Question { EDS, 53412 }

What is the difference between User Acceptance Testinga and
System Testing?

Answer

In Clear Both Acceptance Testing and System Testing are
BalckBox Testing
> In User acceptance testing we consider case study of
user requirement, and check whether all the requirements
are met?
> In system testing is done soon after integration
testing, to check whether the system specification are met?

Question { Qwest, 4861 }

What is Finite state Machine in Testing?
What is High Availability Testing?
What is Incremental Regression Testing?
What is sensitivity Testing?
Plz Reply ASAP.

Answer

So Many Questions @ Once... Good

"Finite State Machine in Testing"
We represent complete module or a System with a State diagram. Based on Result of one state we are choosing next state to Test
eg: Consider amount Withdrawal state diagram

correct
start-->Check Pin-----------> withdraw money----> End
|
|Not Correct
Eject Card ---------> End

Here If PIN entered is correct then only we are moving to the state 'withdraw money' and perform Testing of Withdraw Else we are Testing 'Eject Card' functionality.


"High Availability Testing"
Availability Testing is the ability to test the disaster behavior of the system. It is the ability to test how quick the system will recover from any failure. Availability is measured in terms the time system is up during a period of time.

"Incremental Regression Testing"
Many products are developed using Incremental development Methodology. New releases may come in a day, week , or month of time. We perform regression testing on each release. Hence we are Testing New feature of every release and how it is effecting already existing features.

"Sensitivity Testing"
We define the percent of system that can behave well, may consider testing at the variable level. We observe behavior of the system at low level.

Question { 3890 }

What is Interoperability Testing?
What is Risk Based Testing?

Answer

Interoperability Testing is the ability to test
functionality on different platforms
eg: Consider requirement "System shall have the ability to
read input which comes from different OS"
If we are able to test this requirement on different OS,we
are achieving Interoperability.

Risk Based Testing.
In the Risk based testing we prioritize the testing based on
likely hood of failure functionality.
Risk based testing is chosen when there is a lack of time.
Here we are not considering the features to test which are
Expected to behave in proper.

Question { CTS, 9092 }

what is the use case and what is the test case?

Answer

Use Case is a scenario to understand actions and actors of
any requirement.
eg:- If a requirement says "Library System shall be
capable of performing Book Withdrawal" In this requirement
actors are 'Student' and 'library manager' and the action
is 'Withdrawal'

Test Case is a structure to validate any functionality. so
here with our above example we are validating Book borrow
functionality. Test Case mainly contains Four parts
1. Test Objectives : What are we testing? and what is the
data required?
2. Expected Results:
3. Test Steps:
4. Actual Results:
