change the value of srcdir:

<target name="injectiontests" depends="unittests"  description="Compiles the tests to inject"> <javac srcdir="${basedir}/tests_to_inject" ... ... ... <target name="compile" depends="debug_ant, extract"  description="Compiles the source"> <javac srcdir="${basedir}/src" ...

5. build test case with jinjector

ant build

• it can auto run the emulator from WTK
  
  figure. auto run the emulator from WTK

figure. end of test and output the log of coverage

hint: the log will put in here in experiential

lcov file place on Windows 7 direction: {UserDir}/j2mewtk/{WTK_Version}/appdb/{Device_Name}/filesystem/root1/{Log_Name} example: C:/Users/prada.hsiung/j2mewtk/2.5.2/appdb/DefaultColorPhone/filesystem/root1/qq.lcov

lcov file place on Ubuntu 10 direction: ~/j2mewtk/{WTK_Version}/appdb/{Device_Name}/filesystem/roo example: /home/prada/j2mewtk/2.5.2/appdb/DefaultColorPhone/filesystem/root1/qq.lcov

6. generate report html

• copy the lcov file into the "/src" where is your source folder
• generating the report html by genhtml command
• genhtml qq.lcov*
• open the index.html in the same folder
  
  
  figure. the main page show the percentage of code coverage for each class

figure. under light the code by different color. orange=coverage, red=not coverage yet in the test case
