Hi @KishibeKafka. Thanks for your PR.

I'm waiting for a fluid-cloudnative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Code Review

This pull request adds documentation comments to the TestAlluxioFileUtils_Count function in pkg/ddc/alluxio/operations/base_test.go. The reviewer noted that the comment for the NEGATIVE_RES test case is misleading because the test implementation provides malformed output, failing to actually exercise the negative value handling logic.

//
// Test cases:
// - EXEC_ERR: Tests handling of command execution errors.
// - NEGATIVE_RES: Tests handling of negative result values.

This comment states that the NEGATIVE_RES case tests handling of negative result values. However, the corresponding mock implementation for this test case returns a single line of output:

return "12324\t45463\t-9223372036854775808", "", nil

The Count function expects two lines of output (a header and a data line) and will fail on parsing if only one is provided. Therefore, this test case currently verifies handling of malformed output (incorrect number of lines), not the logic for handling negative values within the data itself.

To align the test with the comment, the mock should be updated to return two lines, ensuring the negative value check in the Count function is actually reached. For example:

return "File Count\tFolder Count\tTotal Bytes\n12324\t45463\t-9223372036854775808", "", nil

Since modifying the test logic is outside the scope of this PR, please consider either updating this comment to accurately describe the current test's behavior or addressing the test implementation in a separate PR.
