CL-Implemented Unit Tests For DeepLinkHelper Functionality

[melihalkbk]

📋 PR Description

📌 Description

This PR enhances the DeepLinkHelper class by improving its testability and error logging. The changes introduce unit tests for deep link handling while making logs more structured and visible with emoji-based error messages.

✅ Added Unit Tests

🔵 Valid Deep Link Test

• Ensures that a valid deep link successfully opens the target application.
• Mocks UIApplication behavior to verify that openURL is actually called.
• Passes when the application successfully processes the deep link.

🔴 App Not Installed Test

• Simulates a scenario where the target application is not installed.
• Ensures DeepLinkHelper logs an appropriate error message (🚫 "The required application is not installed on this device.").
• Passes when the correct error log is captured.

⚠️ Failed to Open Application Test

• Simulates an app launch failure even if canOpenURL returns true.
• Ensures that a failure log is recorded (⚠️ "Failed to open the application.").
• Passes when the expected error message is logged.

🎯 Improvements & Goals

These improvements ensure that:

• The DeepLinkHelper class is now fully testable with mock dependencies.
• Error logging is more structured and easily visible in console outputs.
• The deep link handling mechanism is robust and reliable under different conditions.

✅ Checklist

• Code follows the project standards and guidelines.
• Relevant unit tests are written and all tests are passing.
• Test coverage is adequate for the changes.
• Any unnecessary files or debug statements have been removed.
• Documentation is updated where necessary.
• The PR has been reviewed by at least one team member before merging.
