What is Acceptability Testing?

An acceptability test is one where a set of inputs is run through the System Under Test (SUT) and checked to make sure the correct outputs are produced.

What is a Bug?

  • An execution error
  • Incorrect output

What are the possible sources of bugs?

  1. The SUT
  2. The Acceptability Test
  3. The Specification
  4. The System in which the software is run

How do you find the source of a bug?

Check the possible sources of bugs in order.
  • SUT: syntax, logic, etc.
  • Acceptability Test: same as SUT plus the input set
  • Specification: Understanding of what the SUT is supposed to do
  • System: Unfixable, look for workarounds and ways to report the problem
