Faulty Line coverage(100%) in cobertura via ant?

Question

I'm using cobertura, but it is giving me 100% line coverage. It is showing only those lines of code which are executed?

Answer 1

Try removing the file cobertura.ser before running the tests.

Answer 2

You need to include the sources (or make sure, that they are included), when you use the report task:

<cobertura-report format="html" destdir="${coveragereport.dir}" srcdir="${src.dir}" />

Reference: cobertura-anttask

Otherwise cobertura cannot know, how many lines/classes actually exist and will report 100% coverage.
