💡 Description

This PR refactors the HomepageTelemetry class to inject a custom GleanWrapper for better dependency management and to facilitate mocking in unit tests. The current approach directly interacts with Glean metrics, making it difficult to test and mock. By introducing a GleanWrapperProtocol and a CustomGleanWrapper class, we decouple the telemetry logic from Glean, allowing for more flexible and testable code. 🔧

Key Changes:

• GleanWrapperProtocol: Defines a protocol for interacting with Glean's telemetry methods. 📜
• CustomGleanWrapper: Implements the protocol, acting as the bridge to Glean's API for telemetry recording. 🧰
• HomepageTelemetry: Updated to inject the GleanWrapperProtocol, making it more modular and easier to mock for unit tests. 🔄

Additionally, I have added unit tests to verify the correct functionality of the sendHomepageTappedTelemetry method, ensuring that the proper telemetry data is being recorded based on the input values. These tests check both private and normal mode toggle scenarios. 🧪

Output Log:

• testPrivateModeShortcutToggleTappedInNormalMode:

  Test Passed: Metric recorded with isPrivateMode: true ✅
  

• testPrivateModeShortcutToggleTappedInPrivateMode:

  Test Passed: Metric recorded with isPrivateMode: false ✅
  

Test Cases:

• testPrivateModeShortcutToggleTappedInNormalMode: Verifies that the telemetry records "true" for the isPrivateMode flag when entering normal mode. 🔒
• testPrivateModeShortcutToggleTappedInPrivateMode: Verifies that the telemetry records "false" for the isPrivateMode flag when entering private mode. 🕵️

Issue:

• fixes: Use Glean Wrapper for HomepageTelemetry #24074

Thanks for the change! HomepageTelemetry looks great. We just miss to adjust the unit tests HomepageTelemetryTests and all should be good 👍
