II. The Patterns > 12. Utility Patterns
12. Utility Patterns
The utility patterns aid modular development. Unlike the other patterns, they don’t emphasize reuse, extensibility, or usability. Instead, the utility patterns support the other patterns and discuss ways that modularity can be enforced and help address quality-related issues. The utility patterns include the following:
• Colocate Exceptions: Exceptions should be close to the class or interface that throws them.
• Levelize Build: Execute the build in accordance with module levelization.
• Test Module: Each module should have a corresponding test module.
