Dusage.rst6 Test Cases
9 The fundamental unit in KUnit is the test case. A test case is a function with

19 void example_test_failure(struct kunit *test)
21 KUNIT_FAIL(test, "This test never passes.");
27 which is a special expectation that logs a message and causes the test case to
33 test. An expectation is called like a function. A test is made by setting
34 expectations about the behavior of a piece of code under test. When one or more
35 expectations fail, the test case fails and information about the failure is
