Summary

This PR introduces unit tests for the groupChatItemsByDeleteStatus utility function in the ChatContainer component. The tests cover various scenarios to ensure the function correctly groups chat items based on their delete status.

Key Changes:

1. Test Cases Added:

   • Empty input returns an empty array.

   • All normal items are grouped together.

   • All deleted items are grouped together.

   • Alternating normal and deleted items are grouped correctly.

   • Single normal item is handled correctly.

   • Single deleted item is handled correctly.

   • Interleaved normal and deleted items are grouped correctly.

   • Items with deleteTime=0 are treated as normal.

   • Items with deleteTime=null or undefined are treated as normal.

2. Test Coverage:

   • Ensures the function handles edge cases like empty arrays, single items, and interleaved items.

   • Validates the behavior for different deleteTime values, including 0, null, and undefined.

These tests ensure the robustness and reliability of the groupChatItemsByDeleteStatus function in handling various input scenarios.
