Line range hint 77-135: Review the modifications in the PushPull function.

The addition of the cpTest boolean parameter is used to control the flow of execution for testing purposes. When cpTest is true, the function returns ErrCheckpointTest, which simulates a failure scenario for consistency checks.

Considerations:

  • Ensure that this new testing pathway does not interfere with the normal operation of the PushPull function.
  • Verify that all existing calls to PushPull have been appropriately updated to include the new parameter, to avoid breaking changes.
Verification successful

All PushPull function calls have been updated to include the cpTest parameter. The verification confirms that the new testing pathway does not interfere with the normal operation of the PushPull function, and all existing calls have been appropriately updated to include the new parameter.

server/packs/packs_test.go (1)

127-231: Approve the new test implementations in server/packs/packs_test.go.

The tests are well-structured and effectively simulate different scenarios to test the new cpTest parameter in the PushPull function. These tests ensure that the function behaves as expected under both normal and simulated failure conditions.

test/bench/push_pull_bench_test.go (1)

Line range hint 150-272: Approve the modifications in benchmark tests.

The updates to include the cpTest parameter with a value of false in the PushPull function calls are correctly implemented. These changes ensure that the benchmark tests reflect the performance of the function under normal conditions, which is crucial for accurate performance evaluation.

server/rpc/yorkie_server.go (4)

167-167: Verify the impact of the new boolean parameter in PushPull.

The addition of the false parameter to the PushPull function call in AttachDocument method is consistent with the PR's objective to introduce a consistency test. However, it's crucial to verify that this change aligns with the expected behavior of the PushPull function and does not introduce any unintended side effects.

Verification successful

The addition of the boolean parameter in PushPull is consistent and intentional.

The boolean parameter added to the PushPull function call in the AttachDocument method is part of the PushPullOptions struct. It is consistently used across the codebase, including in test files and the yorkie_server.go file, aligning with the PR's objectives. There are no indications of unintended side effects.

  • The PushPull function calls in yorkie_server.go and other files confirm the consistent use of the boolean parameter.

Add a comment for the exported variable ErrCheckpointTest.

The static analysis tool has flagged this line because exported variables in Go should have a comment describing their purpose. This is a best practice to maintain code readability and documentation.

Suggest adding a comment above the variable declaration:

// ErrCheckpointTest is an error used to simulate a failure for checkpoint testing purposes.

I applied mocking to the test code and marked the test as skipped as a TODO.
Can you please review the changes?

17-338: Comprehensive Review of Mock Database Implementation

The new file mock_db.go introduces a mock database implementation which is crucial for testing the functionality of the Yorkie project without interacting with the actual database. The use of mock.Mock from the testify library is appropriate and aligns with common practices in Go for creating test doubles.

Each method properly delegates to the real database's corresponding method, which is a good practice ensuring that the mock behaves similarly to the actual database under test conditions. This approach helps in maintaining consistency in test environments and can significantly aid in the detection of issues during the development phase.

Overall, the implementation is clean, follows Go's idiomatic practices, and should serve its intended purpose effectively.

The test code looks to be well written!

However, there seems to be some problems with the current MockDB as follows:

  1. When there is a change in the Database interface, MockDB does not satisfy the Database interface, which is easily broken.
  2. Although it is MockDB, the remaining methods are not stubbable except for the UpdateClientInfoAfterPushPull method.

To properly address this, I've been considering two solutions as follows:

  1. Embed the Database interface inside the MockDB struct, inject the MongoDB implementation externally, and override only the methods that require stubbing. In this case, I think we can stub only the necessary methods while minimising the boilerplate code.
  2. Use Mockery to automatically generate mocks for the Database interface, and put the actual DB logic needed by the test inside the stubbing logic. In this case, I think partial mocking would be possible.

In my opinion, option 1 would be a good way to improve the problem, because it doesn't rely on external libraries and minimises boilerplate code.

The test case simulates a partial failure in PushPull logic, exposing the
current limitation in change validation. By implementing this test, we aim
to improve the robustness of our system against duplicate changes and
maintain data consistency across partial failures.

To ensure idempotency of duplicate operations and prevent unintended
consequences, we need to implement additional validation beyond ClientSeq.
