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.

3. 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.

4. ● 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.

5. ● 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.
