Black Box Testing Technique : Pairwise Testing (All-pairs testing) - Part3

Pairwise Testing (All-pairs testing) 

After we have installed CTE XL which is one of software testing tools for Pairwise Testing (All-pairs testing), we will start using it with following scenario.


CTE XL: How to use

I will use this following scenario for test case design in this example.

Scenario

System: Fund Transfer feature in ATM system of A Bank with 3 dependent factors:

1st factor: How to transfer

- A Bank to A Bank

- A Bank to B Bank
2nd factor: Amount of money
- Less than $1.00
- Between $1.00 and $5,000
- More than $5,000
3rd factor: SMS alert?
- Yes
- No

Step

1. Start CTE XL.


2. Press "Ctrl+N" or click at "File>>New" menu to create a project.

3. Click at “Create New Classifications.” Button and then click in diagram 3 times to create each factor. Double Click each box and type the factor’s name.

4. Click at “Create New Classes” Buttonand then click in diagram 7 times to create each value of each factor. Double Click each text and type the value’s name.

5. Click at “Activate connection mode” buttonand then link between each value with its factor. Click at “Auto Layout” buttonto adjust diagram.

6. Click at “Tools >> Generate Test cases…” menu. The “Test case generator Editor” displays.

7. Click at “New” button. Enter the name and press “OK” button.

8. Click at “twowise” button. Drag the factor’s name from diagram and drop to “Test Case Generator Editor”. Separate each factor by “,”.

9. Click at “Generate !” button. Click “Ok” button to close. There will be a folder appears on the bottom-left pane.

10. Expand the tree. The list of possible test case will appear.

11. Extract test cases by clicking at “File >> Export” menu. Select “TestCases in Excel” format. Click at “Next” button. Update the output file folder and click “Finish” button. Open saved file.

12. Let’s use this list for testing.

The number of test case is 6 which is smaller number than testing all combination with 2*3*2 = 12 test cases.

Now we are at the end of Pairwise Testing (All-pairs testing) articles. I hope it will help you understand the concept of testing a software (testing web or windows application) by using Pairwise Testing (All-pairs testing) testing technique and know how to used CTE XL, one of software testing tools.
