feat(consistent handling): Integration tests for creating symlinks with updated representation

[anushka567]

Description

This PR introduces a new suite of integration tests to validate the consistent handling of symbolic links in GCSFuse . It verifies that GCSFuse correctly creates and recognizes symlinks using both the updated (Standard) representation and the backward-compatible (Legacy) representation .

Context: go/sts-consistent-symlink-handling-in-gcsfuse

Link to the issue in case of a bug fix.

b/488952648

Testing details

1. Manual - Yes.
2. Unit tests - Added as part of feat(consistent symlink): changes for CreateSymlink flow for updated representation #4424
3. Integration tests - Automated. Link to successful run prior to rename only change - #15391

Any backward incompatible change? If so, please explain.

No.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the GCSFuse testing framework by adding a dedicated set of integration tests for symbolic link management. The primary goal is to ensure robust and consistent behavior when creating and interpreting symlinks, covering both modern 'Standard' and older 'Legacy' representations. This change improves the reliability of GCSFuse's symlink functionality by providing automated validation.

Highlights

• New Integration Tests for Symlink Handling: Introduced a new suite of integration tests to validate the consistent handling of symbolic links within GCSFuse.
• Standard and Legacy Symlink Validation: The tests specifically verify that GCSFuse correctly creates and recognizes symlinks using both the updated (Standard) representation and the backward-compatible (Legacy) representation.
• Test Configuration Updates: Updated the test runner script and configuration files to include and enable the execution of these new symlink handling tests.

Changelog

• tools/integration_tests/improved_run_e2e_tests.sh
  • Added 'symlink_handling' to the list of common test packages to be executed.
• tools/integration_tests/symlink_handling/create_symlink_test.go
  • Added a new Go test file containing BaseSymlinkSuite, StandardSymlinksTestSuite, and LegacySymlinksTestSuite to test the creation and validation of symlinks under different configurations.
• tools/integration_tests/symlink_handling/symlink_handling_test.go
  • Added a new Go test file that defines the test environment, constants for symlink metadata keys, and the TestMain function for setting up and running symlink handling integration tests.
• tools/integration_tests/test_config.yaml
  • Added a new 'symlink_handling' section to the YAML configuration, specifying test runs for both standard and legacy symlinks with their respective flags and compatibility settings.
• tools/integration_tests/util/test_suite/config.go
  • Extended the Config struct to include a SymlinkHandling field, allowing configuration of symlink-related tests.

Activity

• Manual testing was performed for these changes.
• Unit tests related to this feature were added in a separate pull request: feat(consistent symlink): changes for CreateSymlink flow for updated representation #4424.
• Automated integration tests have been introduced as part of this pull request.

Code Review

This pull request introduces integration tests for creating symbolic links, covering both standard and legacy representations. The changes are well-structured, adding a new symlink_handling test package and updating the necessary test configurations. The tests correctly validate the underlying GCS object representation for both symlink types. I've identified a couple of issues: one is a potential for silent failures in the test setup due to an unhandled error, and the other is a configuration mismatch that would prevent the new tests from running when using the test configuration file. I've provided suggestions to address these points.
