Collecting Code Coverage

C/C++test CT supports the following code coverage metrics:

• Block Coverage (BC)
• Call Coverage (CC)
• Decision (Branch) Coverage (DC)
• Function Coverage (FC)
• Line Coverage (LC)
• Modified Condition Decision Coverage (MCDC)
• Simple Condition Coverage (SCC)
• Statement Coverage (SC)

Follow the procedure below to collect code coverage.

1. Instrument and build your code with the cpptestcc coverage tool; see Collecting Code Coverage for more details on cpptestcc.
   .map files will be created.
2. Execute the instrumented application.
   A .clog file will be created.
3. Generate coverage data files using cpptestcov compute:  
   

   cpptestcov compute -map=.cpptest/cpptestcc -clog=cpptest_results.clog -out=cov-data-run1

4. Report coverage statistics using cpptestcov report text.

   cpptestcov report text cov-data-run1

The basic workflow can be further extended with the following steps:

• Generate an HTML report using cpptestcov report html.
• Apply coverage suppressions using cpptestcov suppress.
• Report lines notcovered using cpptestcov report uncovered-lines.
• Merge multiple coverage data folders using cpptestcov merge.
• Publish coverage statistics to Parasoft DTP using cpptestcov report dtp.
• Report line coverage in lcov format using cpptestcov report lcov.
• Report line coverage in Cobertura format using cpptestcov report cobertura.
