Consequences and Importance of Software Testing

What is the primary purpose of software testing?

• To identify the correctness, completeness, and quality of developed computer software.

• To ensure software is released quickly to end-users.

• To reduce the cost of software development.

• To increase the complexity of software systems.

What is the main intent of the activities conducted during software testing?

• To add new features to the software.

• To find errors in software before product release.

• To train end-users on software functionality.

• To design the software architecture.

In simple terms, what does software testing aim to achieve?

• To make the software system more complex.

• To ensure the software system is defect-free.

• To increase the software's processing speed.

• To develop new software applications.

Which historical event involved a software bug causing the death of 264 people?

• The malfunction of the Therac-25 machine.

• A failed military satellite launch.

• The China Airlines Airbus A300 crash.

• A major U.S. bank account error.

What are the potential consequences of software bugs?

• Only minor inconveniences for users.

• Increased software performance.

• Monetary loss or even loss of life.

• Faster software development cycles.

What was the outcome of the software bug in the Therac-25 radiation therapy machine in 1985?

• It caused a satellite launch failure.

• It led to 3 deaths and 3 critical injuries due to lethal radiation doses.

• It resulted in 264 airplane crash fatalities.

• It credited bank customers with incorrect amounts.

What was the financial impact of the software bug that caused a failed military satellite launch in April 1999?

• $920 million lost.

• $1.2 billion lost.

• $264 million lost.

• $25 million lost.

In May 1996, a software bug caused what issue for a major U.S. bank?

• It deleted customer accounts.

• It credited 823 customers with $920 million.

• It caused a system-wide shutdown.

• It prevented online transactions.

Why is software testing considered crucial in software development?

• It makes software development faster.

• It ensures software bugs are always harmless.

• It prevents software from becoming too complex.

• It helps avoid expensive or dangerous consequences of software bugs.

What does Paul Ehrlich's quote, "to err is human, but to really foul things up you need a Computer," imply about computers?

• Computers are inherently flawless.

• Human errors are more significant than computer errors.

• Computers have the potential to amplify errors to a much larger scale.

• Computers are only useful for simple tasks.
