08 Boundary Testing

Question 1

Input Domain Testing Process

Answer 1

1. Identify Inputs
2. Partition inputs space into sub-domains
3. Analyze each sub-domain
4. Select Test points.
5. Test
6. Boundary Testing

Question 2

Partition Boundary Problems Types

Answer 2

Closure Problem
Boundary Shift
Boundary Tilt
Missing Boundary
Extra Boundary

Question 3

Extreme Point Combination (EPC)

Answer 3

Test the limits of the system.

Requirements:
- Set of test points for each sub-domain.
- Analysis to identify limits of each sub-domain.
- Produce all possible combinations of limits.

Question 4

Test Case for EPC

Answer 4

(4^n) + 1
n = the dimension.

Question 5

Extreme Point Combination works well with:

Answer 5

Closure Problem
Missing Boundary

Question 6

Weak Nx1

Answer 6

Choose N points ON the boundary and 1 point OFF the boundary.

For each boundary, choose n boundary points.

Total Points: (n + 1) x b + 1
b = boundaries.

Question 7

OFF point

Answer 7

Pick the OFF point so close to the boundary that any small amount of boundary change would change the processing mode of the test points/cases defined.

The OFF point should be on the side of the boundary that will receive different processing than the boundary points.

Question 8

Boundary Relationship with OFF point

Answer 8

Closed Boundary => external point. ([ ])

Open Boundary => internal point. ( () )

Question 9

Weak Nx1 works well with:

Answer 9

Closure Problem
Boundary Shift
Missing Boundary

Question 10

___ should be a primary candidate for boundary testing

Answer 10

Weak 1x1

Question 11

___ is useful in highly constrained situations (boundaries are well aligned)

Answer 11

EPC
