Quality

• What is the root of qualitative testing?
• Qualitative has a root of quality
• Quality is defined as
• Subjectively, something might be good because it
  is useful, because it is beautiful, or simply
  because it exists. Determining or finding Quality
  therefore involves an understanding of use,
  beauty and existence - what is useful, what is
  beautiful and what exists. The usefulness aspect
  is reflected in the common usage of quality.
