You have to write only one test case, under thus you have 
to write all the expected results.

My question is that If 10 test steps then 
For 2nd step   One Expected result
For 4th step   Second Expected result
For 6th step   Third Expected result
For 7th step   Fourth Expected result
For 9th step   Fifth Expected result
For 10th step  Sixth Expected result

Then May I have to create 6 test cases as 

Step1                    One Expected result
Step2

Repeat Step 1,2          Second Expected result
Step3
Step4

If I write 10 steps in one test case
then how other testers will come to know that 1st expected 
result will occure after step 2,4,6,7,9 & 10

Hi,

Yes u have to write all the 6 expected results under the 
same or single test case.no need to write it separately.(I 
mean for all the six expects results no need to write the 
Test condition,input values again and again.)u can cover it 
under a single test condition...

correct me if i am wrong..

Hi,
 yes u should write 6 expected result.
for each step u should write expected result.
EX:
Test case: sucessful Login
                                
Step1:user is in login page (Expected result)User should be 
in the login page
Step2: enter the id 'asdf@yahoo.com' in id textbox.
(Expected result)'asdf@yahoo.com'should display in the id 
textbox.
Step3:enter the password'pass'in the password textbox. 
(Expected result)'xxxx' should display in the password 
textbox 
Step4:click the sign in button (Expected result)user should 
be in homepage
