There are continuing debates whether QA in software
testing is redundant or not. Often automated testing is considered to be the
panacea for all QA problems. Many development teams often argue that they do
very well without QA engineers. Companies employ this strategy but without giving
any open credit to it for obvious reasons, but some of them even brag about it.
We are not among those who vouch for redundant
roles. We do not argue for eliminating the QA role, rather to go with the
evolution.
Agreed, that some software companies in Dubai
due to their scale, domain or context having a full time QA testing engineer
might be unnecessary. But these is an exception rather than the norm.
Developers and especially automated tests cannot supplant QA engineers. Also,
there are more benefits in differentiating development and QA roles. Here are
some of them:
Diverging mindset: Developers write tests to
prove the correctness of their code. Testers- to find the areas of failure.
There are critical differences in the mentality of
developers and testers. Developers’ hold their code closer to their heart and
know them inside out. Hence it is difficult for them to be impartial about it.
This the reason why developers test cases are often limited.
Programmers already have in their mind how the
software should perform and what they need to achieve and therefore stick to a
familiar scenario while
software testing in UAE . This leads to building
a perfectly accurate but at time error prone in nonstandard situations (missing
edge cases) fragment of code.
On the other hand, testing engineers, are not
attached to the code they test. They test out different creative scenarios of
using the software, just like many future users, and seek bugs that stay
outside the developers reach.
Generally, testers understand business premised
better and follow requirements more precisely, which is essential for
delivering software that meets business needs.
All this doesn’t mean that one is better than the
other. Both are excellent and is needed, as true superpower comes from the
collaboration between the testers and developers.
Sharing of Responsibility
While programmers are generally responsible for a
specific feature, system, microservice, or simply a fragment of code, testing
engineers are accountable for the product as a whole. They ensure that tests are actual and new
bugs or fragilities do not appear after modifications (to different segments of
the software! By separate development teams!) have been applied.
A good example here is the role of performing
end-to end testing of a product based on microservices spread among different
development teams. Having a QA tester from a software testing company in Dubai devoted to such complicated tasks that needs the coordination of
different teams is crucial.
Not Every Type of Testing Can Be Automated or Done
by Developers
Although there is a huge fan base for automation,
let us be honest with ourselves-all tests cannot be done by automation some
still do require human cognitive ability and common sense.
A fine example would be exploratory testing.
Testers need to apply their creativity, experience, analytical skills and be
familiar with the logic behind the software to find all possible issues.
Sometimes it is insight or instinct that help them accomplish their task.
Another
possible example is black box testing, which is not possible without a pair of
eyeballs.
