Re: [Cobertura-devel] Need info on instrumenting via command line

[John W. L. <Joh...@sa...>]

Try this:

./cobertura-instrument.sh --destination /ariba/9r2_sourcing/Instrument /ariba/9r2_sourcing/roots-S49r2/install/classes

Make sure you don't instrument classes twice (delete the contents of the instrument dir before the command).   I would also delete the cobertura.ser file if it exists before instrumentation.

Subject: Need info on instrumenting via command line

Hi,

I am using Corbetura-2.0.3 with java 1.7 and I am trying to instrument the classes in our build system via command line.  Stuck at instrumenting classes.   Please assist.

Here is the command:
./cobertura-instrument.sh --basedir /ariba/9r2_sourcing/roots-S49r2/install/classes/ariba.app.approvable.zip --destination /ariba/9r2_sourcing/Instrument -auxClasspath /ariba/9r2_sourcing/roots-S49r2/install/classes

Wherein,
 /ariba/9r2_sourcing/roots-S49r2/install/classes/ariba.app.approvable.zip - zip containing classes which I would like to instrument
/ariba/9r2_sourcing/Instrument - Folder to save instrumented classes
/ariba/9r2_sourcing/roots-S49r2/install/classes - path where all other reference classes are present.

Output:
-bash-4.1$ ./cobertura-instrument.sh --basedir /ariba/9r2_sourcing/roots-S49r2/install/classes/ariba.app.approvable.zip --destination /ariba/9r2_sourcing/Instrument -auxClasspath /ariba/9r2_sourcing/roots-S49r2/install/classes

Also tried with :

Re: [Cobertura-devel] command-line scripts, what am I doing wrong?

[John W. L. <Joh...@sa...>]

Try
java -cp $CP net.sourceforge.cobertura.instrument.InstrumentMain --failOnError /tmp
This will instrument the classes under /tmp.   Make sure you do not instrument classes that have already been instrumented.   I would delete the cobertura.ser file before instrumenting if it exists.

Now, consider the following trivial java class:

Can't get much simpler than that.

Now, IIUC, to instrument class Foo, I have to run:

More to the point, it doesn't matter if I list a nonexistent class instead of Foo, I still get the same output, which leads me to believe that InstrumentMain is ignoring it completely. What am I doing wrong?

Re: [Cobertura-devel] scripts in 2.0.3 distribution are wrong

[Jeff J. <jj...@ap...>]

I've never used those scripts - I've always run Cobertura with build, e.g.
Maven or in IDE.  My guess is most others too.

[Cobertura-devel] Examples of use?

[J <mc...@gm...>]

The scripts don't work for me.

to run my original tests, I would say:

java -cp $SOMEPATHWITHLOTSOFJARS com.foo.bar.my.class.Main

what do I do to instrument, run, and report?

java -cp $COBERTURAPATHS com.sourceforge.net.instrument.Main -cp
SOMEPATHWITHLOTSOFJARS com.foo.bar.my.class.Main

doesn't work.

[Cobertura-devel] Checking on pull request #102

[Bill H. <bha...@ap...>]

Hello Coberturans,

I submitted pull request #102 back in early December:

https://github.com/cobertura/cobertura/pull/102

Any chance it might be accepted soon? It seems it would resolve a couple of
open issues, and some other pull requests have already been closed in favor
of it. Having it would also help the Apache Accumulo team with its use of
Cobertura.

Thanks!

Re: [Cobertura-devel] how do I *build* cobertura from source?

[Steve C. <sch...@gm...>]

You can build the cobertura jar by running `mvn package` which will
generate the binaries in the target directory. Or you could go to the
CI server and download the snapshot version:

Re: [Cobertura-devel] knock-knock, is this thing on?

Last I checked this project wasn't dead...In fact there was a commit
that was made 5 days ago to migrate to asm 5. A lot of waiting on my
part was for asm 5 to be an official release and for java 8 to become
GA.

[Cobertura-devel] JDK7 support? Wikipedia says no!

According to http://en.wikipedia.org/wiki/Java_Code_Coverage_Tools

[Cobertura-devel] Zero % coverage in maven multi module setup

[Ankur J. <an...@gm...>]

Hi,

Have a query regarding cobertura-maven. Any help is appreciated.

I could integrate cobertua with maven.
But when I run mvn cobertura:cobertura the report generated shows 0%.

The project has multiple modules like:
./project
|-pom.xml
|-project-api
| |- pom.xml
|-project-impl
| |- pom.xml
|-unit-tests
| |- pom.xml

What steps need to be followed when running cobertura with maven for a
projct having multiple modules.

