Terms like Test Scenarios and Test Cases are fundamental concepts used in the field of software testing. There is no difference between manual testing and automated testing. Even though test scenarios and test cases may sound similar, there are significant differences.

Test Scenarios

The Test Scenario is a high-level description of what should be tested. It is like general guidance for testing specific parts of the software or features. Test scenarios are more general and provide a broader view of what needs to be verified without delving into the details of specific steps.

The Characteristics of a Test Scenario

Generality: Describe what needs to be verified without a description of testing steps.
Wide coverage: Targets the complete functionality or module.
Simplicity: Can be described in one or a few sentences.

The Test Scenarios help to identify the part of the software, which needs to be verified. They provide a basic framework for creating detailed test cases.

Example of Test Scenario: User login verification.

Test Cases

The Test Case is a specific and detailed instruction set for executing the test. It describes each step in the test, inputs, input conditions, and expected results for executing the test. Test Cases are more detailed and used to verify individual aspects of the software`s functionality.

The Characteristics of Test Cases

Level of detail: It describes, how to execute the test. It includes detailed instructions for testing.
Specificity: It focuses on a specific aspect or function.
Structuredness: Test cases contain clearly defined prerequisites, steps, input data, and expected results.

The test cases are an important part of systematic and repeatable testing. They provide clearly instructions and can be followed by different testers.

Example of Test Case:

Name: Verify that the user signs in with the correct credentials.
Prerequisites/input conditions: Loading Sign-in page (https://beta.qlog.tech/en/login)
Steps:
1. Load Sign In page
2. Fill in the user name into the user name input (user@qlog.tech).
3. Fill in the password into the password input (Passw0rd).
4. Submit Sign In action by clicking the "Sign In" button.
Data for testing:
- User name: user@qlog.tech
- Password: Passw0rd
Expected Result:
- The main page will be displayed to the user. Users can see a list of projects and available subscriptions.

Summary

Understanding the difference between test scenarios and test cases is crucial for effective planning and execution of software testing, whether it is manual or automated. Test scenarios offer a general framework and guidance for testing, while test cases ensure systematic and thorough verification of specific functionalities.
