Description

Type of Change

• Bugfix
• Feature
• Code style update (formatting, local variables)
• Refactoring (no functional changes, no api changes)
• Tests
• Other

Motivation and Context

Several modules and components lacked unit test coverage, making it harder to catch regressions. This PR adds test suites for the areas with the most missing coverage and removes leftover console.log statements from VTEXIOMinicartBridge that were left over from debugging.

Summary of Changes

• MessagesList — Extended and added unit tests covering message rendering, scroll behavior, and edge cases.
• VTEXIOMinicartBridge — Added unit tests for cart merging, image preservation, and updateVTEXIOMinicart flow. Removed debug console.log calls that leaked internal state messages to the browser console.
• OrderFormContext — Added unit tests for context state, order form lifecycle, and cart sync logic.
• Dropdown — Added unit tests covering open/close behavior, placement classes, renderTrigger, outside-click dismissal, Escape key handling, and ARIA attributes.
• Tooltip — Added unit tests covering hover/focus visibility, disabled prop, preserved child event handlers, and aria-describedby linking.
• useVtexCxVisualViewportCssVars — Added unit tests for syncVtexCxVisualViewportCssVars (both visualViewport and fallback paths), listener registration, cleanup on unmount, and active toggling.
• CounterControls — Added unit tests covering counter increment/decrement, hideWhenNotInteracted visibility logic, uuid parsing, add-to-cart FSButton rendering, and async cart addition flow.
