Caca Labs test suite

All our major projects feature an extensive test suite that checks the software for consistency, source code quality, features and regressions.

The testsuite can be run by typing make check in the project’s top directory.

Source code checks

Most source code checks rely on the project’s ability to list all source files. This is done by putting the following Makefile.am snippet in all directories that contain source code:

echo-sources: ; echo $(SOURCES)

... and the following snippet in the top directory Makefile.am:

echo-dirs: ; echo caca kernel src cxx examples ruby tools

check-source performs a source code quality check. It checks for the following coding style errors:

• no source code file should contains tabs
• no source code file should contain trailing spaces

check-copyright performs a copyright statement check. The following tests are performed:

• all source code files must contain a “Copyright (c)” statement
• all source code files must mention the year of the last modification (this check is only performed when in a git-svn repository)

check-win32 performs a Win32 port consistency check. The following tests are performed:

• all preprocessor tokens in config.h.in must appear in msvc/config.h
