ISTQB - Exam 1

According to ISTQB Syllabus, A human being can make (A), which produces (B) in the program code, or in a document. Which of the following combination is correct?...

• A- Fault, B- Mistake

• A- Fault, B- Error

• A- Defect, B- Bug

• A- Error, B- Fault

Which of following is NOT correct regarding of Testing and Quality?

• Testing can give confidence in the quality of the software if it finds few or no defect.

• A properly designed test that passes reduces the overall level of risk in a system.

• Testing should not be integrated as one of the quality assurance activities for independent.

• By understanding the root cause of defects found in other project, testing processes can be improved.

As a test leader you are collecting measures about defects. You recognize that after the first test cycle – covering all requirements – subsystem C has a defect density that 150% higher than the average. Subsystem A on the other hand has a defect density that is 60% lower than the average. What conclusions 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 still more hidden defects. Therefore we need to test subsystem C in more detail.

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

• Because we have already found many defects in subsystem C we do not need to test it much more.

• Observed defect density does not allow any conclusions about the amount of additional testing.

Which of following is suitable explanation about testing principle,… One tester has tested software applications running on mobile phone for 5 years. He has great deal of information for testing the applications and is able to test faster than anyone else. However, he has not put sufficient efforts for deriving new test cases and modifying them to find new defects any longer, which led to finding less and less defects. What is the basic test principle that he has ignored?

• Early testing

• Pesticide paradox

• Absence-of-errors fallacy

• Defect clustering

Below shows several levels of independence defined. Which of following has lowest independence?

• Tests designed by the person who wrote the software under test.

• Tests designed by another person

• Tests designed by a person from a different organizational group or test specialists.

• Tests designed by a person from a different organizational or company

Which of following activity is NOT related with Test implementation and execution the fundamental test process?

• Creating test suites from the test procedures for efficient execution

• Verifying that the test environment has been set up correctly

• Identifying necessary test data to support test condition and test cases.

• Finalizing, implementing and prioritizing test case including the identification test data.

Which of the following test aspects is important for “maintainability”?

• Response time [in milliseconds]

• Memory use [in kilo- or megabyte]

• Robustness

• Modularity

Which of following describes the testing level that tests interfaces between components, interaction with different parts of a system such as the operating system, file system and hardware, and interfaces between systems?

• System Testing

• Acceptance Testing

• Component Testing

• Integration Testing

In any life cycle model, there are several characteristics of good testing. Which of following is NOT related?

• Testers should be involved in reviewing documents as soon as drafts are available in the development cycle.

• For every development activity, there is a corresponding testing activity

• Each test level has test objectives specific to that level

• The analysis and design of tests for a given test level should not begin during the corresponding development activity.

Developers of market, of COTS software often want to get feedback from potential existing customers in their market before the software product is put up for sale commercially. This testing is performed at the developing organization’s site but not by developing team. What is this testing?...

• User Acceptance Testing

• Operational Testing

• Alpha Testing

• Beta testing
