Complexity…. Made Simple!

• Multiple layers of

technology

• Multiple vendor

platforms

• Complex

transactions

• Complex

dependencies

• Multiple

stakeholders

Integration Testing



Blockers of early end to end testing…

“The test environment

refresh takes 3 weeks!!”

“Some of the services we need are

still unavailable!”

“Can we begin some testing

before everything is available?”

“It is too expensive to setup a live message

feed for test!”

“We’re still waiting for them to deploy!”

No need to modify

application code

Variety of tools to enable

creation of virtual service

eg recording

Frees projects from

external constraints eg

databases, app servers

Simplifies management of

Stub execution

Enables traceability over

where stubs are running

Provides audit of who ran

stubs and when

Enables simple versioning

of stubs

Removes delays caused

by late delivery of external

interfaces

Speeds up development of

stubs for testers and

developers

Stubs can be reused and

embellished to support

different test cycles

Allows control over

datasets being used

across an environment

Enables erroneous data to

be played back into

systems

Removes the need for

costly 3rd party interface

leasing

Let’s developers get on

with developing code not

stubs

Puts testers back in control

and removes dependency

on other teams

Easily simulate “+1”

changes to interfaces and

environments

Enables multi interface,

complex and stateful

simulation easily

Limits risk and lowers

integration issues when

going into production



Rational and HP Integration

Link requirements to test assets

Execute tests from test

management dashboard

Leverage existing reporting

structures

Raise defects directly into defect

tracking system; RTC, HP QC, JIRA

etc

Embed deeplinks into defects



Continuous Delivery

Execute test assets in headless mode

– Regression test new code quickly

– Nightly test cycles

– Build/Deploy/Test/Report

Virtualise

Integrate into new or existing process

– Command line execution

– ANT task integration with Jenkins, CruiseControl, Bamboo, etc

– Native integrations RTC, RQM, HP QC etc

Rational Integration Tester reports served into a web browser (via RTCP)



The future of testing: IBM Rational solutions

IBM Rational Test Workbench

–Enable functional, performance and integration

testing throughout your project lifecycle.

–With a scriptless, wizard-driven test authoring

environment and support for more than 70

technologies and protocols,

IBM Rational Performance Test Server

–Save time and effort by reusing your functional

integration tests for performance testing

–Combine your tests to model real-world scenarios

and assess the impact of load on your integrated

infrastructure.

IBM Rational Test Virtualization Server

–Model real system behavior to eliminate test

dependencies and simulate production,

–Accelerate testing and reduce the setup and

infrastructure costs of traditional testing environments.
