2.3.2 Testing

• What is the primary purpose of testing in software development?

  To find defects/problems so they can be fixed before the program is used.
• Why is it important to ensure that end results meet user requirements?

  To ensure that the software fulfills the needs and expectations of the users.
• What is the significance of ensuring calculations are done correctly in testing?

  It prevents incorrect outputs that could lead to user dissatisfaction or errors in functionality.
• How does testing contribute to user/customer confidence?

  By identifying and fixing issues before the software is released, it assures users of its reliability.
• What are the two main types of testing in software development?

  • Iterative Testing: Testing during development.
  • Final Testing: Testing after the majority of development has been completed.
• What is a logic error in programming?

  An error that results in incorrect output but does not crash the program.
• What is a syntax error?

  An error in the grammar of the program that prevents it from running.
• What types of test data are used in software testing?

  • Normal: Data the program expects.
  • Boundary: Data on the boundary of expected values.
  • Invalid: Data beyond the expected range.
  • Erroneous: Data the program does not expect.
• How would you categorize the test data of 25 kg for luggage in the OCR Airlines example?

  Boundary test to check borderline free baggage.
• What is the purpose of testing with 30 kg of luggage in the OCR Airlines example?

  To test normal values for paid luggage.
• What does testing with 50 kg of luggage aim to achieve in the OCR Airlines example?

  To test borderline disallowed luggage.
• Why is testing with 60 kg of luggage considered invalid in the OCR Airlines example?

  Because it exceeds the maximum allowed weight of 50 kg.
• What is the purpose of testing with non-numeric data like "Bananas" in the OCR Airlines example?

  To test that erroneous/non-numerical data is rejected.
• What does testing with -1 kg of luggage aim to achieve in the OCR Airlines example?

  To test that erroneous negative values are rejected.
