A specific elaboration of Test Phase-Space 1.2 : Systems Thinking






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 another test_path/s 
          • also known as a subsystem
        • a 'test_path' is the straight line between input and output 
          • every test_path is created by the Developer
          • and every test-path is run/executed by the Tester

Pyramid, Honeycomb, Feather Testing Models

How much time should be allotted to each level of test activity (unit test, integration test, system test, end-to-end test)? it varies; but definitely just enough to get the job done to an agreed level of Acceptance Credence.  A model that is not adaptable to the task at hand constricts development, and needlessly constricts the actors themselves(coder, tester) -- such that, either  (a) the team starts to get coerced to follow the model, sacrificing any innate efficiency; or  (b) the team ignores the model and  lets the nature of the task dictate the most efficient work flow.  The nature of the test_paths themselves would provide the impetus  to place  emphasis on either  (c)   integration tests (e.g. majority of the test_paths are integration subsystems); (d) a balance of unit tests and end-to-end tests (e.g. the product is simple, or a self-contained supersystem); or (e) a balance of unit, integration, and comprehensive systemic tests ...

The phenomenon of QA(quality advocacy) in Test-PhaseSpace

Image
  Quality Advocacy                      \___ 3rd tier/level --- designers,  coders                      \___ 2nd tier/level --- quality advocates                      \___ 1st   tier/level  --- grassroots testers  ================= definitions:  ================= ..Quality [ Q ] = the state of the product (high or low) at any given time (m).  ..QA [ Quality Advocacy ] = the monitoring/measuring of quality to know quality ; unless it is monitored/measured, quality [ Q ] cannot be known. Quality Advocacy extends to all 3 tiers/levels.  ..QA [ Quality Assurance ] =  working together  as a  Development Team (coders + testers + proj.mgr + designers + etc.) which will always deliver a specific level of quality. ..software tester = 1st level, grassroots interactor [someone...

do QA/Testers contribute any value to the Product's Quality?

Image
With all due respect, my take on the matter is:  a.  hypothetically,   if a teamA{devs+testers+designers} >> work together == resulting in a product{Quality = 0.95 good}  b. if same teamA{devs+designers} minus the {Testers} >> work together == resulting in a product{Q = 0.65 good} c. then it means the product{Q} suffers a {0.30 good} reduction without the {Testers}  d. so, mathematically, the Testers seem to contribute to the Product{Q} an exact value of "N"  assuming the Devs work on the findings of Testers e. if Devs don't work on the Testers' findings, then the testers still would've contributed their share to the product being built , but the negative impact of the Devs' under-contribution will adversely affect the overall Product{Q} -- making {Q} fall below agreed values.  f. The relationship of contributions from actors {designers,devs,testers} is apparently non-linear --otherwise things would've been so obvious, this wouldn't be...
