Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

5. Introduction
• Digital systems are everywhere i.e. microprocessors
– Laptops, automobiles, mobile phones etc.
• These systems are very complex
– Billions of transistors, many components
• How are they designed? – ABSTRACTION
– Hiding details when not important

Digital vs. Analog Quantities
• Electronic circuits can be divided into two broad
categories
– 1. Analog Quantities
• Quantities with continuous values (most things that can be measured
quantitatively).
• e.g. air temperature changes over a continuous range of values;
temperature does not change from, say 70 to 71 instantaneously; it
takes on all infinite values in between: see graph
• Other examples: time, pressure, distance and sound

12. IS 151 Digital Circuitry 12
Digital vs. Analog Quantities
• The sampled values represent the temperature at
discrete points over a 24-hour period.
– i.e. 1,2,3 etc, which are discrete
• The analog quantity (temperature) have been converted
to a form that can be represented in digital form
13. IS 151 Digital Circuitry 13
Digital vs. Analog Quantities
– 2. Digital Quantities
• Quantities with discrete values
• Data can be processed and transmitted more efficiently and
reliably
• Useful in data storage: e.g. music when converted to digital
can be stored more compactly (e.g.mp3 music)
15. Advantages of Digital
• Immune to noise, distortion
• Can be duplicated easily
– Copying a cd vs copying a tape
IS 151 Digital Circuitry 15

Data Representation Basics
• Computing systems are complex devices, dealing with a variety of
information categories
• Computing systems store, present, and modify:
– Text
– Audio
– Images and graphics
– Video
– Etc.
17. IS 151 Digital Circuitry 17
Binary Representation
• Why binary representation (as opposed to decimal or octal, etc..)?
– Cost
• Devices that store and manage digital data are far less expensive and complex for
binary representation.
– Reliability
• More reliable when they have to represent one out of only two possible values.
– Handling
• Electronic signals are easier to maintain if they carry only binary data.
18. IS 151 Digital Circuitry 18
Binary Representation
• One bit can either be 0 or 1.
– Therefore, one bit can represent only two things – 1 and 0
• To represent more than two things, multiple bits are needed
– Two bits can represent four things because there are four combinations of
0 and 1 that can be made from two bits: 00, 01, 10, 11.
• In general, n bits can represent 2n things because there are 2n
combinations of 0 and 1 that can be made from n bits.
19. IS 151 Digital Circuitry 19
Data Formats - How to Interpret Data
• Internal representation must be appropriate
– E.g. Images, sound, and video: have to be digitized
• Images – need detailed description of the data, how color is
represented at each data point
• Sound – need sampling, digitizing
• Video – need sampling and digitizing in space and time (because of
motion)
20. IS 151 Digital Circuitry 20
Codes and Characters
• The problem:
– Representing text strings, such as
Hello, world in a computer
• Each character is coded as a byte (8 bits)
– including blank spaces, commas, full stops
• Most common coding system is ASCII
• To represent alphanumeric characters – 8 bits per character
– 7-bit code : 27 = 128 codes are used (128 characters can be represented)
– 8th bit is unused (or used for a parity bit)
• Two types of codes:
– 95 are “Graphic” codes (visible)
• Alphabetic, numeric and punctuation characters
– 33 are “Control” codes (control features)
• Shift, delete, enter, etc.
21. IS 151 Digital Circuitry 21
Binary Digits
– In digital electronics, there are only two possible states and can
be represented by
• two different voltage levels: HIGH and LOW
• current levels: OPEN and CLOSED
• lamps: ON and OFF
– The two states are called codes, and combinations of the two
are used to represent numbers, symbols, alphabetic characters
and other types of information
22. IS 151 Digital Circuitry 22
Binary Digits
– The two-state number system is called binary, and the two
digits in the binary system are 0 and 1.
• A binary digit is called a bit (binary digit).
– In digital circuits, two voltage levels are used to represent the
two bits
• 1 – represented by a high voltage level (HIGH)
• 0 – represented by a low voltage level (LOW)
– POSITIVE LOGIC – will be used throughout!
– C.f. NEGATIVE logic:, 1 – LOW, 0 – HIGH
23. IS 151 Digital Circuitry 23
Logic Levels
– Logic levels are voltages used to represent a 1 and a 0.
– One voltage level represents a HIGH and one voltage level
represents a LOW.
– Practically, a HIGH or a LOW can be any voltage between a
specified minimum value and a specified maximum.
24. IS 151 Digital Circuitry 24
Logic Levels
• Diagram: Logic level ranges (page 5)
• From the figure, VH(max) and VH(min) represent the maximum and minimum HIGH voltage
values, respectively
• VL(max) and VL(min) represent the maximum and minimum LOW voltage values,
respectively.
• The range of voltages between VL(max) and VH(min) is a range of uncertainty; a voltage in
the range of uncertainty can appear as either a HIGH or a LOW.
HIGH (1)
LOW (0)
Uncertain
VH(max)
VH(min)
VL(max)
VL(min)
25. IS 151 Digital Circuitry 25
Logic Levels
• Examples:
– The high values of a certain digital circuit may range from 2 V
to 5 V and the LOW values from 0 V to 0.8 V.
– If a voltage of 3.5 is applied, the circuit will accept it as a HIGH
(or binary 1); a voltage of 0.5 V will be accepted as a LOW
(binary 0); a voltage of 1 V will be uncertain
