Seven Fundamentals of Testing

• Testing is always an important part of every
  discussion related to IT projects. There is a lot
  of content available online about what it is and
  how it is done. But in this blog, we are going to
  talk about the fundamentals of testing which have
  been gathered from about half a decade of
  experience. These fundamentals offer directions
  that are common for all types of testing.

The Fundamentals -

• The outcome of testing is the recognition of
  defects. It can prove that issues are there, but
  it can not show us that there are no issues. The
  software cannot be proved to be correct through
  testing even if there are no issues found.
  Testing does reduce the chances of undetected
  issues left in the software.
• Testing all the combinations of inputs and
  requirements is not attainable except in minor
  cases. Instead of trying to test all the
  combinations, testing should be focused on
  priorities, risk analysis, and techniques.
• Testing performed in the early stages of the
  software development life cycle saves time and
  money. Static and dynamic testing should be
  initiated as early as possible to find defects
  beforehand. Starting testing early benefits by
  decreasing costly changes.

• During testing before release, usually, a small
  number of modules comprise most of the bugs
  detected, responsible for most operational
  failures. The defect clusters predicted and the
  ones actually observed in the test or operation
  provide valuable input for risk analysis used to
  focus the testing efforts.
• New issues cannot be found by repeating the same
  tests over and over again. The present tests and
  test data can be changed and new tests can be
  written in order to find new defects. It is also
  called the pesticide paradox as the same tests
  get less effective just like the same pesticide
  stops killing the insects after a while. The
  pesticide paradox proves beneficial in cases like
  automated regression testing where it provides
  comparatively fewer regression defects.

• Testing is performed in different ways in
  different contexts. For example, a social media
  app is tested differently than an e-commerce
  shopping website and a sequential lifecycle
  project is tested in a way different from an
  agile project.
• Absence of errors is a misapprehension. There
  is a misconception that testers can execute all
  the possible tests and find all the issues, but
  fundamentals 1 and 2 show us that it is
  impossible. It is a mistake to believe that only
  finding and fixing a huge number of issues can
  ensure the success of a system.
