Hi, here is how JaCoCo works:
1) The JaCoCo agents instruments all classes loaded at runtime and inserts probes into them (at least one per method, but could be more depending on the control flow of the method). This data is saved to an exec files. Note that classes which are not loaded at all (missed) will not produce entries in the exec file. 2) When you create a report you define the scope of your report by providing all classes you want to see in your report. This should answer your questions: > but in case 1 there are more class files than the above 2 , so why is that > happening? Does it load whatever is in the memory? Because the agent instruments all classes loaded by the JVM. > How to exclude all unnecessary classes from the dump being collecteed by > Execution Data visitor in Case 1. You can use its “exclude” parameter to exclude certain classes for technical reasons but this does not change the scope of your report (instead classes excluded from instrumentation will show as uncovered) The correct usage of JaCoCo would be to supply only the classes you want to see in your report to the report generator.
