D. Test Analysis.

When comparing Static and Dynamic test techniques, which of the following statements is TRUE?

Given the following state transition diagram where SS is the start state:

Which of the following answers describes a test case that only uses valid transitions to exercise all states, using the minimum number of transitions?

A. SS-S3-SS-S1-S3-S2.

B. SS-S3-S2-S1.

Which of the following BEST describes a methodical approach to the Error Guessing test technique?

A. A tester dynamically designs and executes tests based on their knowledge, to learn more about the system and to create tests for the areas that may need more testing.

B. An experienced tester makes a list of potential defects and failures, based on experience and past defect data. Then designs and runs tests to generate these failures should the defects be present in the code.

C. A tester designs, implements and executes tests to cover test conditions found in checklists that are based on what is important for the user.

D. An inexperienced tester is asked to attempt to guess errors that may have been missed by experienced testers during formal test design.

B. b, d and e.

C. a, b and e.

D. b, c and d.

An issue has been found in a production system, where a code component fails to release memory after it has finished using it. Which of the following tools would have been the MOST effective at detecting this defect during Performance testing?

A. Dynamic analysis tool.

B. Test Execution tool.

C. Configuration management tool.

D. Coverage measurement tool.

You have been asked to improve the way test automation tools are being used in your company. Which one of the following is the BEST approach?

A. Selecting and automating scripts that test new functionality to find the most defects.

B. Using a keyword-driven testing approach to separate the actions and data from the tool's script.

C. Ensuring that all data, inputs and actions are stored in the tool's script for ease of maintenance.

D. Keeping expected results separate from the automation tool to allow the testers to check the results.
