Tester's Musings

A Theory of testing:  Definition of terms and concepts   basic concepts:  'Test Phase Space': The space containing all events and all data that are involved during Testing  'data points' -- these are the data within the Test Phase Space: they are divided into 2 categories:   input_data[aka inputs]  -- these are the data sets a tester inputs into a system  and output_data[aka outputs]   -- these are the data sets generated by the system under test  A Result -- is the behaviour that produces the outputs  STR (Steps To Replicate) -- is the manner of introducing the inputs into the system points connected together are called 'co-systemic' extraneous points -- are points that don't belong to the same line / branch / system A 'super_system' -- is different systems working together as a finished software product a 'system' -- is a group of branches connected to each other  a 'branch' -- is a test_path/s connected to ano...

    "The combination of not quite sure the right thing and not knowing for certain what the code was going to do - but evaluating as it happens, to me that is exploring" -- exactly same with my own personal observation. that's why being clumsy sometimes is very helpful, because that clumsy data set will become part of the test input and the results are as fascinating / insightful as what one sees in the Large Haldron Collider 😇 💡 https://www.linkedin.com/posts/agw-59661220b_softwaredevelopment-softwaretesting-activity-7305868821058265090-JGjp?utm_source=social_share_send&utm_medium=member_desktop_web&rcm=ACoAADVOWcIBc7VFWTKgh6Qof566qxbgu2eqJDQ

  "Testers are not just gatekeepers." --- they are scientists, mathematicians, analysts, with their own colours, who walk the plank on a daily basis  https://www.linkedin.com/posts/agw-59661220b_softwaretesting-softwareengineering-quality-activity-7305870725913948161-O6Lr?utm_source=social_share_send&utm_medium=member_desktop_web&rcm=ACoAADVOWcIBc7VFWTKgh6Qof566qxbgu2eqJDQ

  if the ISTQB (or any other Tester Certifying institution) can produce superstar 'testers' -- like this or that 'scientist' did something brilliant out of Cambridge, Yale, or Oxford, what does that say? well, for one, it would add 'brilliance and prestige' to the institution, but in hindsight it's not the institution -- but the *people* (in our scenario: *the actual testers*) that add the brilliance, the sparkle, the shine of skill. Riding on a name (or certificate), without observable proof of effectivity in the field (textbook certifications matter little), is more like resting on laurels taken from a tree, than earning them through challenge. https://www.linkedin.com/posts/agw-59661220b_how-to-scare-a-tester-part-2-activity-7305875698978631680-CjT-?utm_source=social_share_send&utm_medium=member_desktop_web&rcm=ACoAADVOWcIBc7VFWTKgh6Qof566qxbgu2eqJDQ
