This patch set proposes KUnit, a lightweight unit testing and mocking
framework for the Linux kernel.
## More information on KUnit
There is a bunch of documentation near the end of this patch set that
describes how to use KUnit and best practices for writing unit tests.
For convenience I am hosting the compiled docs here:
Additionally for convenience, I have applied these patches to a branch:
The repo may be cloned with:
git clone https://kunit.googlesource.com/linux
This patchset is on the kunit/rfc/5.0-rc5/v4 branch.
## Changes Since Last Version
- Got KUnit working on (hypothetically) all architectures (tested on
x86), as per Rob's (and other's) request
- Punting all KUnit features/patches depending on UML for now.
- Broke out UML specific support into arch/um/* as per "[RFC v3 01/19]
kunit: test: add KUnit test runner core", as requested by Luis.
- Added support to kunit_tool to allow it to build kernels in external
directories, as suggested by Kieran.
- Added a UML defconfig, and a config fragment for KUnit as suggested
by Kieran and Luis.
- Cleaned up, and reformatted a bunch of stuff.
Someone suggested I should send the next revision out as "PATCH"
instead of "RFC" since there seems to be general consensus about
everything at a high level, with a couple exceptions.
At this time I am planning on sending the next revision out as "[PATCH
v1 00/NN] kunit: introduce KUnit, the Linux kernel unit testing
framework". Initially I wasn't sure if the next revision should be
"[PATCH v1 ...]" or "[PATCH v5 ...]". Please let me know if you have
strong objection to the former.
In the next revision, I will be dropping the last two of three patches
for the DT unit tests as there doesn't seem to be enough features
currently available to justify the heavy refactoring I did; however, I
will still include the patch that just converts everything over to
KUnit without restructuring the test cases:
I should have the next revision out in a week or so.
