12  * This is the most fundamental element of KUnit, the test case. A test case
14  * any expectations or assertions are not met, the test fails; otherwise, the
15  * test passes.
17  * In KUnit, a test case is just a function with the signature
19  * information about the current test.
21 static void example_simple_test(struct kunit *test)  in example_simple_test()  argument
25 	 * to test a piece of code, you set some expectations about what the  in example_simple_test()
26 	 * code should do. KUnit then runs the test and verifies that the code's  in example_simple_test()
29 	KUNIT_EXPECT_EQ(test, 1 + 1, 2);  in example_simple_test()
33  * This is run once before each test case, see the comment on

44  * Here we make a list of all the test cases we want to add to the test suite
49 	 * This is a helper to create a test case object from a test case
51 	 * use KUnit, just know that this is how you associate test cases with a
52 	 * test suite.
61  * Test cases are defined as belonging to the suite by adding them to
65  * will be used by every test; this is accomplished with an `init` function
66  * which runs before each test case is invoked. Similarly, an `exit` function
67  * may be specified which runs after every test case and can be used to for
68  * cleanup. For clarity, running tests in a test suite would behave as follows:
70  * suite.init(test);
71  * suite.test_case[0](test);
72  * suite.exit(test);
73  * suite.init(test);
74  * suite.test_case[1](test);
75  * suite.exit(test);
