This PR proposes a set of small optimizations and cleanup procedure to run the netshaper tests smoother and faster

Please note that the system tests are filing due to a series of issues that are resolved in #535

Summary by CodeRabbit

  • New Features

    • Enhanced test management with systematic instance naming to improve clarity and reduce name collisions.
    • Introduced mechanisms for thread-safe test cleanup, optimizing resource management and execution flow.
  • Bug Fixes

    • Improved synchronization during test cleanup to ensure resources are released efficiently after all tests complete.

@mojtaba-esk mojtaba-esk added this to the v0.15.0 milestone Aug 23, 2024

Walkthrough

The changes introduce a namePrefix constant to enhance instance naming in test functions within the netshaper_test.go file, replacing hardcoded names to avoid collisions. Additionally, a mutex and atomic counter are added in suite_setup_test.go to manage test cleanup operations safely, replacing the previous teardown method with a new approach that invokes cleanup after each test, ensuring resources are released appropriately.

Changes

Files Change Summary
e2e/netshaper/netshaper_test.go Introduced namePrefix constant for dynamic instance naming to reduce collisions in tests.
e2e/netshaper/suite_setup_test.go Added cleanupMu mutex and totalTests atomic counter for thread-safe cleanup management; replaced TearDownSuite with TearDownTest to improve control flow.

🐇 "In the land of tests, where all things align,
A prefix for names, oh how they shine!
With mutexes twirling and counters in play,
Cleanup is tidy, all in a day.
Hop, skip, and jump through each test with glee,
Our code now dances, as happy as can be!" 🎉

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

e2e/netshaper/suite_setup_test.go (5)

18-20: Concurrency management improvements are appropriate.

The addition of cleanupMu and totalTests to the Suite struct is a good approach for managing concurrency in test execution and cleanup.


23-24: No changes made to TestRunSuite.

The function remains unchanged and requires no review comments.


39-42: Setup for parallel test execution is correctly implemented.

The SetupTest function appropriately increments the totalTests counter and allows tests to run in parallel.


45-55: Synchronization and cleanup logic is well-implemented.

The TearDownTest function effectively uses a mutex to manage synchronization and ensures cleanup occurs only after all tests are finished.


57-62: Cleanup actions and error handling are appropriate.

The cleanupSuite function correctly handles cleanup operations and logs errors, ensuring test environment integrity.

e2e/netshaper/netshaper_test.go (4)

24-42: Instance naming and cleanup logic are well-implemented.

The use of namePrefix for instance names enhances clarity and reduces collision risk. The cleanup function ensures proper resource release.


Line range hint 127-152: Consistent instance naming and cleanup strategy.

The use of namePrefix is consistent with other tests, and the absence of a separate cleanup function suggests reliance on suite-level cleanup.


Line range hint 220-245: Consistent instance naming and cleanup strategy.

The use of namePrefix is consistent with other tests, and the absence of a separate cleanup function suggests reliance on suite-level cleanup.


Line range hint 320-345: Consistent instance naming and cleanup strategy.

The use of namePrefix is consistent with other tests, and the absence of a separate cleanup function suggests reliance on suite-level cleanup.
