Define test cases, test scenarios, and test scripts.

People who are getting ready for an online Software Testing Certification Course certainly hear the words "test cases," "test scenarios," and "test scripts" a lot. 

Although they may seem similar at first glance, each term has a distinct role in the field of software testing.

You need to know the differences between them not only to pass interviews but also to become a good QA professional. 

In this column, we will provide detailed explanations of each concept, offer examples, and address the most common questions and answers that applicants have regarding software testing.

What does a test scenario look like?

A test scenario is a broad outline of what needs to be tested. Think of it as the "what" of testing, where you focus on the feature or functionality that has to be checked.

• For example, "Check that the app's login works with valid credentials."
• It doesn't go into a lot of information, but it does provide a direction for testing.

What makes test scenarios so important?

• They ensure comprehensive coverage of all the application's features.
• They allow testers and other stakeholders to identify the regions under testing.
• They serve as a foundation for composing comprehensive test cases.

What is a case for testing?

A test case is a full, step-by-step guide on how to test a certain feature. It tells you "how" to test.

For example:

• Test Case Number: TC_001
• Scenario: the ability to log in
• Step 1: Go to the page where you can log in.
• Step 2: Type in a username that works.
• Step 3: Type in a password that works.
• Step 4: Click the button that says "Log In."

Expected Result: The user should be sent to the dashboard.

Important Parts of Test Cases

• Test Case ID Preconditions.
• Steps for the Test.
• Data for the test: Expected Result, Actual Result.

What is the need for test cases?

• To verify that the functionality works as planned.
• To be used as a record for future reference.
• The purpose is to establish a standard for scripts that automate tasks.

What does a test script do?

A test script is a piece of code or an automated instruction that runs a test case automatically. These scripts use programming or scripting languages, which is different from manual test cases.

• For example, you could use Selenium with Java to automate the login process.
• Test scripts save time when you have to run the same test more than once.

What makes test scripts so important?

• They make regression testing work better.
• They cut down on mistakes people make when doing the same thing over and over.
• They make tests more accurate in big projects.

Q1: What is the difference between test cases and test scenarios?

Answer: Test scenarios are more general and tell you what to test. Test cases are more specific and tell you how to test. 

Scenarios are like chapters, and test cases are like the paragraphs that explain how to do each step in those chapters.

Q2. Can test scripts take the role of test cases?

Answer: No. Usually, test scripts come from test cases. Writing test scripts would be unclear and lack direction if you didn't first define test cases.

Q3. Do we need test scenarios if we already have test cases?

Yes, that's the answer. Test scenarios provide you with a complete picture and ensure you don't miss any features. They serve as checkpoints to verify that coverage is correct.

Q4. Why do trainers in an online Software Testing Certification Course put so much emphasis on these three words?

Answer: Because they each test a separate part of the system:

• Test scenarios set the limits.
• Test cases show the steps.
• Test scripts are what make automation possible.

Q5. In what fields are test scripts used a lot?

Answer: Test scripts are very important for industries that need to do a lot of testing over and over again, such as e-commerce, banking, healthcare, and travel apps.

Q6. How do you decide which test scenarios to run first?

Answer: Prioritization relies on how the feature affects the business.

• How often is it used?
• The decision is based on the risk and difficulty of the function.

Q7. How do you ensure that test scenarios cover all the features?

Answer: By looking at the requirement documentation and user stories, and talking to stakeholders to fill in any gaps.

Q8. How do you turn test cases into test scripts in automated testing?

Answer: Testers first identify test cases that are high-priority and repeatable. Then they use technologies like Selenium, JUnit, or TestNG to automate them.

Q9: What role do test scripts play in Agile testing?

Answer: In Agile, where short iterations are prevalent, test scripts speed up regression processes and keep quality high throughout sprints.

Q10. What problems do testers have when they write test scripts?

Answer: Some of the most common problems are keeping scripts up to date, making sure tools work with each other, dealing with changing data, and needing to be good with technology.

Think about how you would test the login feature of a financial app.

• Test Scenario: Verify that you can log in with both valid and invalid credentials.
• Test Case: Steps include inputting a username and password, clicking "submit," and verifying the results for valid and invalid data.
• Test Script: An automated Selenium script runs several sets of test data to check that the login works.

This structured method makes sure that the testing procedure is both accurate and efficient.
