ISTQB - International Software Testing Qualifications Board Testing Throughout the Lifecycle Questions and Answers

Question 1

In the context of a sequential software development lifecycle model, such as the V-model, when should test analysis and design for a specific test level ideally begin?

Accepted Answer

As soon as the development activities for the corresponding level are underway.

Answer

After the code for that level has been fully developed and passed to the test team.

Answer

During the execution phase of the previous test level.

Answer

Once the entire system has been built and is ready for system testing.

Question 2

A project team is developing a large, complex system with stringent safety requirements. The development model is highly structured, with distinct phases for requirements, high-level design, detailed design, and coding. Which testing level corresponds directly to the high-level design (architectural design) phase in a V-model?

Accepted Answer

System Testing

Answer

Acceptance Testing

Answer

Component Testing

Answer

Integration Testing

Question 3

Which of the following is a primary objective of Maintenance Testing?

Accepted Answer

To verify that modifications in an operational system have not introduced adverse side effects.

Answer

To test a new system from scratch before its initial deployment.

Answer

To verify that new functionality has been added as per the initial project plan.

Answer

To confirm that a new developer understands the existing system architecture.

Question 4

The 'shift left' approach to testing primarily aims to:

Accepted Answer

Initiate testing activities earlier in the software development lifecycle.

Answer

Move all testing activities to be the sole responsibility of the development team.

Answer

Focus exclusively on end-to-end testing after the system is fully integrated.

Answer

Delay testing until the final stages to have a more stable system to test.

Question 5

A team is developing a mobile application using an iterative lifecycle model. A new feature has been added in the latest iteration. In addition to testing the new feature itself, what other crucial testing activity must be performed?

Accepted Answer

Regression testing of existing application features.

Answer

Usability testing with a focus group of new users only.

Answer

Performance testing on the oldest supported device.

Answer

A full security audit of the entire codebase.

Question 6

In any software development lifecycle model, which of the following is considered a characteristic of good testing?

Accepted Answer

For every development activity, there is a corresponding testing activity.

Answer

Testers are only involved after the coding phase is complete to ensure their independence.

Answer

Test level objectives are kept generic to allow for flexibility across the project.

Answer

Test analysis and design are postponed until a stable build is available for execution.
