Abstract: Code coverage detection for interpreted scriptable programming languages avoids source code modification. Each program element of the script is performed by (a) using a debugger to proactively computationally indicate in a coverage data structure that the element was reached, and integrally (b) running non-logger executable code which corresponds to the element. Coverage of lines, statements, and other program elements during script execution can be measured even though the source code has not been instrumented with injected log statements. Proactively generated breakpoints pass control from each coverage-tracked program element into a code coverage debugger which updates the coverage data structure. Comments are skipped. Code coverage detection may be invoked from a command line, an Integrated Development Environment, or another context. The coverage data structure is correlated with the source code to produce a coverage map that is displayed to users showing which source code was performed.
