Summary of Changes

Hello @a-maurice, 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 code readability and maintainability of the automated test file for Firebase AI by applying consistent formatting rules. The changes are purely stylistic, ensuring that all code blocks, including if statements, loops, and method declarations, use explicit curly braces, without introducing any functional modifications to the tests themselves.

Highlights

• Code Formatting: The primary change involves applying consistent code formatting to the UIHandlerAutomated.cs file, ensuring uniform style across the test suite.
• Brace Style Consistency: Specifically, curly braces have been added to all single-line if, foreach, namespace, method, and class declarations to enforce a block style, enhancing readability.
• No Functional Changes: These changes are purely cosmetic and do not alter the functionality or behavior of the automated tests, as explicitly stated in the pull request description.

Code Review

This pull request focuses on formatting the automated test file UIHandlerAutomated.cs to use a consistent bracing style. The changes are purely stylistic as described.

My review confirms the formatting changes and also points out a few areas for improvement:

• An if statement was missed in the formatting pass, which I've flagged for consistency.
• Several hardcoded strings for model names and a magic number for float comparison could be extracted into constants to improve maintainability.
• The LoadStreamingAsset method can be simplified using async/await and a using block to improve readability and ensure proper resource disposal.

Overall, the formatting is a good step towards consistency. The additional suggestions aim to further improve the code's quality and maintainability.

The model name "gemini-2.0-flash-exp" is hardcoded. It would be better to define it as a constant at the top of the class, similar to TestModelName, to improve maintainability and avoid magic strings. For example: private readonly string TestGenerateImageModelName = "gemini-2.0-flash-exp";

      var model = GetFirebaseAI(backend).GetGenerativeModel(TestGenerateImageModelName,
