Answer / vinu
Precondition is nothing but the settings/conditions
required to execute the test case.
Ex:Precondition for pen is as follows
1.Pen should have sufficient ink
Steps:
1.Write on white paper using same pen
Expected out put:
1.All the letters should be properly visible
Note:Precondition is different from expected output
I can tell post condition is nothing but the expected out
put.

Answer / pratik
a postcondition is a condition or predicate that must always
be true just after the execution of some section of code or
after an operation in a formal specification. Postconditions
are sometimes tested using assertions within the code
itself. Often, postconditions are simply included in the
documentation of the affected section of code.
For example: The result of a factorial is always an integer
and greater than or equal to 1. So a program that calculates
the factorial of an input number would have postconditions
that the result after the calculation be an integer and that
it be greater than or equal to 1.

Answer / chahal
Precondion is pre setting that tester needs to run that
test case for example a registered user needs to activate
by administrator (from back end) before he/she use his/her
account. so when tester will write test cases for login
then he/she will mention it in pre condition "User has
activated by administrator". one thing more Pre-condition
is always written with prefect tense

Answer / ganesh ram j
Iḿ making it simple, preconditions is the state or
environment that should be active to execute the test
scenario for example take a login screen - here
preconditions is Launch the app, after splash screen, wait
till login screen loads. So from here actual test scenario
begins.
Post conditions is nothing but expected result after test
scenario executed end result.

Pre-condition whatever there is inside or outside of the
system, that will affect how the system will handle the
test. The current state of the system and/or environment
before you run the test case.
Post-condition – anything you expect to happen as a result
of running the test case.
Changes in the state of the system and/or environment as a
result of running the test case.
