kconfig: tests: add framework for Kconfig unit testing Many parts in Kconfig are so cryptic and need refactoring. However, its complexity prevents us from moving forward. There are several naive corner cases where it is difficult to notice breakage. If those are covered by unit tests, we will be able to touch the code with more confidence. Here is a simple test framework based on pytest. The conftest.py provides a fixture useful to run commands such as 'oldaskconfig' etc. and to compare the resulted .config, stdout, stderr with expectations. How to add test cases? ---------------------- For each test case, you should create a subdirectory under scripts/kconfig/tests/ (so test cases are separated from each other). Every test case directory should contain the following files: - __init__.py: describes test functions - Kconfig: the top level Kconfig file for the test To do a useful job, test cases generally need additional data like input .config and information about expected results. How to run tests? ----------------- You need python3 and pytest. Then, run "make testconfig". O= option is supported. If V=1 is given, detailed logs captured during tests are displayed.
