sysclt: Clarify the results of selftest run

2023-12-28T12:57:57+00:00

In some cases the result of test were hidden inside the stdout and it was difficult to identify when a test was skipped and why. List of changes 1. Capitalize all the words that express a test result : "OK", "SKIPPED" and "FAIL". 2. Place all test result text at the end of the message. This will prevent the result from being hidden when stdout is verbose. 3. Any other explanation that comes after the result text will be placed in a new line. 4. All failures are marked as "FAIL" 5. Pipped the failure to stderr in tests 8, 9, 10. 6. Replaced bogus "FAIL" with "SKIPPED" in test 0007 7. All "..." are prefixed and followed by a space.

sysctl: Add a selftest for handling empty dirs

2023-12-28T12:57:57+00:00

Basic test to ensure that empty directories can be registered and that they in turn can serve as a base dir for other registrations. Add one test to the sysctl selftest module. It first registers an empty directory under "empty_add" and then uses that as a base to register another empty dir. The sysctl bash script then checks that "empty_add" is present and that there an empty directory within it. Signed-off-by: Joel Granados Signed-off-by: Luis Chamberlain

test_sysclt: Test for registering a mount point

2023-06-18T09:32:54+00:00

Test that target gets created by register_sysctl_mount_point and that no additional target can be created "on top" of a permanently empty sysctl table. Create a mount point target (mnt) in the sysctl test driver; try to create another on top of that (mnt_error). Output an error if "mnt_error" is present when we run the sysctl selftests.

test_sysctl: Add an option to prevent test skip

2023-06-18T09:32:54+00:00

Tests were being skipped because the target was not present. Add a flag that controls whether to skip a test based on the presence of the target. Actually skip tests in the test_case function with a "return" instead of a "continue". Signed-off-by: Joel Granados Signed-off-by: Luis Chamberlain

test_sysctl: Add an unregister sysctl test

2023-06-18T09:32:54+00:00

Add a test that checks that the unregistered directory is removed from /proc/sys/debug Signed-off-by: Joel Granados Signed-off-by: Luis Chamberlain

test_sysctl: Fix test metadata getters

2023-06-18T09:32:53+00:00

The functions get_test_{count,enabled,target} use awk to get the N'th field in the ALL_TESTS variable. A variable with leading zeros (e.g. 0009) is misinterpreted as an entire line instead of the N'th field. Remove the leading zeros so this does not happen. We can now use the helper in tests 6, 7 and 8. Signed-off-by: Joel Granados Signed-off-by: Luis Chamberlain

testing: use the copyleft-next-0.3.1 SPDX tag

2022-11-08T14:44:02+00:00

Two selftests drivers exist under the copyleft-next license. These drivers were added prior to SPDX practice taking full swing in the kernel. Now that we have an SPDX tag for copyleft-next-0.3.1 documented, embrace it and remove the boiler plate.

lib/test_sysctl: support testing of sysctl. boot parameter

2020-06-08T18:05:56+00:00

Testing is done by a new parameter debug.test_sysctl.boot_int which defaults to 0 and it's expected that the tester passes a boot parameter that sets it to 1. The test checks if it's set to 1. To distinguish true failure from parameter not being set, the test checks /proc/cmdline for the expected parameter, and whether test_sysctl is built-in and not a module.
