Here is a minimal dummy example of a KTF unit test suite that defines
two tests, hello_ok and hello_fail. The test is in the examples
directory and is built with KTF:
.. literalinclude:: ../examples/hello.c :language: c
To run the test, cd to your KTF build tree and insmod the ktf module and the module that provides the test:
insmod kernel/ktf.ko insmod examples/hello.ko
Now you should be able to run one or more of the tests by running the
application ktfrun built in user/ktfrun. You should be able to run
that application as an ordinary user:
ktfrun --gtest_list_tests ktfrun --gtest_filter='*fail' ktfrun --gtest_filter='*ok'
There are more examples in the examples directory. KTF also includes a
selftest directory used to test/check the KTF implementation itself.
