testing? do it the smart way
Word ‘interface’ literally translated means ‘a face of an interior’ or ‘inner face of the program or the computer’, or going further: ‘a device/program with a human face’. In the strict sense it is an ergonomic interface connecting the environment of a machine and a human.
A software tester fights with the various devils. Today we will present the examples of the four demons that sometimes possess testers.
One of them, which I have already mentioned once (vide: A devilish software tester), is Mephistopheles. It’s a dangerous devil who loves being the tester and mercilessly torments the programmer!
Today we want to tell you a story of the word ‘bug’, which in the software testers’ jargon means an error, a defect, malfunction.
In 1906 Vilfredo Pareto discovered the rule stating that in case of many events, roughly 80% of the effects come from 20% of the causes. Today, after more than 100 years, “Rule 80/20″ because it operates under that name, is still used to diagnose social, economic and many other phenomena, for example:
- 20 % of drivers cause 80 % of accidents
- 80% of sales come from 20% of clients
- we wear 20% of clothes for 80 % of the time
This rule has also use in software testing.
