Key phases of Fundamental Test Process according to ISTQB standard
Слайд 6European Headquarters – Lviv, Ukraine
Why testing is necessary
We should assume our
work contains mistakes
Слайд 8European Headquarters – Lviv, Ukraine
Why testing is necessary
Some of the problems
might be trivial, but others can be costly and damaging - with loss of money, time or business reputation - and even may result in injury or death
Слайд 9European Headquarters – Lviv, Ukraine
Why testing is necessary
Not all software systems
carry the same level of risk and not all problems have the same impact when they occur
Слайд 10European Headquarters – Lviv, Ukraine
Causes of software defects
Human action that produces
incorrect result
A flaw in a component or system that can cause the component or system to fail to perform its required function
Deviation from expected result
Слайд 11European Headquarters – Lviv, Ukraine
Cost of defect
The cost of finding and
fixing defects rises considerably across the life cycle
Слайд 12European Headquarters – Lviv, Ukraine
Testing and Quality
Testing helps us to measure
the quality of software in terms of:
the number of defects found,
the tests run,
and the system covered by the tests.

and the system covered by the tests.

Software Quality – ISTQB definition
Quality: the degree
to which a system, component, or process meets:
- specified requirements
- customer or user needs or expectations
- customer or user needs or expectations
Слайд 14European Headquarters – Lviv, Ukraine
Software Testing - ISTQB definition
Testing is the
process consisting of:
all lifecycle activities,
both static and dynamic,
concerned with planning, preparation and evaluation of software products and related work products
to determine that software products satisfies specified requirements,
to demonstrate that they are fit for purpose,
and to detect defects.

Quality assurance- ISTQB definition
Quality assurance: Part of
quality management focused on providing confidence that quality requirements will be fulfilled
Quality Management
Quality Control
Quality Assurance
Слайд 18European Headquarters – Lviv, Ukraine
Principle 1
If no defects are found, it
is not a proof of correctness
Слайд 19European Headquarters – Lviv, Ukraine
Principle 2
Exhaustive testing is impossible
Instead of exhaustive
testing, use risks and priorities to focus testing efforts
Слайд 20European Headquarters – Lviv, Ukraine
Principle 3
Early testing
Find defects early on when
they are cheap to find and fix
Слайд 21European Headquarters – Lviv, Ukraine
Principle 4
Defect clustering
Review defects and failures
in order to improve processes
Слайд 22European Headquarters – Lviv, Ukraine
Principle 5
Pesticide paradox
Updated or NEW test
cases potentially find more defects
Test cases need to be regularly revised, new and different tests need to be written
Слайд 23European Headquarters – Lviv, Ukraine
Principle 6
Testing is context dependent
The higher the
possibility of losses, the more we need to invest in testing
Слайд 24
European Headquarters – Lviv, Ukraine
Principle 7
Absence of errors fallacy
The fact that
no defects are outstanding is not a good reason to ship the software
Слайд 26Fundamental Test Process
Test planning and control
Test analysis and design
Test implementation and
execution
Evaluating exit criteria and reporting
Test closure activities
