Hi John,

 

Could you please let me know the procedure to get the code coverage of the jar file which is not added in the classpath, but loaded dynamically using class loader and invoked using java reflection.

Is there a reason you can't just add the name of the JAR file to the
classpath you define in the ant script (or maven pom) that runs the
coverage tool? It doesn't have to be on the compilation classpath,
just the execution classpath of Cobertura itself.

Hi Jim,

Yes jim the application is designed such way, I cannot amend it.

* normal execution (without coverage), will not have the jar file in
class path, instead loaded dynamically.

Will this work ??

* instrument  this jar, into instrument folder.
* set this instrument folder in class path before execution.

Hi Jim,


Please find the attached test program, I have tested reflection and
cobertura.
In the public class there are two methods withoutreflection and
reflection both invokes same method from another class, the code
coverage works fine with withoutreflection but not with reflection.
Please suggest me some solution.

Please also include the ant script or maven pom you are using to drive
Cobertura.

Also, I'm not the best person to investigate this--I'm not a Cobertura
developer, just a user of the tool.

By the way, the comments in the code are backwards from your email.

The comments say:

        RestrictedURLClassLoader1.reflection();           // code is
covered with cobertura

        RestrictedURLClassLoader1.withoutreflection();   //  code is
not covered with cobertura

but the email says:

the code coverage works fine with withoutreflection but not with
reflection.
