Abstract
Gartner published a recent study of best practices for producing higher quality software to
market faster, by shifting testing left in the SDLC, leveraging reusable isolation testing and
exploiting mocking services and service virtualization.
This session will explore how various solutions from CA Technologies were used to achieve
Gartner recommendations.

PYRAMID-SHAPED LAYERED APPROACH TO TESTING
Gartner – Layered Testing Strategy Finding

Gartner Recommendation
Use a layered, reuse
approach – execute tests
continuously
Focus less on GUI testing
and more on business
logic testing
Define and honor unit
test criteria
Educate developers on
unit test and dependency
injection coding patterns
Use mocking and service
virtualization
Use virtualized data
solutions to simulate real-
life data
> > >
> > >

Gartner Conclusion
Teams increase their ability to get quality products to market
more quickly when they focus on writing scripts that can be used
for unit, integration and performance testing. A layered testing
strategy helps teams exploit script reuse by reducing the need
for expensive and brittle GUI testing.
