printf: convert self-test to KUnit

2025-03-13T17:26:33+00:00

Convert the printf() self-test to a KUnit test. In the interest of keeping the patch reasonably-sized this doesn't refactor the tests into proper parameterized tests - it's all one big test case.

selftests: Warn about skipped tests in result summary

2025-01-15T00:06:31+00:00

Update the functions that print the test totals at the end of a selftest to include a warning message when skipped tests are detected. The message advises users that skipped tests may indicate missing configuration options and suggests enabling them to improve coverage.

selftests/net: packetdrill: report benign debug flakes as xfail

2025-01-07T10:23:37+00:00

A few recently added packetdrill tests that are known time sensitive (e.g., because testing timestamping) occasionally fail in debug mode: https://netdev.bots.linux.dev/contest.html?executor=vmksft-packetdrill-dbg These failures are well understood. Correctness of the tests is verified in non-debug mode. Continue running in debug mode also, to keep coverage with debug instrumentation. But, only in debug mode, mark these tests with well understood timing issues as XFAIL (known failing) rather than FAIL when failing. Introduce an allow list xfail_list with known cases. Expand the ktap infrastructure with XFAIL support.

selftests: ktap_helpers: Fix uninitialized variable

2024-12-19T01:00:29+00:00

__ktap_test() may be called without the optional third argument which is an issue for scripts using `set -u` to detect uninitialized variables and potential bugs. Fix this optional "directive" argument by either using the third argument or an empty string. This is required for the next commit to properly test script execution control.

selftests: support interpreted scripts with ksft_runner.sh

2024-09-10T00:38:02+00:00

Support testcases that are themselves not executable, but need an interpreter to run them. If a test file is not executable, but an executable file ksft_runner.sh exists in the TARGET dir, kselftest will run ./ksft_runner.sh ./$BASENAME_TEST Packetdrill may add hundreds of packetdrill scripts for testing. These scripts must be passed to the packetdrill process. Have kselftest run each test directly, as it already solves common runner requirements like parallel execution and isolation (netns). A previous RFC added a wrapper in between, which would have to reimplement such functionality.

selftests: ksft: Fix finished() helper exit code on skipped tests

2024-07-31T17:38:56+00:00

The Python finished() helper currently exits with KSFT_FAIL when there are only passed and skipped tests. Fix the logic to exit with KSFT_PASS instead, making it consistent with its C and bash counterparts (ksft_finished() and ktap_finished() respectively). Reviewed-by: Nícolas F. R. A.

selftests: ktap_helpers: Make it POSIX-compliant

2024-05-06T19:57:20+00:00

There are a couple uses of bash specific syntax in the script. Change them to the equivalent POSIX syntax. This doesn't change functionality and allows non-bash test scripts to make use of these helpers.
