Summary of Changes

Hello @bootjp, 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 improves the robustness of a Redis test by introducing an eventual consistency check for key deletion. By adding a timeout to the assertion, the test now gracefully handles potential delays in Redis's key removal process, thereby preventing intermittent test failures and ensuring more reliable test results.

Highlights

• Test Reliability: The TestRedis_follower_redirect_node_set_get_deleted test has been updated to use assert.Eventually when checking for Redis key deletion. This change introduces a timeout, allowing the test to wait for up to 2 seconds for the key to be confirmed as deleted, accounting for potential eventual consistency or latency in Redis operations.

Code Review

This pull request improves the robustness of a test by introducing assert.Eventually to handle potential replication delays when checking for key deletion on a follower node. This is a good change that should prevent test flakiness. I've added one suggestion to further improve the code's maintainability by replacing magic numbers with named constants.

[gemini-code-assist]

Using assert.Eventually is a great way to handle potential replication delays in this test. To improve readability and maintainability, consider extracting the magic numbers for the timeout (2*time.Second) and tick interval (50*time.Millisecond) into named constants.

This makes their purpose clearer and simplifies future modifications. You could define them at the top of the test function, for example:

const (
    replicationTimeout = 2 * time.Second
    checkInterval      = 50 * time.Millisecond
)

Then, you can use these constants in the assert.Eventually call.
