This set of patches adds a simple unit-testing framework to Busybox unit-tests: add some helper macros for unit-test framework implementation unit-tests: implement the unit-testing framework unit-tests: add basic documentation on writing the unit test cases unit-tests: modify the Makefile 'test' target to run unit-tests too unit-tests: add two example test cases unit-tests: modify the existing strrstr test code to use the unit-test framework Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
