5 steps to effectively implement Agile for API Testing?

In
a growing data driven world the seamless functioning of software applications
is not just important but critical as well. The successful functioning of a
software program(s) can help an enterprise in many ways. These can be related
to brand building, achieving customer satisfaction, drawing potential customers,
and improving the ROI. And yes, not to forget, ensuring the compatibility of
the application across devices, browsers, operating systems, platforms and
networks.
Today,
a software program or application can have security ramifications as well given
the growing threat of cybercrime. So, if an application gets compromised, it
can lead the business to fall foul of regulatory authorities, lose customer
trust and competitive edge, and the failure to meet ROI. To prevent these, a
rigorous Agile testing of software should be implemented. In this type of
testing, Agile testers check for
glitches in the application and send the code(s) back to the development team
for rewriting.
Even
though implementing Agile is arguably the best way to ensure the
robustness and seamless functioning of an application across platforms,
devices, and networks, it does not always include testing the API. This
is due to the fact that an APIautomation testing can be a daunting exercise given the complexity
involved. The complexity lies in understanding the connections and interactions
between applications, systems, databases, devices, frameworks, and networks.
What is an API?
The
Application Program Interface is a set of tools, processes and protocols that
communicate across programs, systems, databases and networks. Also, an API
helps to integrate different parts of an application to facilitate the latter’s
smooth functioning and performance in accordance with the stated business
objectives. An API is akin to a user interface that facilitates communication
between a human and a computer. In the absence of an API, various strands of an
application(s) will not be able to optimally function let alone meet the
desired objectives.
The
bottom line is that an API is the glue that holds a software application(s)
together. It helps the application to interact with the systems, devices,
databases, and networks to produce the desired outcome. The role of APIs has
become even more important today thanks to the proliferation of innovative and
result oriented software incorporating cutting edge technologies.
How critical is API testing?
As
mentioned above, the growing complexity of software applications in meeting the
challenges of a competitive business environment means they should be tested
preferably with Agile test automation.
Since APIs are the critical components of software applications, API testing has become important.
Their seamless functioning helps software applications to interact with each
other and perform to their optimum. This invariably leads to a superior
customer experience and realization of ROI. Testing of the APIs validates
the integration of various software components and dependencies to effectively
meet the performance metrics and security parameters.
Steps to effectively implement Agile for testing the APIs
#1 Test automation: The use of automation in an Agile testing strategy is critical as
the level of interaction between developers and testers in a sprint is high.
Manual testing will not be able to cope with the challenges of shorter
development cycles, which involve repetitive testing of a large number of
variables. The variables need to be tested for outcomes across frameworks,
operating systems, browsers, IDEs and networks. By using API test automation tools like Soap
UI, API Fortress etc., and calls can be sent to an API to check and log the
system’s response.
#2 Documentation: The API test requirements such as the purpose, functions and
features, integrations supported, and workflow should be documented. This helps
in better planning and implementation of the test.
#3 Define the test output parameters: The test outcomes can
range from checking the pass/fail status to calling another API(s) or
validating a data. In fact, there can be times when there is no discernible
output as well.
#4 Focus on smaller API functions: Instead of creating
bigger test cases given their complexity and uncertainty, it is better to focus
on the smaller ones. This is due to the fact that it is easier to write smaller
API test codes and check for their outcomes. These small API test cases can be
later clubbed together to save time.
#5 Security Testing: The Agile application
testing should include API security testing as well given its dire
ramifications. The test should be able to validate the authenticity of a user
by checking his or her credentials from the database with an API function.
Conclusion
The
testing of an API function through Agile methodology leads to a better
identification of glitches and proper quality validation. The test outcome has
a bearing on the seamless functioning of applications, which can lead to an
enhanced customer experience.
