Test Scenario is nothing but the scenario which you are 
going to test.
Let me give you example of writing test scenario for the 
login screen in any web based application.

Consider that you need to test this screen. 
The login screen contains the Logn Name(Label)followed by 
Text box to enter login and Password (label)followed by 
Text box to enter Password. Submit Button and a Reset 
Button.

Here we needs to concentrate both on positive test scenario 
by entering all the values and clicking on the submit 
button.Negative scenarios such as invalid login name, 
invalid password etc

HI
   Test Scenario's is Testing The Combination of Test cases.
   For Example:-
   Registaring an employee Details Such as
   1. Empno
   2. Ename
   3. Job
   4. Designation
   5. Salary
   6. Deptno
   7. Date of JOining.
  Enter values for The possitive Test Scenario & Negative 
  Test Scenario's .
  (This is only example To Understand)

Test scenario is actually trying to test the Particular 
function from end to end.Its actually few test Cases that 
test the whole Product scenario.Suppose i have to login 
into Yahoomail.
for this precondition is that we have to open IE and then 
Url www.yahoomail.com.
Then second step is that we have to Type correct login id 
Followed by the correct password.
then click on Sign In.
This is a scenarion for Login into yahoo mail but in a test 
scenarion we have to cover the negative aspects and mention 
that also also.In a software system you can mention the 
Exceptions and Error or Wrong Validation etc as per the 
system Response.
I think this suffice ur query
Thanks

Hi Lavanya!
Firstly let us consider basic difference between a Scenario
and a Test case;
I would say a Test scenario is a single FUNCTIONALITY Eg;
Log in, Logout Etc.
and now a test case; here we can write number of test cases
on Login scenario, Logout scenario Etc.....

The best Eg I can give you here is, when u go to any ATM
first you select withdrawal or Mini statement, Balance
inquiry, from savings Etc.... all these are scenarios 
Take one scenario for Eg;Withdrawal- Now you can write test
cases as (1) Select Withdrawal from main menu, (2) select
account type 'from savings or from current. '(3) Enter valid
password.............soooo on.
I think now u can understand.

I think answer posted by Amika is correct. Test scenario is 
the end to end functionality test of a requirement.

Hi guys you all are partly correct and close to what a test
scenario means.I am also giving you the answer what
generally is test scenario.
Test scenario is just to test particular aspect of an
application.It is not positive and negative.Like for example
you have to test login window which will draw you to next
page if you enter correct username and password.This is one
test scenario.
Now in this scenario,you can build numerous test cases,both
positive and negative.Like for example,a username text field
should allow only alphabets and numbers with no special
characters.so for positive test cases u will enter alphabets
and numbers and to negatively test it u enter special
characters and check the actual behaviour and compare it
with expected behaviour.There can be more test cases can be
created for this only one scenario.

I hope this might have cleared your doubts.
bi guys.

Hi friends,
Test scenario is nothing but to test the Particular 
function from end to end.There is positive and negative 
tests in test scenario.Where as test cases, we first 
conduct positive test then negative test with different 
possibilities like nnumerics,alphabets,alpha numeris,  
special characters, case sensitive, name start with capital 
letter and so on. Suppose we want to send mail from your 
gmail.com
Ex: of test scenario is click on browser-->enter Url->enter 
valid username and password-->click on sign in-->click on 
compose Mail.This complete flow is nothing but a scenario.

Hi
Test Scenario is nothing but the scenario which you are

Here we needs to concentrate both on positive test scenario 
by entering all the values and clicking on the submit 
button.Negative scenarios such as invalid login name, 
invalid password etc

in basic understanding test Scenario is nothing but WHAT to 
be tested. 

here is a small example that Which can be easily understood.

For example. Testing this present screen. 

Firstly required for test scenario is that you need a test 
scenario template. where you can pick it from a folder 
structure which you created in the Configuration management 
or VSS. 

Secondly comes out for the test scenarios. 
where you are going to fill out in the scenarios template 
that WHAT to be tested 

In these process where 
all your scenarios is identified and reviewed by your peers 
or by your TL. 

Any  clarifications or any mistake please let me know. 
According  to my knowledge i projected out. 
please let me know friends.
