Fine Tuning Reports

[joe.d...@gmail.com]

Our functional testing is currently generating code coverage reports, for all our projects. Some of our code base contains auto-generated code. This generated code contains some lines of code that we cannot reach via our functional testing. We are looking for a way exclude those lines of code from our code coverage reports.
Any ideas would be greatly appreciated.

Hi,

filtering single lines from reports is currently not supported in
JaCoCo. Future versions of JaCoCo might provide diffeent kind of filters
to do so, we described use cases here:
https://github.com/jacoco/jacoco/wiki/FilteringOptions

Best regards,

We would happily implement our own filtering, is there a particular class we should be overriding or modifying?
The reporting examples perform three steps:
- loading the execution data
- analysis
- report generation

If there are particular source code patterns that we want to ignore, what class(es) should be modified to implement the ability to ignore that code.

[Marc R. Hoffmann]

Hi,

to be honest: If I could answer your questions filtering would have
already been implemented ;-)

JaCoCo does not process any source code, it only works on class files. I
would prefer to stick with this paradim also for filters.

Best regards,

If we come up with anything,  I'll let you know.

We have been able to update the Line Counts in CoverageBuilder.visitCoverage
We use the coverage object to get the line counter, and increment accordingly. However in the html report the missed lines total is still unchanged, even though the the values for each row in the table is correct.
How are these totals generated?
Is there another counter to update.

[Marc R. Hoffmann]

All totals are created with the CoverageNodeImpl.increment() methods.

Thanks, we'll give it a try .

[Joe Damore]

In CoverageBuilder.visitCoverage( final IClassCoverage coverage )  , can I get access to CoverageNodeImpl ?

[Marc Hoffmann]

You can create a copy for your own purposes:

CoverageNodeImpl mynode = new
CoverageNodeImpl(coverage.getElementType(), coverage.getName());
mynode.increment(coverage);

Best regards,
