Unit Testing Pattern

Effective unit tests for utility functions, validation logic, business rules, and error handling with comprehensive edge case coverage.

What's Included#

• Pure function testing with descriptive test names and grouped describe blocks
• Validation function testing with parameterized test cases using it.each
• Business logic testing for pricing calculations, discounts, and tax
• Error handling tests for API clients, parsing, and error extraction
• Test data fixtures for consistent, reusable test objects

Usage#

Via CLI#

Via AI Assistant#

Ask your AI assistant:

• "Use the unit testing pattern from Bootspring"
• "Apply the Bootspring unit testing pattern to my project"

Key Considerations#

• Test one behavior per test case for clear failure diagnosis
• Use the Arrange-Act-Assert structure for consistent test organization
• Cover edge cases including empty arrays, null values, and boundary conditions
• Use it.each for parameterized tests with multiple input/output combinations
• Keep tests independent so they can run in any order without side effects
