Which of the following statements about estimation of the test effort is WRONG?

During component testing of a program if 100% decision coverage is achieved, which of the following coverage criteria is also guaranteed to be 100%?

Which of the following statements best describes how configuration management supports testing?

Determining the schedule for each testing activity and test milestones for a test project, using activity estimates, available resources, and other constraints is a typical task performed during

Following a risk-based testing approach you have designed 10 tests to cover a product risk with a high-risk level. You want to estimate, adopting the three-point test estimation technique, the test effort required to reduce the risk level to zero by executing those 10 tests. You made the following three initial estimates:
- most optimistic = 6 person hours
- most likely = 30 person hours
- most pessimistic = 54 person hours
Based only on the given information, which of the following answers about the three-point test estimation technique applied to this problem is true?

An anti-intrusion system is battery powered and is activated by pressing the only available button.
To deactivate the system, the operator must enter a PIN code. The system will stay in alert mode within a configurable timeout and an alarm bell will ring if the system is not deactivated before the timeout expires. The following state transition diagram describes the behavior of the system:

Assume that each test case has the following form, in which states are indicated in quotation marks and transitions in square brackets: "State 1", [Transition 1], "State 2", [Transition 2], ...,
"State N-1", [Transition N-1], "State N".
Which of the following test cases, in addition to being valid, covers all states with minimal effort?

Consider two situations:
(1) A code statement is "return x*y + z", but should be "return
x*(y+z)"
(2) For the input x=2, y=3, z=4 the system returns 10, but should
return 14
Which of the following is TRUE?

Which of the following statements about the testing quadrants is TRUE?

Which of the following statements is incorrect regarding the involvement of testers in the software development lifecycle (SDLC)?

As a result of the joint evaluation of a product version with the customer, it has been concluded that it would be appropriate to retrieve an earlier version of the product and carry out a benchmark. Depending on the result, further development will be carried out based on the current version or the retrieved version.
Which mechanism, process, and/or technique will allow the specific version (including the testing work products) of a given software product to be restored?
