Cobertura showing wrong line coverage

Question

I see a strange cobertura report. It says that line number 89 (see screenshot)

siteMapItems = getItemFromPage(navParentPage, 0);

is executed once, but the method called on this line (getItemFromPage) shows no line coverage. I have also added logs in the method and i also see logs being printed during execution of unit test case.

What could be the reason of this strange report? Its not making sense to me.

It seems to me that an exception is getting thrown when line 90 is executed by the test. Maybe there is a bogus "catch (Exception e) {}" somewhere? – Chino

@Rogério: No, there is no catch (Exception e ..) code anywhere. Also, if you see line 122 (LOG.info...). The logs get printed correctly. – Gendron

If no exception is ocurring, I see no reason for the red lines... Maybe it's some bug in the Cobertura tool? If possible, you could try a different tool, such as JaCoCo. – Chino

Can you upload a repro case somewhere? – Beamon

Probably you only need to clean the project(delete all generated files, classes, etc) and then compile it again. Finally run the test again. – Isabellaisabelle

@Gendron were you able to find the root cause for this issue? I'm also facing the same. – Gynaecomastia

@Coder: No, never found solution, seems like a issue with cobertura. – Gendron

Answer 1

Occasionally this kind of desynchronization issues arise from mismatch of java files and class files. Check if cobertura is scanning right class file.
