Test Case

Use Cases represents functional requirements

and these functional requirements need to be tested.

 
Use Case:
Use Cases represents functional requirements which represent the interactions (or observed behaviors) associated with achieving or abandoning a goal.
 A use case scenario represents one of the possible paths through a use case.
 
Test Case:
and these functional requirements need to be tested. Test case represents one set of inputs that exercises a single use case scenario. 
 
 
let me explain a bit in easy wording,
bht say chotay chotay cases mil k aik complete project bnanay mein help krtay hein. ye cases kia hein, all the functionalities which a project is required.
for example a project have functionality to
 
Sign Up, Editing a Profile, Upload and Delete pics, Delete account, Sign Out.
 
all these are 'Cases'.
you will have to choose every single case separately, which is called 'Use Case' means the case which you are using currently or working with.
 
 Now every Case is need to be tested to make sure that we have not only done this functionality but also have tested with this result.
so, Use Case after examine with expected result is called 'Test Case'.
 
Example is given by Rabia. as well you also can take idea from CS504, in lec6, at page 36
