Non-functional testing is critical in software development to assess aspects such as performance, usability, and reliability, which directly affect user experience. It aims to identify bugs that could cost the U.S. economy $60 billion annually, emphasizing the need for effective testing methods to mitigate risks. Various testing techniques are utilized, including black box, white box, and alpha/beta testing, to ensure software meets customer requirements before deployment.

1. What are the advantages
of non-functional testing

2.  Software testing is a study conducted to provide information about
products or services to interested parties. It provides a view of the
private sector to enable people to understand the risks associated
with having to use it.
 Thus, warning and preventing potential loss if the system is used
correctly. Different users require different software. For example, a
banker will need some banking supportive program and a designer
will need designing application and a player of computer games will
need gaming supportive system .
 So when you're starting a business or part of the software, then you
should be able to judge whether this is acceptable or not to end
customers.
 According to a recent study conducted by NIST, bugs in the software
digs a hole worth 60,000,000,000 dollars annually to the economy of
the United States. Better management of software testing and
quality assurance can avoid such risks from bugs coming in it.

3.  There are different forms of software bugs such as errors in
programming, compatibility with previous versions later,
compatible hardware etc to review the code and perform
under these test conditions.
 Some testing methods used for this drive:
 1) black box,
 2) white box,
 3) Grey box,
 4) Integration tests for regression testing,
 5) Testing for confirmation
 6) Acceptance testing,
 7) Non- functional testing
 8) Destructive testing.

4.  There are several ways to perform software examining. It can
perform basic program modules or units each. It is called unit
testing and can be done in an operating system while placing it in a
test case and is known as system testing.
 Nowadays, the group of independent testing services follow this
process before the software is deposited with the customers.
 Before the product is shipped to a customer, an additional test
called alpha and beta testing is done.
 Alpha testing involves examining the final version of the product
and then beta testing is done by distributing products to select
audience outside the test group feedback.

5.  Software testing used to highlight the flaws in the code, to test its
compatibility with other hardware/ software to predict customer
response to the product.
 The test program’s limit has not confirmed in all circumstances. You
can try a limited trial condition to check the failure of the product.
 Many certification programs bring professional software tester.
However, no certification examines the concept of such a tester in
this field.
 Certification alone cannot ensure the ability of examiners if many
believe that the authors are not yet ready to show it though it
promises for a gorgeous career for all the people who want to do it.
