Abstract

Extend the code coverage instrumentation in Xdebug from statement coverage to include decision and path coverage. Xdebug will be able to report for a given block of code the number of unique branches, how many branches were executed during execution of the block, how many linearly independent paths exist through the code block, and which of these code paths were executed. A data structure representing which paths and branches were taken will be available to code coverage tools .
