Boundary value testing...
- A.
... is the same as equivalence partition testing.
- B.
... tests values at the smallest incremental distance on either side of an equivalence partition boundary.
- C.
... tests combinations of input circumstances.
- D.
... is used in white box testing strategies.
Correct Answer
B. ... tests values at the smallest incremental distance on either side of an equivalence partition boundary.Explanation
For example, if valid ages are expressed in whole years and must be 18 or over, the boundary values would be 17 and 18. This is because 17 is the closest value to the boundary in the "invalid" equivalence class and 18 is the closest value to the boundary in the "valid" equivalence class.Rate this question:

How many test cases are necessary to cover all the possible sequences of statements (paths) for the following program fragment? Assume that the two conditions are independent of each other:IF (Condition 1) THEN Statement 1 ELSE Statement 2ENDIF IF (Condition 2)THEN Statement 3ENDIF
- A.
2 test cases
- B.
3 test cases
- C.
4 test cases
- D.
Not achievable
Correct Answer
A. 2 test casesExplanation
We want to end up executing all statements across our test cases.
TEST CASE ONE
Condition 1 = TRUE will execute Statement 1.
Condition 2 = TRUE will execute Statement 3.
TEST CASE TWO
Condition 1 = FALSE will execute Statement 2.
It doesn't matter what we do with Condition 2 for this test case, but I'd be inclined to do Condition 2 = FALSE because this would give us decision coverage, which is more powerful than statement coverage.Rate this question:

In which order should tests be run?
- A.
The most important tests first.
- B.
The most difficult tests first (to get the hardest work finished early).
- C.
The easiest tests first (to give initial confidence).
- D.
The order they are thought of.
Correct Answer
A. The most important tests first.Explanation
In a risk-based approach, we'd want to start with the most important tests.Rate this question:

Which of the following is the odd one out?
- A.
White box
- B.
Glass box
- C.
Structural
- D.

Correct Answer
D. FunctionalExplanation
The first three are different words for the same thing, whereas functional testing is generally black box testing.Rate this question:

- 6.
A program validates a numeric field as follows: - Values less than 10 are rejected- Values between 10 and 21 are accepted- Values greater than or equal to 22 are rejected Which of the following input value sets covers all of the equivalence partitions?
- A.
10, 11, 21
- B.
3, 20, 21
- C.
3, 10, 22
- D.
10, 21, 22
Correct Answer
C. 3, 10, 22Explanation
3 is less than 10, so it falls into the first partition.
10 is between 10 and 21, so it falls into the second partition.
22 is greater than or equal to 22 so it falls into the third partition.Rate this question:
