Dataflow Testing Quiz

What does dataflow testing primarily focus on?

• Code indentation

• User experience

• Flow of data within a program

• Hardware testing

In dataflow testing, what does it mean when a variable is "killed"?

• It is multiplied.

• It is deleted or becomes invalid.

• It is initialized.

• It is used in a calculation.

Which of the following is an example of using a variable in dataflow testing?

• Initializing it

• Defining it

• Using it in a calculation

• Leaving it undefined

Which type of machine processes instructions based on data availability?

• Von Neumann machine

• Dataflow machine

• Turing machine

• Arithmetic machine

In a train schedule analogy for dataflow testing, what does "killed" represent?

• When the train reaches its destination

• When the train is delayed

• When the train starts

• When the train schedule is canceled

What is a "data object state" in dataflow testing?

• A variable's data type

• A variable's status (e.g., defined, used, or killed)

• A program's execution state

• A variable's memory address

What type of error occurs when a variable is used before being defined?

• Syntax error

• Dataflow anomaly

• Memory leak

• Runtime exception

What does "static detection" involve in dataflow testing?

• Debugging during runtime

• Analyzing code without running it

• Monitoring program crashes

• Running all unit tests simultaneously

Which component in Von Neumann architecture performs calculations?

• Control unit

• Arithmetic Logic Unit (ALU)

• Memory unit

• Input/output unit

What is a "data flowgraph"?

• A representation of variable states

• A flowchart for debugging

• A diagram showing how data flows in a program

• A graphical representation of errors
