Download as PPTX, PDF0 likes37 views
The document discusses exploratory testing and inattentional blindness, emphasizing that while humans can overlook obvious details due to focus, computers are inherently 'inattentional blind' by design. It highlights the need for a dynamic set of tests that adapt to new possibilities and risks, akin to investigative processes in crime scene analysis where judgment is crucial. The importance of context in testing is also mentioned, illustrating that testing operates within constraints influenced by various stakeholders' interests and objectives.

- 3. Inattentional Blindness We pay attention to some things and therefore we do NOT pay attention to others Even events that “should be” obvious will be missed if we are attending to other things. Computers focus only on what they are programmed to look at: They are inattentionally blind by design! Content from Cen Kaner, Exploratory Testing @ QUEST 2008
- 4. What we need … Is a constantly evolving set of tests That exercise the software in new ways (new combinations of features and data) So that we get our choice of Broader coverage of the infinite space of possibilities Adapting as we recognize new classes of possibilities And sharper focus On risks or issues that we decide are of critical interest today Content from Cen Kaner, Exploratory Testing @ QUEST 2008
- 5. Testing is like CSI MANY tools, procedures, sources of evidence. • Tools and procedures don't define an investigation or its goals. • There is too much evidence to test, tools are often expensive, so investigators must exercise judgment. • The investigator must pick what to study, and how in order to reveal how, in order to reveal the most needed information.

- 7. Context Testing is always done within a context We test in the face of harsh constraints • Complete testing is impossible • Project schedules and budget are finite Testing might be done before, during or after a release Improvement of product or process might or might not be an objective of testing We test on behalf of stakeholders • Project manager, marketing manager, programmer, competitor, attorney – Which stakeholder(s) this time? • What information are they interested in? • What risks do they want to mitigate?
