Testing & Evaluation

What type of testing involves using any number between 1 and 19?

• Normal Testing

• Extreme Testing

• Exceptional Testing

• Boundary Testing

Answer explanation

Normal Testing involves using any number within a specified range, such as 1 to 19. This contrasts with other types like Boundary Testing, which focuses on the limits of ranges.

Which numbers are used in extreme testing according to the picture?

• 1 and 19

• 0 and 20

• 5 and 15

• 10 and 30

Answer explanation

The correct choice is 0 and 20, as these numbers represent the boundaries used in extreme testing. They help ensure that the system behaves correctly at the limits of its input range.

What does exceptional testing involve according to the picture?

• Numbers between 1 and 19

• Numbers 0 and 20

• BGFST

• The number 5

Answer explanation

Exceptional testing involves the sequence 'BGFST', which is the correct choice. The other options do not relate to the concept of exceptional testing as depicted in the picture.

What is a common example of a syntax error in coding?

• Dividing a number by zero

• Missing a letter or character

• Using an undefined variable

• Infinite loop

Answer explanation

A common syntax error occurs when a programmer misses a letter or character in the code, leading to incorrect parsing. This is distinct from runtime errors like dividing by zero or using an undefined variable.

What is another name for an execution error?

• Syntax error

• Logical error

• Runtime error

• Compilation error

Answer explanation

A runtime error occurs during program execution, often due to illegal operations or resource issues. This distinguishes it from syntax, logical, and compilation errors, which arise at different stages of code processing.

What happens when an execution error occurs?

• The program runs successfully

• The program crashes

• The program compiles without issues

• The program outputs incorrect results

Answer explanation

When an execution error occurs, it typically leads to the program crashing. This means the program cannot continue running due to the error, unlike compilation issues or incorrect outputs.

Which of the following is a widely used example of a runtime error?

• Forgetting a semicolon

• Using a wrong variable name

• Asking a program to divide by 0

• Incorrect loop condition

Answer explanation

Asking a program to divide by 0 is a classic runtime error because it causes the program to crash or throw an exception during execution. The other options are typically syntax or logical errors that are caught at compile time.

What is a logic error in programming?

• An error that prevents the code from compiling

• An error in the logic of the code, such as using < instead of > or AND instead of OR

• An error that causes the program to crash

• An error that occurs due to incorrect syntax

Answer explanation

A logic error occurs when the code runs without crashing but produces incorrect results due to flawed logic, like using < instead of >. This distinguishes it from syntax errors or runtime errors.

What is the form of quality assurance carried out by a software development company after software has been implemented, tested, and documented?

• Evaluation

• Implementation

• Development

• Testing

Answer explanation

After software implementation, the quality assurance process involves Evaluation, which assesses the software's performance and compliance with requirements. This ensures that the software meets quality standards post-deployment.

When is software deemed fit for purpose?

• When it is developed quickly

• When it meets the requirements determined at the analysis phase

• When it is cost-effective

• When it has the latest features

Answer explanation

Software is deemed fit for purpose when it meets the requirements determined at the analysis phase, ensuring it fulfills the intended needs and functions effectively.
