Causes Of Software Defects

– Error: Human make a mistake in code. Development of a document specification.

– Defect: A problem caused by an error.

  • Fault: A failure of the system or component caused by a defect.
    Failure: Failures don’t only happen due to defects, but also environmental conditions, hardware problems, etc.

All defects start with a human error (for example a typo, misunderstanding, lack planning, capability, etc.) The tester’s job is to expose the defect by causing a failure before the software gets to production.
