wibble-test-genrunner

wibble-test-genrunner(1)				      General Commands Manual					  wibble-test-genrunner(1)

NAME

       wibble-test-genrunner - Code generator for wibble testsuites.

SYNOPSIS

       wibble-test-genrunner header <file>

       wibble-test-genrunner main <files>

DESCRIPTION

       The  program  generates	.cpp files that are then compiled and linked into a test program for running tests from .test.h files. Examples of
       such .test.h files may be found among wibble headers, eg. /usr/include/wibble/regexp.test.h.

       In the first form, the program processes a single header file (usually of the form foo.test.h) and produces a corresponding .cpp file to be
       compiled. In the second form, it takes as <files> all the .test.h headers and produces a single main.cpp which contains the main() function
       of the test program, which then runs all the tests in all the .test.h files. The generated source code is always written to standard output
       and it is left up to the user to redirect it to a meaningful location.

       The program currently has no options other than the two forms above. The program is intended to be run as part of build process of programs
       or libraries using the wibble testing framework. For convenient use from CMake, there is a test.cmake script under /usr/share/wibble,  that
       takes  care  of producing all the .cpp files (both per-header and the main one), compiling them and linking them into a single binary which
       executes the testsuite.
