Project Lifecycle and Vortex OpenSplice

Requirements and Design

Design phase should focus on data modeling

Coding / Development

Tuner / Tester – the tools of choice during the initial development process

Implementation / Testing

Tester / Insight – Automated testing debugging improves reliability and robustness

Integration / Verification / Validation Tuner / Tester / Insight / RnR Manager – the Tester and Record and Replay manager simplify management of Complex test scenarios

Coding / Development

An example scenario (Incomplete code) Developer has implemented part of the required code

How do you unit test publishers / subscribers?

Use Tuner to create a complementary Reader / Writer

Coding / Development Ishapes app

Problem:

Publisher is complete

Subscriber is not

HOW DO WE TEST?

Solution:

Create a reader / writer in Tuner

Take / Read some samples

Verification of Publisher complete!

Scenario: QoS Mismatch (subscriber not seeing data) A publishers is sending data

A subscriber is not seeing the sample

How do we detect the problem?

Use Tester to explore possible issues

Using Tester’s Browser we can easily see the problem is a QoS Mismatch

Integration / Verification / Validation

Scenario: QoS Mismatch found We’ve found issue is a QoS mismatch

How can we quickly test without recompiling?

Use Tuners to modify QoS settings on a running application Tuner is a “White-box” tool

This means it can look inside running applications

Integration: QoS Mismatch

Three applications using Ownership Strength Ishapes1 is subscribing with Ownership exclusive

iShapes2 is publishing with strength of 10

Ishapes3 is publishing with strength of 20

How can we change the strength without recompiling? We use the tuner to get / set QoS on the running applications
