Summary of Changes

Hello @havetisyan, 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 maintainability and readability of the InstanceAzureProviderTest suite by consolidating redundant test setup and teardown code. It extracts the logic for configuring system properties and managing temporary files into reusable helper methods, ensuring a consistent and clean testing environment across multiple test cases. This addresses issue #3169 by streamlining the test infrastructure.

Highlights

• Test Code Refactoring: The pull request refactors repetitive setup and teardown logic in InstanceAzureProviderTest.java into dedicated helper methods.
• New Helper Methods: Two new private methods, setupProviderSettings and clearProviderSettings, were introduced to encapsulate the configuration and cleanup of system properties and temporary files for Azure provider tests.
• Improved Test Readability: By abstracting common setup and teardown steps, individual test methods are now cleaner, more concise, and easier to understand.

Code Review

This pull request does a good job of refactoring duplicated test setup and teardown logic into helper methods, which improves the overall maintainability of the test suite. You've also corrected several tests by ensuring they have the proper setup.

While the goal was to update all test cases, it appears a few were missed, such as testConfirmInstance, testConfirmInstanceProviderConfig, and testConfirmInstanceAudienceMismatch. It would be great to include them in this refactoring effort for consistency.

I've also left a comment on the new helper methods with suggestions to make them more flexible and reusable by parameterizing the hardcoded resource URI and extracting duplicated file paths into constants.
