1.1.7 Various types of testing

Question 1

what is functional testing?

Answer 1

they test individual commands, text input, menu functions, etc. it confirms that they perform and function correctly according to design specifications

Question 2

what is data testing?

Answer 2

when normal, abnormal, and extreme data is put into the system.

Question 3

what is extreme data?

Answer 3

you’ve entered something impossible or entered the limits of something that is not logical. Data that isn’t in the ranges of something possible

Question 4

what is abnormal data?

Answer 4

an abnormal value is a value that does not belong to the normal data distribution. Values that are invalid

Question 5

what is normal data?

Answer 5

typical data that the program should accept and be able to process

Question 6

What is Data at the limits?

Answer 6

w

Question 7

what are the types of data testing?

Answer 7

alpha testing, beta testing, dry-run, unit testing, integration testing, user acceptance, debugging

Question 8

what is alpha testing?

Answer 8

done before the software is made available to the general public. will be carried out by the company that develops the software in a laboratory type environment

Question 9

What is beta testing?

Answer 9

includes comments and suggestions from users. users outside the company involved in the testing. Their feedback can be used to fix errors that were missed. last minute software changes. Made available to the general public.

Question 10

What is Dry run testing?

Answer 10

conducted using pen and paper by the programmer. during testing programmer mentally runs the algorithm. Examines source of code and decides what the output of a run should be.

Question 11

What is unit testing?

Answer 11

testing individual parts of a system separately

Question 12

what is integration testing?

Answer 12

entire system is tested at the same time that all components can work together

Question 13

What is user acceptance testing?

Answer 13

used to determine if the system satisfies costumer needs. conducted in user premises before accepting transfer of ownership. This testing is the last stage of software testing process

Question 14

what is debugging testing?

Answer 14

systematic process of finding and correcting the number of bugs (errors) in a computer program

Question 15

Can some computers automatically test other programs?

Answer 15

Yes, and this makes the testing process faster and cheaper

Question 16

What is validation?

Answer 16

process of evaluating whether data input follows appropriate specifications. It’s the confirmation that a computer product meets its design function or is appropriate for the intended use. (validation: process of evaluating)

Question 17

What is verification?

Answer 17

confirmation that a computer meets identified specifications. (verification: process of ensuring)

Question 18

Some examples of a validation question

Answer 18

are we developing the correct system?

Question 19

some examples of a verification question?

Answer 19

are we developing the system correctly? Does the product meet the costumers needs? Does the product comply with a specific regulation or condition?
