Certified Associate in Software Testing (CAST) Practice Test

Which of the following testing types is concentrated on defect detection and removal after a work product is produced?

1. Validation

2. Verification

3. Static Testing

4. Dynamic Testing

The correct answer is: Validation

The appropriate choice for the focus on defect detection and removal after a work product is produced is dynamic testing. Dynamic testing involves executing the code and checking the behavior of the software under various conditions to identify any defects that may appear when the software is running. This type of testing can be performed at different levels, including unit testing, integration testing, system testing, and acceptance testing, all of which occur after the production of the software product. Validation, while important, primarily ensures that the software meets the business needs and requirements but may not specifically focus on detecting defects after production. Verification usually refers to evaluating products to ensure they meet specified requirements, which can occur early in the software development lifecycle. Static testing involves reviewing the documentation and code without executing the program and is not focused on defect detection in a running product. Therefore, the best option for this question is dynamic testing, as it specifically targets defect detection post-development.
