Questions about " Fundamentals of Software Testing"
1. Which of following is NOT a "Test Analysis and Design" activity in
"Fundamental Test Process"?
a) Creating test suites from the test procedures for efficient test execution
b) Identifying necessary test data to support the test conditions and test
cases
c) Identifying and prioritizing test conditions based on analyses of test item,
the specification, behavior and structure of the software
d) Creating bi-directional traceability between test basis and test cases - -a
-2. As a tester, you are collecting measures about defects. You recognize
that after the first test cycle-covering all requirements-subsystem C has 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 the average. What
conclusions for the next test cycle could you draw from this
a) Because we have already found many defects in subsystem C we do not
need to test it
much more.
b) 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
c) Observed defect density does not allow any conclusion about the amount
of additional testing.
d) We focus testing on subsystem A, because we have found fewest defects
in that module so far - -b
-3. You are running a written test which other testers have run previously. In
addition this test has found bugs previously, and these bugs have been
confirmed to be fixed. The test manager has encouraged you to vary the
specific way in which you run the test, in the order of certain actions, the use
of mouse versus hot-keys, and the particular.......values, based on the way
users will use to the system. Which of the following is testing principle that
could explain the test manager's directive?
a) Early testing
b) Absence of errors fallacy
c) Random testing
d) Pesticide paradox. - -b
-4. Which of the following are conclusion you could draw from the test
principles?[K3]
A. Safety critical systems are tested exhaustively.
, B. The testing coverage required in one organization may not be appropriate
in another organization.
C. Risk assessment is required to understand how much testing is enough for
each system
D. Safety critical systems are likely to need more coverage than non-safety
critical system
E. Web sites cannot be tested because of the vast number of combinations of
platform, browser, internet route and navigation options.
a) A, D and E are reasonable conclusions, the others are not
b) B , C and D are reasonable conclusions, the others are not
c) B , C and E are reasonable conclusions, the others are not
d) B, D, and E are reasonable conclusions, the others are not - -b
-5. Below is a description about Regression testing. Which of following is
correct about?
a) During regression test all already executed tests are repeated after the
unit, build or system under test is modified in order to assure that changes of
the test object have not created new defects.
b) During regression test all already executed are repeated after the unit,
build or system under test is modified in order to check if the defects found
so far are corrected
c) During regression test a part of the already executed test are repeated
after the unit, build or system under test is modified, in order to check that
the changes have NOT created new defects.
d) During regression test a part of the already executed tests are repeated
after the unit, build or system under test is modified in order to check if the
defects found so far are corrected. - -c
-6. Which is a correct explanation about non functional testing?..[K2]
a) Non functional testing shall not be executed in component testing,
because non functional testing is required to integrate whole finctions.
b) Non functional testing is a testing which measure and judge various
quality attributes.
c) Non functional testing shall be executed based on ISO/IEC 9126 ( Software
Product Quality)
d) Non functional testing is a testing which requires inspirations and
experiences, and has difficulty with numeric evaluation. - -b
-7. Which of following is NOT correct regarding of Iterative-incremental
Development Models? [Kl]
a) This is the process of establishing requirements, designing, building and
testing a system in a series of short development cycles.
b) This model demonstrates the relationships between each phase of the life
cycle and its associated phase of testing
c) A system that is produced using this model is tested at several test levels
during each iteration
