The Evil Tester's Guide to Web Testing @ Lets Test 2013

Published on

This is a placeholder 'teaser' presentation for a conference presentation at Let's Test 2013.

Come back after 21st March to see the real presentation.

I'm uploading this now, so that I can get the slideshare url and add it into the presentation.

I assert that Tester's need technical skills when testing 'anything'. Since I primarily test web applications, I will describe my technical view of Web Testing. In this session I will describe some of the tools that I use when testing, not because technical web testing revolves around tools, but because the technical testing thinking process leads to the finding and utilisation of tools. Tools are the draw, the quick win for attendees. But thought processes sit at the core of this talk. They lead to tool augmentation, to exploring the built in capabilities of the browsers, and to the skills we need to test technically. I will talk a little around theory, and, dangerously for a live session, I will provide a demonstration of tool augmented technical testing.

  3. 3. Technical Testing @EvilTester http://unow.be/at/letstest2013
  4. 4. What is Technical Testing? To You? ● How does the phrase make you feel? ● To you as a manager? ● To you as a tester? ● Can you identify with it? @EvilTester http://unow.be/at/letstest2013
  5. 5. What is Technical Testing? To Me? ● A reminder to keep "going deeper" ● It means "Tool Augmentation" ● How I describe what I do @EvilTester http://unow.be/at/letstest2013
  6. 6. A reminder to keep going deeper MORIM - Model through Observation, Reflection, Interrogation and Manipulation ● Model == what I think I currently understand ● Observations can corroborate or invalidate my model ● Reflect to find gaps and lack of depth and derive intent ● Interrogate - focused observation with intent ● Manipulation - hypothesis exploration @EvilTester http://unow.be/at/letstest2013
  7. 7. It means "Tool Augmentation" ● Tools to passively observe, maintain history of observations ● Tools to alert on specific conditions ● Tools to observe the unobserved, and interrogate the inaccessible ● Tools to help me model and reflect ● Tools to help me manipulate ● ... etc. Never tools to control. Tools to augment. @EvilTester http://unow.be/at/letstest2013
  8. 8. How I describe what I do ● ● ● ● Not a definition A description of my current approaches I try get as deep and technical as I can I need to keep learning so that I can understand the technology @EvilTester http://unow.be/at/letstest2013
  9. 9. Go beyond the surface structure ● Transformational Grammar ○ Surface & Deep Structure ● Questions operate as tools to investigate Surface to Deep mapping in people ● Bug? ○ Surface != Deep ○ Surface1 != Surface2 @EvilTester http://unow.be/at/letstest2013
  10. 10. Transformational Grammar ● Terminology originated with Chomsky ● Multiple surface structures ● Single Deep structure ● Deep structure ○ filtered, biased, distorted ■ Surface Structure NB: I'm reinterpreting this. Abusing it for my own purpose- to model Technical Testing @EvilTester http://unow.be/at/letstest2013
  11. 11. Questions operate as tools to investigate Surface to Deep mapping in people "Login doesn't work" ● ● ● ● How Specifically? How do you know? Ever? ... etc. We ask the system questions. @EvilTester http://unow.be/at/letstest2013
  12. 12. Some ways we notice bugs? ● Surface != Deep When we can't transform from our Deep Structure to the observed Surface Structure ● Surface1 != Surface2 When we spot different surface structures than we would expect from our transformations Surface == Model, Deep == Model, Model != Reality @EvilTester http://unow.be/at/letstest2013
  13. 13. How to do Technical testing ? TM ● Identify tools to work with System Surface Structures ● Questioning Systems at different surface levels ● Learning System Structure Technology ● Modelling System Surface Structures @EvilTester http://unow.be/at/letstest2013
  14. 14. Technical Web Testing @EvilTester http://unow.be/at/letstest2013
  15. 15. Technical Web Testing ● Understand and model the Project context ○ scope of testing, aims of testing, stakeholders, etc. ● Understand and model the System context ○ ○ ○ ○ the web context the application context the deployment context the usage context ● For each identify ○ Technical Risks ○ Test Ideas http://unow.be/at/letstest2013
  16. 16. Technicalities for Web Testing ● Understand and model the System context ○ ○ ○ ○ the web context the application context the deployment context the usage context ● For each identify ○ How can we observe it? ○ How can we interrogate it? ○ How can we manipulate it? ● ● ● @EvilTester Summary, Log, etc. Details & Different views Change & Amend http://unow.be/at/letstest2013
  17. 17. Web Context: A Browser View @EvilTester http://unow.be/at/letstest2013

  23. 23. "All together now" - a tool augmented group exploration demo ● Using only out of the box browser functionality. ● When exploring a web app ● What do we get out of the box to observe, manipulate, interrogate? ● What can't we do? ● What tools might let us do it? ● What does the tool functionality suggest for us? @EvilTester http://unow.be/at/letstest2013
  24. 24. Summary ● Technical Testing works with multiple models of the System ● Model for: ○ ○ ○ ○ Understanding Risk Test Ideas Tooling ideas ● Tool Augmentation ○ Observe ○ Interrogate ○ Manipulate @EvilTester http://unow.be/at/letstest2013
