Exercise on Calculating the Path

Path Formular

Example

Based on the diagram 1, the red color (dots) that has been labeled is representing the nodes, while the normal black color (line) is representing edges.

How to calculate

1. Identify and total up the nodes. N = 6 nodes.
2. Next identify and total up the edges. E = 8 edges/paths.
3. Apply the formular.

CC = E - N + 2

CC = 8 - 6 + 2

CC = 4.

How to find Length( Path )

Based on the diagram 1, we can find path at 4 or more length.

Path with 4 length:-

1. A - I
2. A - B - C - D
3. A -B - X -D
4. A - C ...

_________________

1. A - B - C - D - I
2. A ....

The path that has been selected can't be taken twice. So we will add the next path as (...), for example path(length) at no 4.

If 'A' has been chosen as the first starting point, the next path(length) also need to start with 'A'.

QUIZ (6/9/07)

Last week, on Thursday (6/9/2007), we had a quiz based on chapter 8. This quiz is based on our knowledge whether we had read chapter 8 or not, because there is no lecture on chapter 8 in class yet on that day.There are 3 questions;

Question 1
List 4 types of faults.

Answer
1)Algorithmic fault
2)Computation and precision fault
3)Documentation fault
4)Performance fault

Question 2
Who performs testing and why?

Answer
Independent test team
A team that performs most of system and launch testing independently from the teams that developed the system or application to;
-avoid conflict
-improve objectivity
-allow testing and coding concurrently

Question 3
List 2 types of testing and briefly explain.

Answer
1)Bottom-up
- Technique of integration testing. It is also the sequence of tests and their dependencies.
Example:



2) Big-bang
- Requires both stubs and drivers to test the independent components.
Example:
