Study Notes
Implementation and Testing
Coding Standards
- Code should be easy to add to, maintain, and debug
- Neatly commented code with explanations of complicated constructs and the reasoning behind them
- A coding standards document establishes consistent coding practices across a project
- Importance of coding standards:
- Improves readability
- Simplifies copying, editing, and maintenance
- Enables company-wide standardization
Principles of Good Programming
- KISS (Keep It Short and Simple)
- DRY (Don't Repeat Yourself)
- Abstraction (each piece of functionality in a program should be implemented in one place)
- Open/Closed Principle (software entities should be open for extension but closed for modification)
Single Responsibility Principle
- A component of code should perform a single well-defined task
Minimize Coupling and Maximize Cohesion
- Minimize dependencies on other areas of code
- Code with similar functionality should be found within the same component
Naming Conventions
- No abbreviations
- Meaningful names that are descriptive but concise
Loop Indices
- Example of proper loop indexing
Code Smells
- Duplicated code
- Large classes
- Long methods
- Long parameter lists
Refactoring
- Improves software internal structure without changing or adding behavior
- Benefits:
- More readable code
- Simplified code
- Easier to change and add new value
- Reduced redundancy
- Advises on how to improve software
- Automatic tests
Testing
- Importance of testing: finding errors prior to delivery to the end user
- Types of testing:
- Unit testing: testing individual programs or modules
- Integration testing: testing two or more programs that depend on each other
- System testing: verifying all system components are integrated properly
- Test plan: a guide to test software using "dummy data"
- Example of a test plan
Summary
- Importance of testing
- Types of testing
- Test plan
