Final answer:
Testable code encourages loose coupling and encapsulation, which promotes modularity, reusability, and maintainability in software development. It also supports the use of short iterations, involving customer collaboration in the project. The correct option is B. Loose coupling and encapsulation
Step-by-step explanation:
Testable code encourages loose coupling and encapsulation in software code. Loose coupling refers to minimizing the dependencies between different components of the code, making them independent and easier to modify or replace. Encapsulation refers to encapsulating data and functions within an object, providing clear interfaces, and hiding the implementation details. This helps in achieving modularity, reusability, and maintainability in software development.
One example of loose coupling is using interfaces or abstract classes instead of concrete implementations, allowing different components to interact without directly depending on each other.
Another example of encapsulation is defining private variables and exposing them through public methods, ensuring controlled access to the data.
Additionally, testable code can also benefit from the use of short iterations (SI), which involves breaking down the development process into smaller, manageable increments. This allows customers to actively participate in the project, provide feedback, and adapt the software based on their needs.
The correct option is B. Loose coupling and encapsulation
