Alpha / Beta testing

Question 1

Black box testing

Answer 1

Here we don’t care about how the works and don’t need to understand what is happening inside the code

Test data is prepared and problems are identified using a trace table. Simply compare inputs with outputs

Question 2

Pros / Cons of blackbox testing

Answer 2

Pros:
- Cheap
- Quick
- Doesn’t need skilled workers

Cons :
- Doesn’t identify what went wrong with program
- Further investigation is required if problems are found

Question 3

White box testing

Answer 3

In this we only care about how the program works . Skilled programmers go through the code line by line. Care more about how the code functions instead of the overall function

Generally used when safety is critical and involves danger to human life (e.g. plane , car)

Question 4

White box testing pros / cons

Answer 4

Pros:
- Testers gain a real understanding
- Can help make code more efficient
- Helps with documentation
- Specific localised programs are delt with

Cons:
- Expensive
- Takes a long time
- May miss key features as they don’t have an overall view

Question 5

Answer 5

Includes both white and black box testing
Is done in house by developer

Question 6

Pros / Cons of alpha testing

Answer 6

- Faster then beta testing
- cheaper(done in house)
- Rivals and customers don’t see product

Cons:
- Software is not tested on a variety of devices

- Developers won’t use product as customers , may miss potential problems

Question 7

Answer 7

Software is distributed to beta testing customers for free , they report back any problems or potential improvements.

Question 8

Beta testing pros / cons

Answer 8

Pros:
