Which of the following statements are true?
(i) For every development activity there is a corresponding testing activity.
(ii) Each test level has the same test objectives.
(iii) The analysis and design of tests for a given test level should begin after the corresponding development activity.
(iv)Testers should be involved in reviewing documents as soon as drafts are available in the development life cycle.
For every development activity, there is a corresponding testing activity to ensure that testing is integrated into the development process. Additionally, involving testers early in the document review process allows for the identification of defects and issues early in the lifecycle, which aligns with the principles of early and continuous testing.
