Selecting and using suitable test data

• Match the test data type with its description:

  Normal data ↔️ Typical input values

  Boundary data ↔️ Values at the edges

  Erroneous data ↔️ Values outside the range
• Boundary data refers to input values at the edges of the expected input range
• Steps for using selected test data effectively

  1️⃣ Create test cases

  2️⃣ Group test cases into test suites

  3️⃣ Execute test cases

  4️⃣ Record and analyze results
• Effective test suites minimize undiscovered errors by achieving high code coverage.


  True
• Erroneous data includes input values that are outside the expected input range.


  True
• There are two main types of test data: normal and boundary data.

  False
• What is the primary purpose of testing a program before its release?

  Identify and fix errors
• Boundary data is used to test input values at the edges of the expected range.


  True
• There are different types of test data that can be used, including normal, boundary, and erroneous
• Erroneous data includes input values that are outside the expected input range
• The purpose of testing is to ensure a program is robust and fit for purpose.


  True
• Which strategy for selecting test data involves using typical input values?

  Normal data
• Test suites aim for high code coverage
• What are typical input values that a program is expected to handle correctly called?

  Normal data
• What is the purpose of using a variety of test data types in software testing?

  Identify and fix errors
• What type of test data verifies basic program functionality with typical input values?

  Normal data
• What is the primary goal of selecting appropriate test data in software testing?

  Thorough testing
• What is a test case in software testing?

  Specific input and output
• Why is test data validation important in software testing?

  Identifies and fixes errors
• What is the purpose of normal data in testing?

  Verify basic functionality
• Why is it important to use a variety of test data in software testing?

  Ensure all inputs are handled
• What type of testing ensures that a program can handle unexpected or extreme scenarios?

  Erroneous data testing
• A diverse set of test data helps identify edge cases in a program.


  True
• What does a test case outline in software testing?

  Input values and expected outputs
• Boundary data refers to input values at the edges of the expected input range
• The purpose of testing is to identify and fix errors to ensure the program is robust and fit for purpose
• Boundary data is used to check how the program handles input values at the edges of the expected input range
• Match the test data type with its purpose:

  Normal data ↔️ Verifies basic functionality

  Boundary data ↔️ Checks how the program handles extremes

  Erroneous data ↔️ Verifies error handling
• A test suite is a group of related test cases used to comprehensively cover various program features and potential error scenarios
• Erroneous data verifies the program's error handling capabilities with input values outside the expected range.


  True
• If a program expects ages from 1 to 100, boundary data could be 1 and 100
• Code coverage measures the extent to which source code is executed during testing.
