Introduction

• Software development is an elongated process. It
  has to pass through a number of verticals before
  getting finally launched in the market. As the
  owner of the application, it is essential to
  examine each and every attribute that includes
  functionality, performance, security, usability,
  accessibility and so on. All these shape and
  determine quality and acceptability of a product.
  Rigorous QA has now become significant due to
  increase in the expectation as well as demand of
  the end users. Ignoring a single aspect of
  testing can bring detrimental impact on success
  of a product because each depends on others.
• In order to compete in the global market, ability
  to function on a multitude of smart devices as
  well as platforms like Windows, MAC, e-readers
  and others is necessary. This calls for a
  strategy known as mobile testing in the IT world.
  The increasing usage of mobile devices have sky
  rocketed the demand of mobile testers. Companies
  have realized that success of their native, web
  or hybrid application doesnt rely only on one
  platform rather it must work on others too and
  without any discrepancies. Hence, both manual and
  automated testing is implemented to launch a
  flexible application.

What is Functional Testing?

• If the product fails to stand up to the existing
  market standard, it must be checked immediately
  because there are other apps and software ready
  to capture attention of the users. So, functional
  testing is implemented to enhance the potency and
  scope of the product. This QA process analyzes
  the software and studies whether it is working on
  a specific set of functionalities, according to
  the pre-defined specifications. On identifying
  any issue, the developers need to work again with
  the motive to release quality product.
• If the user experiences an ineffective and
  frustrating user interface, they will never use
  the product, even if the underlying code is
  well-scripted. Therefore, it is advised to
  perform functional testing at the user interface
  level. It can reveal a number of deficiencies
  that may not be apparent while conducting a
  review on the source code. As a tester, it is
  crucial to prioritize usability of the
  application first and then examine the
  complexities of the application's internal
  workings.
• Functional testing scrutinizes various commands
  and executable scripts, process integration and
  it also determines how the software will react in
  different configurations. It has a wide scope,
  helping enterprises to launch an error-free
  product. The testing can be done both manually
  and automatically. It can be done as a part of a
  core test pass as well as a regression test
  effort, or it can be scripted or exploratory.

Challenges of Functional Testing

• The need of functional testing has reached a new
  height with the increasing complexity of todays
  software products. The competitive pressures and
  high costs software have made it necessary to
  launch application with high-quality. But issues
  like shrinking development and deployment
  schedules, limited resources of skilled engineers
  are turning out to be some of the significant
  challenges.

Approach to Handle Challenges

• However, having an organized approach while
  rendering out testing services makes challenges
  less vulnerable. Some organizations practice
  framework based methodology, which comprises of
  the right mix of automation tools and native
  processes. This can reduce excessive time that is
  required to run a testing cycle as well as cut
  down the amount of effort spent in testing.
• Moreover, as a testing organization it is
  necessary to have a team of experts who are
  cross-trained and exposed to various areas of
  functional testing. The intention will be to
  ensure a cost-effective test cycle to improve
  quality of the product. Testers get the
  flexibility to analyze existing scripts on
  multiple browsers and operating systems that help
  in performing rigorous compatibility check.
  Proper implementation of QA methodology can
  drastically reduce the risks of application
  failures.

Functional Testing - Over the Ages

• The importance of functional testing cannot be
  overlooked and it remained the core of testing
  process for ages. Previously, this was given more
  emphasis than non-functional test areas. The
  pre-defined system or functional specifications
  were the base for the testers, who looked more
  into the functional verification ensuring that
  the application is built according to the defined
  specifications. However, in the last few years,
  the technological evolutions have played a part
  in bringing transformation in the sphere of
  testing. Currently, the user specification is
  higher and to accommodate the changing user
  needs, the system has to function in a robust
  manner. More emphasis is given on system
  validation that saves time and effort in the
  verification test cycle. The non-functional test
  areas, such as performance, security and
  usability, are given equal importance because the
  product has to function across a range of devices
  and platforms.
• As far as the future of functional testing is
  concerned, its importance will continue to grow
  because more and more enterprises are integrating
  Test Driven Development (TDD). The productivity
  of the testing team will no longer be affected as
  functional testing gives them the opportunity to
  carry on products validation and verification
  without getting blocked by any dependencies from
  other aspects. The product companies, on the
  other hand, want to make end users experience
  very rich as well as simple. Therefore,
  maintaining a quality control becomes essential
  that in-turn makes functional testing an
  unavoidable vertical in the long run.
