ISTQB software testing questions.

Questions and Answers

1.

Deciding how much testing is enough should take into account:i) Level of risk, including technical and business product and project riskii) Project constraints such as time and budgetiii) Size of the testing teamiv) Size of the development team
- A.
  
  I, ii, & iii are true; iv is false
- B.
  
  I & iv are true; ii & iii are false
- C.
  
  I & ii are true; iii & iv are false
- D.
  
  Ii, iii & iv are true; i is false
Correct Answer
C. I & ii are true; iii & iv are false

Explanation
"Size of the development team" is false because this will not necessarily determine how complex the software is and/or how much testing it needs.

"Size of the testing team" is false because this gives no indication of how much testing is needed (it relates only to our capacity to do the testing).

One of the fields on a form contains a text box which accepts alphabets in lower or upper case. Identify the invalid Equivalence Class value.
- A.
  
  TESTING
- B.
  
  TESTING
- C.
  
  TEsting
- D.
  
  TEst67g
Correct Answer
D. TEst67g

Explanation
An Equivalence Class (or Partition) is a portion of the input or output domain for which the behaviour of the system is assumed to be the same, according to the specification. There is no mention of allowing digits in the specification.

3.

Repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes in the software being tested or in another related or unrelated software component is known as:
- A.
  
  Re-testing
- B.
  
  Confirmation testing
- C.
  
  Regression testing
- D.
  
  Negative testing
Correct Answer
C. Regression testing

Explanation
Re-testing and confirmation testing relate to checking that a defect has been fixed. Negative testing is testing with the intention of breaking the system.

Defects discovered by static analysis tools include:i) Variables that are never usedii) Security vulnerabilitiesiii) Programming standard violationsiv) Uncalled functions and procedures
- A.
  
  i, ii, iii & iv are true
- B.
  
  Iii is true; i, ii & iv are false
- C.
  
  I, ii, iii & iv are false
- D.
  
  Ii & iv are true; i & iii are false
Correct Answer
A. i, ii, iii & iv are true

Explanation
Static analysis is the analysis of code without executing it. This can also be done on documentation, and can even be carried out by software.

The structure of an incident report is covered in the Standard for Software and System Test Documentation (IEEE 829), where it is called a(n):
- A.
  
  Anomaly report
- B.
  
  Defect report
- C.
  
  Test defect report
- D.
  
  Test incident report
Correct Answer
A. Anomaly report

Explanation
This is just something you have to know, and it's worthwhile flipping through IEEE 829.

In the following code fragment:Disc = 0Order-qty = 0Read Order-qtyIf Order-qty >= 20 then Disc = 0.05 If Order-qty >= 100 then Disc = 0.1 End ifEnd ifWhat is the minimum number of tests you would need for full statement coverage?
- A.
  
  4 tests
- B.
  
  1 test
- C.
  
  3 tests
- D.
  
  2 tests
Correct Answer
B. 1 test

Explanation
As long as you had Order-qty being 100 or greater, all the statements would be executed.

IMPORTANT: Don't get "statement coverage" confused with "decision coverage".
