Software Development Methodologies Quiz

Which of the following software development methodologies is most suitable for small-sized applications?

• Agile methodology

• Spiral methodology

• V-Model methodology

• Waterfall methodology

Answer explanation

Agile methodology is most suitable for small-sized applications due to its flexibility, iterative approach, and focus on customer feedback, allowing for quick adjustments and faster delivery compared to other methodologies.

Select another software development methodology that is suitable for small-sized applications.

• Waterfall methodology

• DevOps methodology

• Large-Scale Scrum (LeSS)

• Rational Unified Process (RUP)

Answer explanation

The Waterfall methodology is suitable for small-sized applications due to its linear and sequential approach, making it easier to manage and implement in projects with well-defined requirements and limited scope.

Which of the following best describes the Agile methodology?

• A sequential approach where each phase must be completed before the next begins

• An iterative and incremental approach that emphasises flexibility and customer collaboration

• A methodology focused solely on testing

• A process that only uses automated tools

Answer explanation

The Agile methodology is best described as an iterative and incremental approach that emphasizes flexibility and customer collaboration, allowing teams to adapt to changes and deliver value continuously.

What is the main characteristic of the Waterfall methodology?

• Iterative development with frequent feedback

• Simultaneous development and testing

• Sequential phases where each phase must be completed before the next starts

• Continuous integration and deployment

Answer explanation

The Waterfall methodology is characterized by sequential phases, where each phase must be completed before the next one starts. This linear approach contrasts with iterative methods that allow for feedback and simultaneous development.

Which of the following is a unit testing technique?

• Testing the interaction between multiple modules

• Testing individual components or functions in isolation

• Testing the entire system as a whole

• Testing by the end user before release

Answer explanation

The correct choice is 'Testing individual components or functions in isolation' as it specifically refers to unit testing, which focuses on verifying the smallest parts of the code independently from the rest.

What is the primary purpose of integration testing?

• To test individual units of code

• To verify that different modules or components work together correctly

• To check the system’s performance under load

• To validate the software against user requirements

Answer explanation

The primary purpose of integration testing is to verify that different modules or components work together correctly, ensuring that they interact as expected when combined.

Which debugging technique involves pausing program execution at a specific line to inspect variables and program flow?

• Print statement debugging

• Debugging with breakpoints

• Rubber duck debugging

• Code review

Answer explanation

Debugging with breakpoints allows you to pause program execution at specific lines, enabling you to inspect variables and the flow of the program. This technique is essential for identifying issues in code effectively.

Match the following software testing methodologies with their correct definitions: 1. Unit Testing 2. Integration Testing 3. System Testing 4. Acceptance Testing Which option correctly matches the definitions?

• 1: Testing modules together, 2: Testing by users, 3: Testing individual units, 4: Testing the whole system

• 1: Testing individual units, 2: Testing modules together, 3: Testing the whole system, 4: Testing by users

• 1: Testing the whole system, 2: Testing by users, 3: Testing modules together, 4: Testing individual units

• 1: Testing by users, 2: Testing the whole system, 3: Testing individual units, 4: Testing modules together

Answer explanation

The correct matches are: 1: Testing individual units, 2: Testing modules together, 3: Testing the whole system, 4: Testing by users. This aligns with standard definitions in software testing methodologies.

What is the general purpose of data structures in software development?

• To make code more colourful

• To organise and manage data efficiently

• To increase the size of the application

• To slow down program execution

Answer explanation

The general purpose of data structures is to organise and manage data efficiently, allowing for better performance and easier data manipulation in software development.

Which of the following is NOT a benefit of using breakpoints during debugging?

• Allows inspection of variable values at specific points

• Helps to step through code execution line by line

• Automatically fixes code errors

• Assists in identifying logical errors

Answer explanation

The correct choice is 'Automatically fixes code errors' because breakpoints help in inspecting variables, stepping through code, and identifying logical errors, but they do not fix errors automatically.
