Re: [PATCH v3 3/3] kunit: Add example of test suite that can be skipped at runtime

[David Gow]

> Add an example test suite name 'example_test_skip_suite' to
> 'kunit-example-test.c' that shows how to skip an entire test suite based on
> runtime conditions.
> 
> The example suite 'example_skip_suite' provides a 'suite_init' callback
> named example_skip_suite_init() which marks the entire suite as skipped
> using kunit_mark_skipped().
> 
> This demonstrates a way for conditionally skipping test suites when any
> prerequisites for kunit_suite execution are not met. The 'suite_init'
> callback can perform any necessary checks and mark the suite as skipped,
> preventing all test cases from executing while also indicating why the
> suite was skipped.
