Clover: how Branch,stmt,Method and Total is calculated?

Does these calculated with respect to LOC or NCLOC?

Please help me in understanding the how the above things are calculated with some sample .java file.

Hello Sai,

Please note that Clover does not measure code coverage per source line - no matter whether we're talking about LOC or NCLOC. What Clover measures is a code coverage of real code structures, such as branches, statements and methods.

It means that you can see for instance:

• a number of statments in a method, class, package or a whole project
• a number of classes in a file, package or a whole project
• etc

You might wonder "how the statement coverage metric provided by Clover relates to the line coverage metric provided by other coverage tools such as Cobertura or EMMA". The answer is:

A single statement can span over several source lines; it is also possible to have several statements in a single source line. Therefore there is no 1:1 mapping between a statement coverage and a line coverage. Nevertheless, both metrics provide a similar granularity of a coverage measurement.

One more thing: in the Clover report you can define your own code metrics; they could include LOC/NCLOC information. See:

Hi Marek,

Thanks for quick reply.

Can you please let me know "Branch, stmt, Method and Total are caluclated against LOC or NCLOC?

Thanks,

Ranga
