Correct Answer: C
Question No.274
When an organization considers the use of testing tools, they should:
-
Use a tool in order to help define a good test process because the tool will force process repeatability and therefore enforce good test process.
-
Always start by bringing in automated test execution tools as these tools have the greatest return on investment and therefore should be introduced first.
-
Perform analysis of the test process and then assess whether it can be supported through the introduction of tool support.
-
Allow the developers to select the testing tools because tools are technical and developers have the appropriate skills to advise on test tool selection and configuration.
Correct Answer: C
