- What is CoverageMeter ? -
CoverageMeter is a complete code coverage tool chain. It analyzes the performance of a software validation and permits to optimizes the testing process of a C/C++ applications:
* Finding untested code sections.
* Reducing the amount of tests by finding redundant tests.
* Finding unused source code. (dead code)
- How does it works? -
CoverageMeter is a test coverage analyzer for C/C++ programs. It is composed of 2 tools:
1. CoverageScanner , which analyzes, instruments and generates the C/C++ application.
2. CoverageBrowser , which displays and manages the results of the coverage analysis.
CoverageMeter instrumenst your source code during the compilation and generates an instrumented program. The instrumented program keeps track of the code instructions that were executed while the program was running and produces an execution report (csexe file) upon program termination.
CoverageScanner is a command line tool which substitutes the compiler. Principally, it inserts instrumentation instructions into the preprocessed source code and calls up the native compiler. (GCC, Borland ® C, Microsoft Visual ® C compiler,...) A database (.csmes file), which contains the list of instrumentations and a copy of the instrumented source code, is generated at the same time. CoverageScanner is configurable via a profile and can be adapted to most compilers present on the market.
After the generation, the program can be run as usual and produces an execution report on exit. (.csexe file) The execution report can be analyzed and managed using CoverageBrowser .
CoverageBrowser is a graphical interface which enables the user to browse and manage the execution reports. It therefoe enables the user to find untested code portions, dead code and inefficient tests.
