Abstract
:
The
good thing about Service Oriented Architectures is the flexibility
it provides – it allows for a heterogeneous computing
environment where different services and service providers
can work on different technologies, loose coupling of components
that allow any application to make use of the capabilities
and ad-hoc integration of applications within and across organizations.
SOA helps IT deal better with complex architectures. However
from a tester’s perspective these are the same things
that make testing of Web services and SOA based applications
so much more complex.
Adding to this Services have no user interface. They typically
interact with applications using encoded XML messages through
various transport protocols.
Testing these Services through the applications using them
is usually ineffective and not comprehensive as they may be
used by several applications both within and outside the organization,
and in case of issues, tracking the defects to the source
is difficult as the issue could be with one of several layers:
the consumer or the provider application, the message content,
the message encryption or the transportation.
Further, testing of Non-Functional requirements is also critical.
One needs to test for Compliance to standards, Interoperability,
Security, Quality of service, and Performance of web
services.
