Which one of the following is the BEST definition of an incremental development model?

• Defining requirements, designing software and testing are done in phases where in each phase a piece of the system is added
• A phase in the development process should begin when the previous phase is complete
• Testing is viewed as a separate phase which takes place after development has been completed
• Testing is added to development as an increment

Given the following statements about the relationships between software development activities and test activities in the software development lifecycle: 1. Each development activity should have a corresponding testing activity 2. Reviewing should start as soon as final versions of documents become available 3. The design and implementation of tests should start during the corresponding development activity 4. Testing activities should start in the early stages of the software development lifecycle Which of the following CORRECTLY shows which are true and false?

• True – 1, 2; False – 3, 4
• True – 2, 3; False – 1, 4
• True – 1, 2, 4; False – 3
• True – 1, 4; False – 2, 3

Which of the following is a true statement regarding the V-model lifecycle?

• Testing involvement starts when the code is complete
• The test process is integrated with the development process
• The software is built in increments and each increment has activities for requirements, design, build and test
• All activities for development and test are completed sequentially

In an iterative lifecycle model, which of the following is an accurate statement about testing activities?

• For every testing activity, appropriate documentation should be produced, versioned and stored
• For every development activity, there should be a corresponding testing activity
• For every development activity resulting in code, there should be a testing activity to document test cases
• For every testing activity, metrics should be recorded and posted to a metrics dashboard for all stakeholders

Which of following statements is FALSE?

• IoT systems typically apply separate software development lifecycle models for each object
• Test levels and/or test activities are context independent
• An appropriate software development life cycle model should be based on identified product and project risks
• Software development models must be adapted to the expected product characteristics

Software development models must be adapted to____

• Testing model
• User requirements
• Testing process
• Context of the project

Component testing is also known as what?

• System Testing
• Integration Testing
• Unit Testing
• Acceptance Testing

What is the primary use of stubs and drivers in Component Testing?

• To test the performance of the entire system.
• To generate test data for functional testing.
• To replace missing software and simulate the interface between software components.
• To record defects in the user interface.
