Difference Between Test Case and Test Scenario In Flutter
Hi everyone! today we explore the Difference between Test Case and Test Scenario In Flutter. A test scenario is any potential capacity that may be tested, whereas a test case is a collection of operations performed to verify certain features or functionality. Test Cases are derived from test scenarios, whereas Test Scenarios are derived from test artifacts like BRS and SRS.

Best practices for Creating Test Cases
What is the Test Case?
A test case is a series of operations carried out to validate a certain aspect or capability of your software program. A test case includes test procedures, test information, preconditions, and postconditions that were created for a particular test scenario to validate any requirement. The test case contains particular variables or conditions that a testing engineer might use to compare expected and actual outcomes to ascertain whether a software product is operating by client requirements.
What is a Test Scenario?
A Test Scenario is defined as any functionality that can be tested. It is a collective set of test cases that helps the testing team to determine the positive and negative characteristics of the project.
Test Scenario gives a high-level idea of what we need to test.
Example of Test Scenario:
For an eCommerce Application, a few test scenarios would be
- > Test Scenario 1: Check the Search Functionality
- > Test Scenario 2: Check the Payments Functionality
- > Test Scenario 3: Check the Login Functionality
KEY DIFFERENCE:
- A test Case is a set of actions executed to verify particular features or functionality whereas a Test Scenario is any functionality that can be tested.
- Test Case is mostly derived from test scenarios while Test Scenarios are derived from test artifacts like BRS and SRS.
- Test Case helps in exhaustive testing of an application whereas Test Scenario helps in an agile way of testing the end-to-end functionality.
- Test Cases are focused on what to test and how to test while Test Scenario is more focused on what to test.
- Test Cases are low-level actions whereas Test Scenarios are high-level actions.
- Test Case requires more resources and time for test execution while Test Scenario requires fewer resources and time for test execution.
- Test Case includes test steps, data, and expected results for testing whereas Test Scenario includes an end-to-end functionality to be tested.
Example of Test Cases:
Test cases for the Test Scenario: “Check the Login Functionality” would be
- Check system behavior when a valid email id and password are entered.
- Check system behavior when an invalid email id and valid password are entered.
- Check system behavior when a valid email id and invalid password are entered.
- Check system behavior when an invalid email id and invalid password are entered.
- Check system behavior when email id and password are left blank and Sign in entered.
- Check Forgot your password is working as expected
- Check system behavior when a valid/invalid phone number and password are entered.
- Check system behavior when “Keep me signed” is checked
Why do we write Test Cases?
Here, are some important reasons to create a Test Case-
- Test cases assist in confirming compliance with relevant standards, directives, and client needs.
- It helps you to validate expectations and customer requirements
- Increased control, logic, and data flow coverage
- You can simulate ‘real’ end-user scenarios
- Exposes errors or defects
- When test cases are written for test execution, the test engineer’s work will be organized better and simplified
Why do we write Test Scenario?
Here, are important reasons to create a Test Scenario:
- The main reason to write a test scenario is to verify the complete functionality of the software application
- It also helps you to ensure that the business processes and flows are as per the functional requirements
- Test Scenarios can be approved by various stakeholders like Business Analysts, Developers, and Customers to ensure the Application Under Test is thoroughly tested. It ensures that the software is working for the most common use cases.
- They serve as a quick tool to determine the testing work effort and accordingly create a proposal for the client or organize the workforce.
- They help determine the most critical end-to-end transactions or the real use of the software applications.
- Once these Test Scenarios are finalized, test cases can be easily derived from the Test Scenarios.
Test case Vs Test scenario:
Here, are significant differences between a Test scenario and a Test Case
Test Scenario contains high-level documentation which describes an end-to-end functionality to be tested. Test cases contain definite test steps, data, and expected results for testing all the features of an application.
It focuses on more “what to test” than “how to test”. A complete emphasis on “what to test” and “how to test”. Test scenarios are a one-liner. So, there is always the possibility of ambiguity during the testing. Test cases have defined a step, pre-requisites, expected result, etc. Therefore, there is no ambiguity in this process.
Test scenarios are derived from test artifacts like BRS, SRS, etc. A test case is mostly derived from test scenarios. Multiple Test cases can be derived from a single Test Scenario. It helps in an agile way of testing the end-to-end functionality and helps in exhaustive testing of an application test scenarios are high-level actions.
Test cases are low-level actions. Comparatively less time and resources are required for creating & testing using scenarios. More resources are needed for documentation and execution of test cases.
Best practices for Creating Test Cases:
There are some following Creating Test Cases are:
- Test Cases should be transparent and straightforward
- Create a Test Case by keeping the end user in the mind
- Avoid test case repetition
- Make sure you create test cases to verify all of the software requirements listed in the specification document.
- When creating a test case, never assume the functioning and capabilities of your software application.
- Test Cases ought to be easily recognizable
Best practices for creating a Test Scenario:
There are some following Creating Test Scenario are:
- Test scenarios are mostly single line statement that tells what should be tested
- The scenario description should be simple and easy to understand
- The given needs should be carefully evaluated.
- The required tools and resources for testing need to be accumulated before the beginning of the testing process.
Conclusion:
In this section, we have understood the essential differences and importance of both test cases and test scenarios. Using both the test case and test scenario together ensures robustness and high coverage testing creativity.
Because most IT businesses prefer Test Scenarios in the current Agile era, it is recommended to prepare Test Scenarios before writing Test Cases. The test case is being replaced with test scenarios in the agile period to save time.
