How Agile Testing Principles Deliver Better Quality Software
The Agile methodology has
come to represent a swift and flexible approach to developing and delivering
error-free applications to the market. It has allowed developers to decrease
production times and streamline the development process so that the product is
in alignment with customer needs. In agile, cross-functional teams, especially
development and testing, work collaboratively in short iterations. Agile
encompasses several practices that vary from traditional software development
techniques. The key focus areas of agile methodology in software development are:
·
More customer-centric instead of being
process-centric.
·
Focus on delivering working software rather than detailed
documentation.
·
Be adaptive to change rather than relying on a
fixed plan.
Unlike traditional software development where team
members stick to their respective areas, agile is more about continuous
integration and testing. In other words, cross-functional teams collaborate to
add (and test) new features as they work. Since the software development
lifecycle in agile is different, teams ought to follow a different approach
towards agile testing.
What is agile testing and how is it different?
In the waterfall method of development, testing is
usually implemented at the end of the software development lifecycle. This
approach is risky as any error identified within the document needs to be
corrected at the last minute. Importantly, many corrections may require
developers to strip the software modules from one another to find the root
cause, which can be both time and cost-intensive. Testing is a part of the
development process in the agile testing methodology, and it is done in an
integrated and incremental manner. This enables continuous integration and
constant feedback from all stakeholders through short iterative cycles known as
sprints.
In an agile
testing approach, bugs are identified and fixed quickly, thereby improving
the quality of the deployed product. The approach includes planning meetings
during the initial sprint where the scope of development and testing in each
iteration is defined. And to make the iterations more efficient, agile
test automation is implemented.
Testing principles for agile testing methodology
Agile teams need to release new products or
features to the market in short development cycles. The entire SDLC is
underpinned by delivering a superior customer experience. The challenge of agile application testing is to
test the quality of each software module quickly and comprehensively. In an agile
testing approach, testers are integrated into the SDLC alongside
development by creating a continuous feedback loop. This leads to quality being
‘baked’ right into the code. The various testing principles supporting the agile
testing methodology are as follows:
#1 Continuous testing: Agile
testing experts perform continuous testing of software developed in
collaboration with developers in short iterative cycles known as sprints. This
is done to ensure the software application remains qualitatively superior at
each phase of development.
#2 Continuous feedback: The sprint
incorporates a continuous feedback loop where agile testers pass on any
test-related information to the development team immediately. This results in
quick mitigation of glitches.
#3 Collaborative effort: The
testing process is not a standalone process but a collaborative one where
developers, testers, and business analysts form part of the sprint. Even the client
or product owner is kept in the loop.
#4 Superior quality: Since bugs
and vulnerabilities are quickly detected and mitigated in sprints, the
individual software modules and the overall software application developed are
of superior quality.
#5 Less focus on documentation:
Agile testing experts focus on changing customer
needs and market dynamics instead of documenting requirements.
#6 Test driven: Unlike in
traditional testing methods, agile testers evaluate the software application
before deployment rather than waiting for any adverse customer feedback later.
#7 Regression cycles: Developers
update their software products by adding features frequently. This can create
regressions in the existing features, which are addressed by leveraging agile test automation in a fast-paced
environment.
#8 Compatibility testing: Since the
software application is to be viewed and executed on devices of various types,
screen resolutions, and configurations, testers need to rely on performing
automation tests across browsers and devices.
#9 Face-to-face interaction: During
sprint planning, direct, face-to-face communication with all stakeholders -
product owners, business analysts, developers, and testers – is done. This
ensures everyone is on the same page regarding the sprint goals and scope.
#10 Value to the customer: Both
developers and testers ensure the software product meets customer requirements
through usability testing. Here, feedback from both internal and external
customers is taken into consideration before actual deployment.
Conclusion
Agile
testing improves the quality of the product and enables
organizations to release software applications in shorter cycles. By
identifying and mitigating errors early in the development process, the agile testing framework ensures
meeting business objectives such as quick deployment, customer satisfaction and
retention, and improved revenues.
