Agile Development

DevOps is…

A set of principles and values that

facilitate collaboration across

disciplines to…

1. Enable rapid evolution of

deployed business services

2. Reduce risk, decrease cost, and

improve quality across the

portfolio

DevOps Principles and Values

1. Collaborate across disciplines

2. Develop and test against a

production-like system

3. Deploy frequently using

repeatable and reliable

processes

4. Continuously monitor and

What is Service Simulation and Test Virtualization?

Test Virtualization enables to create “virtual services”:

oVirtual Services simulate the behavior of an entire application or system during testing

oVirtual Services can run on commodity

hardware, private cloud, public cloud

oEach developer, tester can easily have their

own test environment

oDeveloper and testers continue to use their

testing tools (Manual, Web performance, UI

test automation)

System dependencies are a key challenge in setting up test environments:

�Unavailable/inaccessible: Testing is constrained due to production schedules, security restrictions, contention between teams, or because they are still under development

�Costly 3rd party access fees: Developing or testing against Cloud-based or other shared services can result in costly usage fees

�Impractical hardware-based virtualization: Systems are either too difficult (mainframes) or remote (third-party services) to replicate via traditional hardware-based virtualization approaches

�Test Virtualization is an enabler for continuous Integration Testing

�Services, applications, systems are introduced into the continuous integration cycle in a prioritized, controlled fashion.

IBM Rational Test Virtualization Solution

IBM Rational Test Virtualization Solution for continuous integration and testing

• Avoid time spent installing and configuring software just to discover

basic build issues

• Smoke tests can be integrated as part of the continuous integration

process through deployment automation and test virtualization

• Smoke test results are made available to the entire team to shorten

resolution

end

service_name "httpd"

# If restarted/reloaded too quickly httpd has a habit of failing.

# This may happen with multiple recipes notifying apache to restart - like

# during the initial bootstrap.
