This approach requires the creation of a test case using the KUNIT_CASE_PARAM() macro that accepts a generator function as input. This generator function should return the next parameter given the previous parameter in parameterized tests. It also provides a macro to generate common-case generators based on arrays. Generators may also optionally provide a human-readable description of parameters, which is displayed where available. Note, currently the result of each parameter run is displayed in diagnostic lines, and only the overall test case output summarizes TAP-compliant success or failure of all parameter runs. In future, when supported by kunit-tool, these can be turned into subsubtest outputs. Signed-off-by: Arpitha Raghunandan <98.arpi@gmail.com> Co-developed-by: Marco Elver Signed-off-by: Marco Elver --- Changes v6->v7: - Clarify commit message. - Introduce ability to optionally generate descriptions for parameters; if no description is provided, we'll still print 'param-N'. - Change diagnostic line format to: # : N - [] Changes v5->v6: - Fix alignment to maintain consistency Changes v4->v5: - Update kernel-doc comments. - Use const void* for generator return and prev value types. - Add kernel-doc comment for KUNIT_ARRAY_PARAM. - Rework parameterized test case execution strategy: each parameter is executed as if it was its own test case, with its own test initialization and cleanup (init and exit are called, etc.). However, we cannot add new test cases per TAP protocol once we have already started execution. Instead, log the result of each parameter run as a diagnostic comment. Changes v3->v4: - Rename kunit variables - Rename generator function helper macro - Add documentation for generator approach - Display test case name in case of failure along with param index Changes v2->v3: - Modifictaion of generator macro and method Changes v1->v2: - Use of a generator method to access test case parameters Changes v6->v7: - Clarify commit message. - Introduce ability to optionally generate descriptions for parameters; if no description is provided, we'll still print 'param-N'. - Change diagnostic line format to: # : N - [] - Before execution of parameterized test case, count number of parameters and display number of parameters. Currently also as a diagnostic line, but this may be used in future to generate a subsubtest plan. A requirement of this change is that generators must generate a deterministic number of parameters.
