4 KUnit Architecture
7 The KUnit architecture is divided into two parts:
15 The kernel testing library supports KUnit tests written in C using
16 KUnit. These KUnit tests are kernel code. KUnit performs the following
26 The test case is the fundamental unit in KUnit. KUnit test cases are organised
27 into suites. A KUnit test case is a function with type signature
28 ``void (*)(struct kunit *test)``. These test case functions are wrapped in a
34 Each KUnit test case receives a ``struct kunit`` context object that tracks a
35 running test. The KUnit assertion macros and other KUnit utilities use the
36 ``struct kunit`` context object. As an exception, there are two fields:
47 A KUnit suite includes a collection of test cases. The KUnit suites

162 You have two options for running KUnit tests: either build the kernel with KUnit
