Pull Request Overview

This PR adds unit tests for the RadioButtonRenderer to improve code coverage for both public and internal methods and properties.

  • Introduces multiple test cases for rendering behaviors, state conversion, and background drawing.
  • Adds tests that validate behavior changes based on whether visual styles are enabled.
Comments suppressed due to low confidence (1)

src/test/unit/System.Windows.Forms/System/Windows/Forms/RadioButtonRendererTests.cs:1

  • The removal of '#nullable disable' suggests the file is now intended to support nullable reference types. Ensure that the rest of the file adheres to the project's nullability guidelines.
