Let's say you find an ideal development team that creates
the perfect app you order. How do you know it's not just a pretty picture, but
a perfect piece of engineering software that will give you a good profit? That
is why the practice of quality control, including software testing, were
created.
Quality control is an integral part of the software
development process, focused on fulfilling quality requirements. The purpose of
quality control is to find flaws and defects in software products and to
eliminate them before the final release. Testing is one of the most important
measures of quality control software. And as a customer, you have to
understand, how the testing guarantees perfect quality of your product.
Today most of the software development company employing
Agile development to produce new applications quickly and cost effectively. In
agile methods, software testing is integrated into the development process, the
developers and testers often compare notes and think beyond their designated
roles to ensure high quality products.
So how exactly do software testing work? Let's take a peek
behind the scenes of the testing procedures of Agile development processes.
STEP FOUR TESTING
Although testing is a continuous practice during the
development process, can be divided into four important steps. We'll go through
them one by one for you to understand how software testing works.
The initial analysis of Quality Requirements
Before starting construction, you will have a very important
meeting with your project manager and Quality Assurance (QA) specialists. Each
of the parties concerned must be 100% aware of the needs of the product so that
no problems will arise after construction is completed. initial requirements
analysis will allow QA specialists to form the initial test plan, including the
test specification.

ISO 9126 software quality characteristics split into six
categories. To meet all requirements of the standard, the software developed to
be functional, reliable, use, efficient, maintained and portable. Each of these
requirements must be tested. You should be able to check the test results
through a clear and concise documentation.
Testing in Iteration
agile development desired product split into a number of
iterations. Intermediate results of each iteration is a version of a product
with reduced functionality. This approach allows you to introduce changes to
the product requirements and received the results of a rapid transition every
step of the way. As mentioned earlier, Agile development tools, parallel
development and testing process.

Therefore, testing is done in each iteration to correct any
problems and does not transfer to the next iteration.
First, QA specialists to plan the testing process as a whole
and determine its specific: types of testing required and software environment,
the features to be tested and the testing criteria for each feature. Next, test
documentation is created. This can take the form of a checklist or test cases,
depending on the scope of the project and needs.

Once the initial phase is completed, the actual testing can
begin. According to the plan iterations, the examiner checks to find any
defects or problems. When the bug is fixed, it's time for regression testing.
It checks the quality of correction implemented and determine their negative
effects on other components of the application. iteration is complete after the
test results are analyzed, and the test report is compiled.
End Testing and Verification Before Release
When the developer is finished, it is time for testers to
roll up their sleeves and get down to work. In the final stage, you will not be
able to change your needs lots. All you have to do is wait for the testing to
be completed before the final release of your software.

Testers working full-time on checking and re-checking code,
finding and fixing bugs and polishing the finished product. This step is very
important and never miss because only now testers get their hands on the entire
functionality of the product and can test the final version. Do not try to rush
testing together, as a sloppy quality control can lead to a number of problems
of post-release.
Post-Release Maintenance and Support
In a world that is always changing, no application can last
forever without any updates. Each new version needs to be tested with the same
attention to detail as the first release. And even if you do not plan to launch
an upgraded version in the near future, it's a good idea to invest in some post-release
maintenance. There must have been some unexpected problems that require instant
fix. quality control and quality assurance measures are as important
post-release, because they are before the final launch.

PEOPLE BEHIND TESTING
Testing is typically assigned to a separate part of the team
to ensure that each test is completed to compliance with quality assurance
standards, strategies, and guidelines. Dedicated professionals have the
experience and methodological skills required to plan, analyze and perform all
kinds of necessary testing. Testers continue to improve methodologies and their
tools to meet varied demands of the market and to optimize existing techniques.

Most of the tests (about 80%) is automatic. They require
regular results with various repetitions in one or more iterations. test load
and other types of tests that are difficult to do manually is also automatic.
The test requires environmental testing and specialized software to ensure
solid results. The remaining 20% of the tests carried out manually to assess
the utility of the product, accessibility, and other characteristics.
Now you know how the testing helps ensure the high quality
of your software. But remember that testing is only one of the reactive part of
the management of quality control and quality assurance system. There are many
proactive measures focused on ensuring confidence that your quality
expectations will be met. But that's a story for another time.
