Unit Testing Guidelines

General Principles

1. Test Independence

• Each test must be independent and self-contained
• Tests must not rely on execution order
• Use local variables within test methods instead of shared instance variables when possible

2. Clear Test Names

Follow the pattern: methodName_scenario_expectedBehavior

Examples: tableExists_positive_tableIsPresent, deleteTimer_negative_timerDescriptorIdIsNull

3. Test Organization

Structure every test with: Arrange → Act → Assert
