What Is Test Scenario and Test Case

 

Test scenario and test cases

 

Test case consist of a set of input values, execution precondition, expected results and executed post condition, developed to cover certain test condition.

 While Test scenario is nothing but a test procedure. A Test Scenarios has one or many relations with Test Case, meaning a scenario can have multiple test cases. A TEST SCENARIO is defined as any functionality that can be tested. 

Test scenario is like what we have to test, it’s a high level test case.

Means what we have to test is considered as test scenario.

One test scenario is collection of multiple test cases.

Example of test scenario: LOGIN FUNCTIONALITY OF GMAIL.

SCENARIO: login functionality.

Test case:

1.    Valid Username Invalid Password.

2.    Valid  password invalid Username.

3.    Invalid Username valid password.

4.    Invalid password valid username.

5.    Invalid username invalid password.

6.    Valid username valid password. 

A test scenario contains a high level documentation, describing an end to end

functionality to be tested.

A test case contains clearly defined test steps for testing a feature of an application.

Test scenarios just focus on “what to test. Test cases focus on “what to test” and “how

to test”. 

Test scenarios are generally one-liner. Hence, there is always possibility of ambiguity

during testing. Test cases have clearly defined step, pre-requisites, expected results

etc. Hence, there is no ambiguity.

Test scenarios are derived from use cases .Test cases can be derived from test scenarios and have many to one relationship with them

Test scenarios are beneficial in quick testing of end to end functionality of the application. Test cases are efficient in exhaustive testing of application.

Relatively less time and resources are required for creating and testing using scenario. More resources are required for documentation and execution of test cases.
