What is the difference between a use case and a test case?

  Hello,

    In this blog, I'm going to explain about What is the difference between a use case and a test case?

Use case and Test case:

    Use Cases and Test Cases are two important terms in context of Software Testing. A use case tells how a System will behave or perform a certain task provided the given conditions and a test case contains the actual test data, set of instructions to system and expected result of the interaction with system.

     Important difference between Use Case and Test Case.

Sr. No.	Key	Use Case	Test Case
1	Objective	The objective of Use case is to a certain output after the set of operations.	The objective of test case is to ensure that system is working fine for each given instruction and yields the required result.
2	Definition	Use case is a representation of actions which describes the behavior's of system to do a particular task.	Test case contains the test data, set of instructions to follow and a result(s) of following the instructions.
3	Source	Use cases are prepared on requirements.	Test cases are prepared on Use cases.
4	Required	Requirement documents.	Test Data, Test Scripts.
5	Output	End result is important and all steps are to be executed together in a use case.	All steps are important and may have a separate result.
6	User	Business users executes use cases.	Testers executes test cases.
