Selecting and using suitable test data

• What is the primary purpose of test data in programming?

  To test program functionality
• The goal of using test data is to ensure the program behaves as expected under only normal conditions.

  False
• Boundary data is used to test the program's ability to handle data at its limits
• Steps for developing a test data strategy:

  1️⃣ Define normal data

  2️⃣ Define boundary data

  3️⃣ Define erroneous data
• Reviewing past issues or user feedback can help anticipate potential problem areas when generating test data.


  True
• What is the primary characteristic of normal data in a test data set?

  Expected to handle correctly
• Normal data is defined as data that the program is expected to handle correctly
• What type of data should trigger error handling in a program?

  Erroneous data
• Match the type of test data with its definition:

  Normal data ↔️ Expected to handle correctly

  Boundary data ↔️ Limits of program handling

  Erroneous data ↔️ Should handle gracefully
• What is an example of normal data for a program that processes transaction amounts?

  Typical transaction amounts
• What is an example of erroneous data for a program that processes ages?

  Negative values
• What is one technique for generating effective test data?

  Analyzing program requirements
• Automated tools can be used to ensure consistency and coverage when generating test data.
• What are the three main types of test data used to create effective test data sets?

  Normal, boundary, erroneous data
• Boundary data refers to data at the limits of the program's expected range.


  True
• Match the type of test data with its example:

  Normal data ↔️ Typical transaction amounts

  Boundary data ↔️ Maximum allowed values

  Erroneous data ↔️ Non-numeric input
• What are the three main types of test data?

  Normal, boundary, erroneous
• Erroneous data is designed to test the program's ability to handle unexpected input
• Automating test data generation ensures consistency and reduces the risk of human error
• What does including a variety of test data types ensure about a program?

  Overall robustness
• The goal of using a variety of test data is to ensure the program behaves as expected under different conditions
• Normal data is expected to cause error handling in a program.

  False
• What is the purpose of boundary data in a test data strategy?

  Tests behavior at limits
• Boundary data includes empty fields as examples of data at the limits of the program's expected range.

  False
• Match the type of test data with its definition in program validation:

  Valid data ↔️ Typical inputs the program should handle successfully

  Invalid data ↔️ Inputs that should trigger error messages

  Boundary data ↔️ Values at the limits of the expected range
