In experience based techniques, people’s knowledge, skills and background are of prime importance to the test conditions and test cases.
- The experience of both technical and business people is required, as they bring different perspectives to the test analysis and design process. Because of the previous experience with similar systems, they may have an idea as what could go wrong, which is very useful for testing.
- Experience-based techniques go together with specification-based and structure-based techniques, and are also used when there is no specification, or if the specification is inadequate or out of date.
- This may be the only type of technique used for low-risk systems, but this approach may be particularly useful under extreme time pressure – in fact this is one of the factors leading to exploratory testing.
