How are the Clover coverage percentages calculated?

The "total" coverage percentage of a class (or file, package, project) is provided as a quick guide to how well the class is covered - and to allow ranking of classes. The Total Percentage Coverage (TPC) is calculated using the formula:

 TPC = (CT + CF + SC + MC)/(2*C + S + M)

 where

 CT - conditionals that evaluated to "true" at least once

 CF - conditionals that evaluated to "false" at least once

 SC - statements covered

 MC - methods entered

 C - total number of conditionals

 S - total number of statements

 M - total number of methods
