tests.
This ensures that we get information from all files, not just files that
had functions that were run.
This brings down the total number of covered functions significantly:
| Line Coverage | Functions |
--------+--------------------+------------------+
Before: | 43.0% (3308/7699) | 48.8% (266/545) |
After: | 15.2% (3308/21821) | 15.1% (266/1762) |
Excluded generated Qt and D-Bus files from the tests. Also exlcuded
pngcheck, since it's mostly third-party code.
TODO: Create some truncated ROM images to use as test cases and run them
in rpcli, and also compare extracted images.
Set ENABLE_COVERAGE=ON to enable code coverage testing.
After the build is finished, run 'make coverage' to run the unit tests
and generate a code coverage page in the ${CMAKE_BINARY_DIR}/coverage
directory.

CMakeLists.txt:
- Moved the CMAKE_BUILD_TYPE check to before INCLUDE(CTest),
and capitalized the 'D' in "Debug", since CodeCoverage.cmake
checks for that.
gcc.cmake:
- Set the required CFLAGS. (These aren't checked for explicitly, since
they're basically present on all gcc since forever.)
- Link all targets to -lgcov.
- Create a 'coverage' target for automatically running tests and
generating HTML output using lcov/genhtml.
options.cmake:
- Added ENABLE_COVERAGE.
scripts/lcov.sh:
- Shell script used by the 'coverage' target to generate the lcov/genhtml
output from the gcov profiling data.
