what is use case? What is the diffrence between test cases and use cases?

Use Case is a series of steps an actor performs on a system to achieve a goal.Test case describes action, event, input requirements,actual result. Test case have test case name, test case identifier, Expected result.And a use case is a technique for capturing the potential requirements of a new system or software change.

Use case is nothing but the functional specification document in which all the customer requirements are documented.

Test case is a document which tells wat to test, steps to test and expected and actual results.

 

Usecases  are High Level requirements and it's describes all Funcationalitys as per user point of view.

Test Cases are Low level requirements and it's describes the each step of the funcationality.

we will write test cases on the depend of of use case

Hi, I will give good Ex:-

Use case:-

Use Case is written in Business Design Document(BDD)by the Business Analyst.It is for understanding the functionality for the person who is involved in writing the testcases

 

USE CASE EXAMPLE

Action	Response
when OK button is clicked	Screen 1 appears

 

Test case:- Test case is different perceptions for a functionality to be tested.Usually written by Test Enginneer.The same person who has written the test case may execute them or the other person.

 

Above Use case is converted into TestCase keeping in mind different perceptions(-ve and +ve)

Action	Expected Value	Actual Value	Result
click on Ok	screen 1 should appear(+ve perception)	screen1 appeared	pass
click on ok	screen 2 should appear(-ve perception)	screen 1 appeared	fail
click on ok	screen 2 should appear(-ve perception	screen 2 appeared	pass

Hi,

Use cases are prepared by BA and it is specified in BRS.

Test cases are prepare4d by test engineers. Use cases are used to prepare test cases.

usecase describes actors actions and corresponding response of the application

test cases is a step by step process how to test the functionality of an application

usecase document is a parent document like BRD FRS SRS using which we can write test case

Use cases describe the “process flows” through a system based on its actual likely use, so the test cases derived from use cases are most useful in uncovering defects in the process flows during real-world use of the system.

Use cases, often referred to as scenarios, are very useful for designing acceptance tests with customer/user participation. They also help uncover integration defects caused by the interaction and interference of different components, which individual component testing would not see.

Use Case:a document that describes the system response for a particular input by the user

Use Case: is a design specification which describes the flow of the system.
Test Case: is a test specification which describes the areas which needed to be tested.
You can derive test cases from Use Case.

use case defines "actor action and system response", error guessing, expected value "

Test case describes "test case id, test case description, pre requisites, step no. , expected value, actual value, pass/fail status"

Use case prepared by BA and Test case will prepared by Test lead

Hi all,

Can any one tell me clearly what is use case and how it is used where it is used in the short description.

Regards,
sundar rajan.

Use case is a pictorial representation of the business logic and work flow. Use cases have a narrator or story teller and actors. It gives detailed steps to be followed and how the system is expected to respond to it. There is alternative and failure scenarios also. It is prepared by the BA and helps the QA to understand the requirement better.

Test cases are prepared by the QA after reading the requirement document and use cases.

Use case is a document that describe about user action and system respond in a particuler fuctionality of a software.
use case only one positive test case but with this use case could be lot of negetive test case. Test case is step by step prosses to test software.

use case = 1. it is a doc that describes user action ans system response. 2 it is prepared by business analyst in analysis phase in sdlc. 3 some companies use usecase document as a business req document and in some companies they use as functional specifications as brd doc.
test case = 1. it is a doc that describes the step by step approach how to execute a particular requirement. 2. it is prepared by testers in stlc in design phase. 3 this doc is used to check the test execution to gain the expected result

use case is noting but user story.
test case is step by step method to validate requirements.

Usecase is sequence of flows to achieve certain requirement.
