Testing Marker Name Processing with Special Characters in lottie-android

This test suite examines the Marker class functionality in Lottie Android, focusing on marker name handling and validation. It specifically tests the marker name matching behavior with special characters like carriage returns, ensuring robust text processing in animation markers.

Test Coverage Overview

The test coverage focuses on the Marker class’s name matching capabilities in Lottie Android.

Key areas tested include:

Case-insensitive name matching
Special character handling (carriage returns)
Basic marker initialization with coordinates

The suite specifically verifies edge cases involving string normalization and whitespace handling.

Implementation Analysis

The testing approach utilizes JUnit’s assertion framework for validating marker name matching logic.

Implementation patterns include:

Direct instance creation testing
Boolean assertion verification
String normalization verification

The test leverages JUnit’s @Test annotation for test case organization.

Technical Details

Testing infrastructure includes:

JUnit 4 testing framework
Static assertion imports for clean test syntax
Marker class constructor testing
Float parameter handling for animation timing

Best Practices Demonstrated

The test suite exemplifies several testing best practices:

Single responsibility principle in test methods
Clear test method naming conventions
Explicit test case setup
Focused assertion statements
Proper handling of special characters in test data
