Thread: What is exact difference between use case ,test scenario and test case?

Hi all, give me best example to usecase,test scenario,test case?

1. Use case:
It will be developed by Business Analyst based on the requirement specification.
It is a detailed description of the Specification in a simplified version with realtime scenarios.
Based on Use case, test cases will be written by the testers.

2.Scenario:
While writing a test case for a module, you write different tests for that module say, Creating a user.
There may be several ways to create a user like, creating a user thru wizard or thru uploading set of users.
These are all the things we can call as a scenario. This is the literal meaning.

Test case:

What are all the steps we should follow for creating a user using a wizard and
What are all the steps we should follow for creating a user using upload are called as test case.

Lets consider a library management system:

Usecase:
The functions performed by different entities(Customer, Staff, Manager) is mentioned in Usecase. a) Staff enters customer information.

Test Scenario:
Test cases are written based on scenario. Test scenarios are very brief.
a)Staff enters customer information
b)Customer returns a book

Test Cases:
Test cases are derived from scenarios. They are step by step instructions. They are very detailed and also contains actual results and expected results along with other fields
a. Enter customer information(Name, address, ph no)
b. Click on save.

can anybody give the correct ans for the usecase

Use Case:

Use case are the documents that are made by the business analyst. In this document business analyst describes all the requirements on the basis of business needs.

Test scenario:

Test scenario specify all the functionality of the application that need to be tested

Test Case:

Test case specify all the steps that are need to test the functionality

Test Suite:

Group of test cases are called test suite.

hi friend..

Hi Deepasree,

Your provide link is not saying about "use cases" that is for test cases and test scenario.

Use Case : The use case technique is used in software and systems engineering to capture the functional requirements of a system

Test scenario : Test scenarios are test cases or test scripts, and the sequence in which they are to be executed.

Test case: Test cases is a sequence of steps to test the correct behavior of a functionality/feature of an application

Use Case: A sequence of transactions in a dialogue between a user and the system with a tangible result.

Test Scenario: It is a document specifying a sequence of actions for the execution of a test.

Test Case: A set of input values,test execution preconditions,expected esults and execution postconditions developed for a particular objective or test condition,such as to verify compliance witha specific requirement.

hi srinu,

hope now you are able to get the difference between the terms

Thanks

hi,

did you go through them and got an idea reagrding the terms

Thanks

Used Case is nothing but detail description of User requirements and detailed functional flow
this is a reference document of testing phase and development phase

Use case: the description of requirements with clear information step by step.

Scenario: end to end scenario, from first page to last page.

test case: for each and every attribute

hi
Here is the difference

Use cases are means of capturing functional specifications.Use case diagrams explains you how the business flow is. To be more specific it explains you the interaction between
the actor and the system.

Test Scenario define a business flow from start point to end point. let take an example suppose Search form.there would 2 scenarios for this
1) Simple search by keyword
2) Search by Location.

Test Case is prepared to check the Functionality of the system. It consist of Step for function,Step description,Actual result and Expected result.its main objective is to check the functionality of the system whether its meets the client specification or not.


hope this might help you

test scenario is actually the events that occurs during testing.
test case is actually a document which contain procedure to test a feature.
use case is the pictorial representation of test scenario

The main difference are;

Usecase:
The functions performed by different entities(Customer, Staff, Manager) is mentioned in Usecase. a) Staff enters customer information.

Test Scenario:
Test cases are written based on scenario. Test scenarios are very brief.
a)Staff enters customer information
b)Customer returns a book

Test Cases:
Test cases are derived from scenarios. They are step by step instructions. They are very detailed and also contains actual results and expected results along with other fields
a. Enter customer information.
b. Click on save.
