Fundamentals of Testing
•Enough testing has been performed when:
a) Time runs out
b) The required level of confidence has been achieved
c) No more faults are found
d) The users won’t find any serious faults
Answer: b
• Deciding how much testing is enough should take into account:
• i. Level of risk including technical and business product and project risk
• ii. Project constraints such as time and budget
• iii. Size of the testing team
• iv. Size of the development team
a) i,ii,iii are true and iv is false
b) i,,iv are true and ii is false
c) i,ii are true and iii,iv are false
d) ii,iii,iv are true and i is false
Answer: c
• According to the ISTQB Glossary, the word “bug” is synonymous with which of the
following:
a) Error
b) Incident
,c) Defect
d) Mistake
Answer: c
• A phone is ringing in an adjacent cubicle momentarily distracts a programmer, causing him
to improperly program the logic that checks the upper boundary of an input variable. Later,
during system testing, a tester notices that this variable accepts input values. The improperly
coded logic for the upper boundary check is:
a) The error
b) The defect
c) The root cause
d) The failure
Answer: b
• Software testing activities should start:
a) When the requirements have been formally documented
b) As soon as possible in the development life cycle
c) During the design stage
d) During the stakeholder meeting
Answer: b
•When what is visible to the end-user is a deviation from the specific or expected behavior,
this is called:
a) An error
b) A fault
c) A failure
d) A defect
e) A mistake
Answer: c
• A company recently purchased a commercial off-the-shelf application to automate its
bill-paying process. They now plan to run an acceptance test against the package prior to
putting it into production. Which of the following is their most likely reason for testing?
a) To train the users
b) To gather evidence for a lawsuit
c) To detect bugs in the application
d) To build confidence in the application
Answer: d
,•According to the ISTQB Glossary, risk relates to which of the following?
a) Negative consequence that could occur
b) Negative consequence that will occur
c) Negative consequence for the test object
d) Negative consequences that have occurred
Answer: a
•Debugging is:
a) Checking that no unintended consequences have occurred as a result of a fix
b) Testing/checking whether the software performs correctly
c) Identifying the cause of a defect, repairing the code, and checking the fix is correct
d) Checking that a previously reported defect has been corrected
Answer: c
•When is testing complete?
a) When there is enough information for sponsors to make an informed decision
about the release
b) When time and budget are exhausted
c) When there are no remaining high priority defects outstanding
d) When every data combination has been exercised successfully
Answer: a
• A test team consistently finds between 90% and 95% of the defect present in the system
under test. While the test manager understands that this is a good defect detection
percentage for her test team and industry, senior management and executives remain
disappointed in the test group saying that the test team misses too many bugs. Given that
the users are generally happy with the system and that the failures which have occurred
have generally been a low impact, which of the following testing principles is most likely to
help the test manager explain to these managers and executives why some defects are
likely to be missed
a) Exhaustive testing is impossible
b) Pesticide paradox
c) Defect clustering
d) Absence of errors fallacy
Answer: a
•A programmer is working on code that is very complex. Which of the following is a general
testing principle that may affect his work?
, a) Defect clustering
b) Pesticide paradox
c) Exhaustive testing is impossible
d) Absence of errors fallacy
Answer: a
•What is COTS:
a) Commercial on-the-shelf software
b) Commercial off-the-shelf software
c) Common Offshore testing software
Answer: b
•Which of the following is a major task of test planning:
a) Determining the test approach
b) Preparing test specifications
c) Evaluating exit criteria and reporting
d) Measuring and analyzing results
Answer: a
• The following statements relate to activities that are part of the fundamental test process.
(i) Evaluating the testability of requirements
(ii) Repeating testing activities after changes
(iii)Designing the test environments set up
(iv)Developing and prioritizing test cases
(v) Verifying the environment is set up correctly Which statement is true
1-(i) and (iii) are part of analysis and design, (ii), (iv), and (v) are part of test
implementation and execution
2-(i) and (ii) are part of analysis and design, (iii), (iv), and (v) are part of test implementation
and execution
3-(i) and (v) are part of analysis and design, (ii),(iii), and (iv) are part of test implementation
and execution
4-(i) and (iv) are part of analysis and design, (ii), (iii), and (v) are part of test implementation
and execution
Answer: 1
•Which of the following is a fundamental test activity?
a) Test Planning and Design
b) Test Implementation and Execution
c) Evaluating Entry Criteria and Reporting
