Introduction
===============================================================================
Testing is:
- Measure quality
- Increase confidence
- Help assess risks

Challenges:
- Big domains(infinite)
- Never exhaustive
- When to stop

Activities:
- Generation
- Execution
- Organization

Quality
Functionality, Reliability, Usability, Efficiency, Mainainability, Portability

Types:
- {Non, }Functional, functions or properties
- Dimensionality
	- Accessibility(black, grey, white box)
	- Detail(system, integration, module, unit)
	- Characteristics(functional, reliability, usability etc.)


Black & White Box Testing
===============================================================================
Black box
- Partitioning
- Boundary value analysis
- Error quessing(exploratory testing)

White box
- Coverage
	- Path
	- Statement
	- Condition
	- (multiple=all combinations of) Decicion

Test Organization/TMap
===============================================================================
TMap: Test Management approach
planning->preparation->generation->execution->completion

v-model
test incomplete things with
- Driver: piece that simulates higher level system
- Stub: piece that simulates lowel level

[L]ife cycle
- Strategy/planning
	- Mission
	- Strategy
	- Approach
	- Plan
- Preparation
	- Study test
	- Specifications
	- Testability
	- System division
- Generation
	- Generation of cases:
		- purpose, start, input, expected output
	- Test infrastructure
	- Implementation
- Execution
	- phase testing
		- static
		- pre-test
		- full
	- execution
		- test
		- repair
		- retest
	- discriminate in error
		- implementation
		- specification
 		- test case
		- infrastructure
	- report
- Completion
	- Report
	- testware
	- evaluation

More Black & White Box Testing
===============================================================================
Decision table: combination of input parameters
Use case: test according to use cases
Other whitebox: function, call, jump, dataflow, objectcode, loop, race

Combinatorial Testing
===============================================================================
- Pairwise(triples, ...)
- MC/DC. Modified condition/decision
	Test only important, shown to independantly affect outcome

	Thus if we have a && b && c we test:
	0 1 1 and 1 1 1

Mutation Testing
===============================================================================
Make mutants, deliberate errors and see if the test catch it
Add mutant, if not caught extend tests otherwise throw away mutant

Quality and Reliability Challenges
===============================================================================
- Systems of systems pose a problem
- Integration is a problem
- Interface testing
- Because of continous delivery regression testing
