Edge Case Tests

Identify and write tests for boundary conditions and unusual input scenarios.

Test Creation Checklist

Boundary Conditions

• Test minimum and maximum allowed values (0, 1, MAX_INT, etc.)
• Verify off-by-one behavior at array/collection boundaries
• Check date/time edge cases (leap years, timezone transitions, epoch)
• Test string length limits (empty, single char, maximum length)
• Validate range boundaries for numeric parameters

Null & Empty Handling

• Test null inputs for all nullable parameters
• Verify behavior with empty strings, collections, and maps
• Check optional/missing fields in structured data
• Test default value fallback when inputs are absent
• Validate graceful handling of uninitialized state
