For Example:
In banking system we want to test payment message received
in application/system get assigned to particular user to
work on it.
Then Precondition will be: Routing rules are set up in the
system.
Post Condition :Message get routed to respective user.

If I am testing a household plumbing system, one part of that may be the functionality of a tap (water). The Pre-Condition may be that the tap is connected to the water mains and the stop cock is open. The Expected result is - water flows from the tap and is cold (hot water tap would also need (boiler connected and operational as a pre-condition and tested first). The post-condition may be - the sink fills up (whilst some may see this as part of a result, it isn't as the plug may not be in place so therefore may not fill. This operation would be a different test) The idea of post-conditions is that they illuminate other areas of operation that may require consequential testing - as above - the sink may overflow so we need to test if the drainage of the sink works also.

Regarding Post-Condition.Often optional. In general it defines the conditions that must be met after finishing the run of the test case, or instructions what to do after running this test case.
Very often the conditions are just put into the section: Expected results.
Example: after running this test case please clean the data you have created and restore the data you have deleted.

Answer / rahul
preconditions to write a test case is nothing but you should
have the functional doc and the use case doc on the basis of
which you prepare the test case.
postcondition is the expected value after that test case is
executed.
