Test Scenario Vs Test Case

What is a Test Case?

Test cases are sets of actions that are executed to verify particular features or functionality of software applications. It consists of test data, steps, preconditions, and post conditions developed for specific test scenarios to demonstrate any requirement.
  • Test cases are mainly derived from test scenarios.

  • It helps in the exhaustive testing of software.

  • Test cases include test steps, data, and expected outcomes for testing.

  • These are low-level actions and require more time and resources for execution.

Purpose of Test Case

  • Verification of compliance: Test cases help verify compliance with guidelines and client needs.

  • Improved data flow coverage: Test cases help to improve control, logic, and data flow coverage.

  • Exposes flaws: Test cases help to uncover flaws and defects in the software.

  • Testing will be structured: The test engineer’s job will be more convenient, simple, and structured when test cases are developed.

  • Validates customer expectations: Test cases help to validate customer requirements and expectations.

  • Allows to simulate real user scenarios: Test cases help to simulate real end-user scenarios.

Example of Test Case

Below are some examples of test cases:
  1. Check the behavior of the system when an invalid user id and invalid password are entered.

  2. Check the system’s behavior when a valid user ID and valid password are entered.

  3. Check the behavior of the system when a valid user id and invalid password are entered.

  4. Check the behavior of the system when an invalid user id and valid password are entered.

  5. Check the system behavior when ‘Keep me signed in’ is selected.

Best Practices for Test Cases

  • Clear: Test cases should be clear, transparent, and easy to understand.

  • Avoid repetition: Design test cases to avoid repetition.

  • Never make assumptions: When writing test cases, it is considered a best practice to never make assumptions about the features of the software.

  • Easily distinguishable: Test cases must be designed so they are easily distinguishable.

  • Check all software requirements: Write test cases to check all software requirements mentioned in the specification document.

What is a Test Scenario?

A test scenario is a collective set of test cases that helps the testing team determine the positive and negative features of the project.
  • It provides a high-level description of what has to be tested.

  • It is defined as a linear statement.

  • It is a detailed document that covers end to end functionality of a software application.

  • It is a valuable exercise for saving time.

  • It is simple to maintain, as adding and modifying test cases is simple.

Purpose of Test Scenario

  • Verify complete functionality: Test scenarios help verify the software application’s full functionality under test.

  • The business process according to functional requirements: Test scenarios help ensure the business flows and processes meet the application’s operational requirements.

  • Organize workforce: Test scenarios help to determine testing work effort and create a proposal for the client, thus helping to organize the workforce.

  • Determine end-to-end critical applications: Test scenarios help determine end-to-end essential software applications.

Example of Test Scenario

  • Check the payment functionality.

  • Check the login functionality.

  • Check whether authentication works properly.

  • Check whether the demo works as expected.

  • Check the search functionality.

  • Check shopping cart functionality.

Best Practices for Test Scenario

  • Single-lined statements: Test scenarios should be single-lined statements stating what should be tested.

  • Simple description: The test scenario should be simple and easy to understand.

  • Reusable: It is considered a best practice to create reusable test scenarios.