Note that it worked when I placed the test case class inside the actual
source project i.e. inside project-api. But I do not want to structure it
that way.

Thanks,
Ankur

[Cobertura-devel] Need to understand why "<CoberturaModifiedClass>.getClass().getDeclaredFields()" gets only "__cobertura_counters"

[KARR, D. <dk...@at...>]

I'm looking at an existing test with very questionable code, which uses reflection to get all the declared fields of the CUT, attempting to create mock instances of all of them.  Without Cobertura, it gets the expected list of declared fields.  With Cobertura, it doesn't get the declared fields of the class, it only gets a single field "int[] __cobertura_counters".  I tried both "ClassName.class.getDeclaredFields()" and "instance.getClass().getDeclaredFields()".

I need to understand what's going on here.  Despite the dubious nature of what it's doing, is it possible to have the Cobertura-processed code get the original list of declared fields of the CUT?

[Cobertura-devel] Testing Cobertura against JDK 8 EA builds

Hi,

I am from the OpenJDK Quality Group at Oracle.  I am working with Open 
Source projects
that are testing JDK 8 Early Access builds (either those published by 
Oracle <https://jdk8.java.net/download.html>, or their own)
and I would like to encourage more of it to happen.

I am looking for a contact person who is interested in working with me , 
sharing your test
experiences and any issues uncovered by testing Cobertura with JDK 8 EA 
builds. I expect
this will be of benefit to both communities.

We are now very late in the release cycle of JDK 8 , issues found late 
may be postponed to
an Update Release.

Re: [Cobertura-devel] Cobertura HTML report - colors

[John W. L. <Joh...@sa...>]

The first column is the line number in the source file.  It is never red, and it is green only if there is some executable code on it.

The second column line is green when the line and all conditionals on the line are covered.  Otherwise, it is red.  

The way to see the lines covered (ignoring the conditional coverage), you can't rely on the colors.   You need to look at the number in the second column.  It tells the number of time the line is executed.   Look for zeros.

Hi,
   I am trying to figure out the lines covered from the cobertura html report. The only documentation I could find was https://github.com/cobertura/cobertura/wiki/line-coverage-explained
which does not explain the color scheme used.

I see that some of the lines are not colored by either red or green, some with green, and some with red. Does the green indicate lines covered? I see that some of the lines are not colored either, and some are colored with first column green, and second column red, and others with first and second green. What does the first column and second column show? How do I interpret the color scheme? Any help would be really appreciated.

[Cobertura-devel] Query regarding remote access of coverage data and reset of the data

[Charalampos P. <cha...@gm...>]

Hi cobertura community,

The project that my team and I are working on requires remote collection of
the coverage data without interrupting the running service (ie. not only
collect data when JVM exits but while the application is running as well).
For instance, it could be a server socket running on a separate thread on
the application under test, accepting connections on a particular port, and
upon receiving a coverage data collection request from a client, it would
return the current coverage data. The client issuing the request to collect
data on the other hand, would collect this coverage data from the server
and merge them with existing local data (if any).

Additionally, one other requirement that we have to fulfill is that after
running a particular test, we need to collect the coverage data remotely
(as described above) and then reset the counters for the next test.
Overall, the flow should look like the following:

time
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------->

client  [start test 1] _________________________________ [end of test 1,
get coverage data request and reset]------- [ merge received data with
existing ones] --------------- [ start test 2] .....---->

|
|

|
|
server
-----------------------------------------------------------------------------
[send coverage data to client and reset current counters]
-------------------------------------------------------------------------------------------------------->

I would greatly appreciate any information as to to what degree I can
fulfill the project requirements with the existing cobertura functionality
and whether you think the effort to implement a server socket and the logic
to send the coverage data remotely and reset existing counters would be
significant (I took a look at the source code but I am not quite sure what
needs to be done yet).

Furthermore, any additional information regarding which files need to be
modified in order to reset the existing counters and what kind of
synchronization is needed to access the coverage data before sending them
remotely to the client, would be greatly appreciated.

Kind Regards,
Harry

[Cobertura-devel] Line coverage calculation between different versions

[Dmitry K. <dmi...@gm...>]

Dear Cobertura users/developers,

After I have upgraded my Cobertura from v1.9.4.1 to v2.0.3 I have
noticed that line coverage is wrong for certain classes: line is
definitely covered with unit test, but is reported as not covered.

I can't provide the clean class+text example, as the class is implicitly
tested by other unit tests. I can share maven output and generated HTML
report.

With best regards,
Dmitry
