Mr. Test has been testing software applications on mobile devices for a period of 5 years. He has a wealth of experience in testing mobile applications and achieves better results in a shorter time than others. Over several months Mr. Test did not modify the existing automated test cases and did not create any new test cases. This leads to fewer and fewer defects being found by executing the tests. What principle of testing did Mr. Test not observe?

Repeating of tests will not find new defects.

Testing depends on the environment.

Exhaustive testing is not possible.

Which objective may be obtained by having testers work closely with system designers while the system is being designed?

Increase the likelihood that the software meets stakeholder needs and satisfies requirements

Reduce the risk of incorrect or untestable functionality being developed

Which of the statements below is the best assessment of how the test principles apply across the test life cycle?

What is the definition of debugging?

Identifying the cause of a defect, repairing the code and checking the fix is correct

An android application has a bug which results in incorrect interest payments, due to a single line of incorrect code. This bug results in customer complaints. When root cause analysis was performed, the root cause was identified as the lack of product owner understanding in the interest calculations. What solution could be used to reduce the likelihood of such bugs in the future?

The product owner could be trained in the topic of interest calculations

Exhaustive testing is impossible so it is impossible to reduce the likelihood of such bugs in the future

The developer should review the user stories before they are implemented

The tester could imply the Invest technique on the user stories to ensure that they are written correctly

A new retail product was released to production by your company. Shortly after the release it was apparent that there were numerous problems with the point of sale application. This resulted in a number of customer complaints and negative postings on social media encouraging people to take their business to your competitor. You have investigated the problems and have discovered that the production point of sale equipment is a later model than the model used in testing. The software functions correctly on the old version, but fails on the later model.

The root cause is conducting the testing on the wrong version of the equipment and the effect is the customer complaints and postings

The root cause is the software failing on the later model and the effect is the customer complaints

The root cause is the old equipment and the effect is the new equipment

The root cause is the customer complaints and the effect is the social media postings

Because he was unfamiliar with the domain of fitness training, the author of the requirements wrongly assumed that users wanted heartbeat in beats per hour.

The tester of the smartphone interface had not been trained in state transition testing, so missed a major defect.

Because she had never worked on wearable devices before, the designer of the user interface misunderstood the effects of reflected sunlight

Which of the following is a correct statement?

A developer makes a mistake which causes a defect that may be seen as a failure during dynamic testing

A developer has a failure which results in a defect that may be seen as a mistake during dynamic testing

A developer makes a mistake which causes a bug that may be seen as a defect when the software is executed

A developer makes an error which results in a failure that may be seen as a fault when the software is executed

Below is a list of problems that can be observed during testing or operation. Which is MOST likely a failure?

The product crashed when the user selected an option in a dialog box

The computation algorithm used the wrong input variables

The developer misinterpreted the requirement for the algorithm

As a test leader you are collecting measure about defects. You recognize that after the first test cycle-covering all requirements – subsystem hat a defect density that is 150% higher than the average. Subsystem A on the other hand has a defect density that is 60% lower than average. What conclusion for the next test cycle could you draw from this fact?

According to the testing principle “defect clustering” it is probable that subsystem C has till more hidden defects. Therefore we need to test subsystem C in more detail

We focus testing ob subsystem A, because we have found fewest defects in that module so far

Because we are already found many defects in subsystem C we do not need to test is much more

Observed defect density does not allow any conclusion about the amount of additional testing

System test execution on a project is planned for eight weeks. After a week of testing, a tester suggests that the test objective stated in the test plan of 'finding as many defects as possible during system test' might be more closely met by redirecting the test effort according to which test principle?

Which objective may be obtained by having testers involved in requirements reviews or user story refinement?

Reduces the risk of incorrect or untestable functionality being developed

Increase the likelihood that the software meets stakeholder needs and satisfies requirements
