Summary of Changes

Hello @Abacn, 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 aims to improve the organization and maintainability of the Apache Beam Java SDK's test suite. It achieves this by refactoring the ViewTest class, moving all tests pertaining to View.asMap() and View.asMultimap() functionalities into a newly created, specialized test file, MapViewTest.java. This change ensures that map-related view tests are consolidated, simplifying future test development and debugging.

Highlights

• Test Refactoring: Extracted all tests related to View.asMap() and View.asMultimap() from ViewTest.java into a new, dedicated test file, MapViewTest.java.
• New Test File: Introduced MapViewTest.java to house comprehensive tests for map and multimap side inputs, covering various scenarios like basic usage, entry set access, in-memory views, non-deterministic key coders, windowed inputs, empty views, immutability, and combined inputs.
• Improved Organization: Enhanced the structure of the test suite by separating concerns, making it easier to locate and manage tests for specific View functionalities.

It seems beam_PreCommit_Java_PVR_Prism_Loopback is flaky (also flaky on master branch): https://github.com/apache/beam/actions/runs/18888383530/job/53909609623 cc: @shunping

I checked a few failed instances, but I could not see a pattern. It may be caused by the heavy load in the test machines. Will keep an eye on them.
