ISTQB Question Dumps For Software Testing -  Part 5

 
 
Question:
 

You have been assigned to test the new Triangle Determination Application. The screen consists of three text fields and a single button. The user is expected to enter an integer value into each of the
three text fields. Upon hitting the OK button the program will print a message in a separate dialog box stating whether the triangle is scalene (all sides are different lengths), isosceles (two sides are the same length), or equilateral (all three sides are the same length). Write a set of test cases (i.e. specific sets of data) that you feel would adequately test this program. Write the tests so that someone other thanyou can run them.
 
Answers:
 
Do you have a test case:
1. for a valid scalene triangle?
2. for a valid equilateral triangle?
3. for a valid isosceles triangle?
4. for each of the three permutations of two equal sides in valid isosceles triangles?
5. in which one side has a length of zero?
6. in which one side has a negative length?
7. in which the sum of the length of two sides is equal to the length of the third?
8. for each of the three permutations of case 7?
9. in which the sum of the length of two sides is less than the length of the third?
10. for each of the three permutations of case 9?
11. in which all side lengths are zero?
12. which uses non-integer input values?
13. which uses the wrong number of input values?
14. did all your test cases specify the expected output?
Myers states that experienced professional programmers score on average 7.8 out of the first 14 questions. Extra points can be given for further tests such as performance, reliability and configuration

What is LCSAJ Testing?

Image
LCSAJ testing requires a model of the source code which identifies control flow jumps (where control flow does not pass to a sequential statement). An LCSAJ (Linear Code Sequence and Jump) is defined by a triple, conventionally identified by line numbers in a source code listing: the start of the linear code sequence, the end of the linear code sequence, and the target line to which control flow is transferred. Test cases shall be designed to exercise LCSAJs. For each test case, the following shall be specified: - the input(s) to the component; - identification of the LCSAJ(s) to be executed by the test case; - the expected outcome of the test case.

1. Which of the following statements contains the correct use of the terminology? a) a fault by a person may introduce an error into the software that may cause a failure in operation b) a failure by a person may introduce a fault into the software that may cause an error in operation c) an error made by a person may introduce a fault into the software that may cause a failure in operation d) an error made by a person may introduce a failure into the software that may cause a fault in operation e) a failure by a person may cause an error in the software that may cause a fault in operation 2.   A reliable system will be one that: a) is unlikely to be completed on schedule b) is unlikely to cause a failure c) is likely to be fault-free d) is likely to be liked by the users e) includes a minimum number of components 3.   Which of the following statements about ‘Integration Testing in the Small’ is false? a) It can combine all the components ...

What is State Transition Testing?

Image
State transition testing uses a model of the states the component may occupy, the transitions between those states, the events which cause those transitions, and the actions which may result from those transitions. The model shall comprise states, transitions, events, actions and their relationships.   The states of the model shall be disjoint, identifiable and finite in number.   Events cause transitions between states, and transitions can return to the same state where they began.   Events will be caused by inputs to the component, and actions in the state transition model may cause outputs from the component. The model will typically be represented as a state transition diagram, state transition model, or a state table. Test cases shall be designed to exercise transitions between states.   A test case may exercise any number of transitions.   For each test case, the following shall be specified: -   the starting state of the component  ...
