An intro to Context Driven Testing
Critical Thinking Skills
Session Based / Exploratory Testing
That's a wrap...
What is Critical Thinking?
The Mary had a little Lamb heuristic
Critical Thinking is thinking about thinking with the aim of
not getting fooled.
- Volatile: regards a matter that is subject to sudden or extreme change. (The assumption
may be invalidated unexpectedly.)
- Unsustainable: may be hard to maintain over a long period of time. (The assumption
must be stable.)
- Blind: regards a matter about which you have no evidence whatsoever.
Did you just see what I saw?
How do we do Critical Thinking?
Use of Safety Words
- Aim is to avoid false confidence
- Verbal Heuristics
CDT/RST - what does it all mean?
Context Driven Testing is all in the mind.
It also develops the idea of testing as a specialist practice.
"Anyone can test!"
- people with no clue
Heuristic Test Strategy Model
(and Mind Maps)
Session Based Testing
Exploratory is not unstructured
Sessions can help structure your testing - four guidelines
1. Each session should have a charter/objective
2. Time box your test sessions and focus
3. Keep test session reports & screen recordings
4. Review your test sessions
Most of all though, make it work for you and for the situation.
Investigation vs. checking
Use your experience
It's about balance:
You will always need to team exploratory/investigative testing with traditional "checking"
Sometimes the checking may be fully automatable
Both approaches provide different kinds of value, a different set of information
Adam's ideal world scenario...
A heuristic is a fallible method of solving a problem or making a decision.
You apply a heuristic as you would postulate a theory
All models and oracles are heuristic - they are fallible and representative
The HTSM is a way of thinking about your testing strategy.
You can apply the heuristics to
your software to evaluate it.
Oh hey... mind maps!

How can I apply it?
