Types of Testing

Question 1

Describe Regression Testing

Answer 1

Running tests that the software has already passed after defects are removed.

Question 2

What is integration Testing?

Answer 2

Testing to ensure that two or more modules communicate with each other as intended

Question 3

Explain what is meant by unit testing.

Answer 3

Testing a module to make sure that it works as intended.

Question 4

What is retesting?

Answer 4

Rerunning tests that the software failed before, after a defect has been removed.

Question 5

What is system testing?

Answer 5

System Testing is testing the fully integrated application including external peripherals
and systems to determine how they interact with each other.

Question 6

What is the criteria for system testing?

Answer 6

Complete application should be developed
*
Unit Testing must be completed
*
Integration Testing must be completed
*
External dependencies and
schedules
are ready

Question 7

Describe user acceptance testing.

Answer 7

Acceptance Testing is a formal testing conducted to determine whether a system satisfies its acceptance criteria.

Question 8

List and describe the three approaches of integration testing.

Answer 8

Big Bang:
All features are integration simultaneously. There is a big disadvantage to
this method as it is time
-
consuming and difficult to trace the cause of failures.
2.
Incremental:
All units are integrated one by one and test is carried out after each
step. Disadvantage of this approach is that it is time
-
consuming since stubs have to
be developed.
3.
Sandwich Testing:
Integration starts from the middle layer and moves

Question 9

What criteria must be met for acceptance testing?

Answer 9

There are three major objectives of Acceptance Testing:
1.
Confirm that the system meets the agreed upon criteria
2.
Identify and resolve discrepancies, if there is any
3.
Determine the readiness of the system for cut
-
over to live operations

Question 10

What are the two types of acceptance testing?

Answer 10

There are two types of acceptance
testing:
1.
User Acceptance Testing (UAT)
–
It is conducted by the customer to
ensure that system satisfies the
contractual acceptance criteria
before being signed
-
off as meeting
user needs.
2.
Business Acceptance Testing (BAT)
–
It is undertaken within the
organization to ensure that the
system will eventually pass the user
acceptance testing
