Diadrom Dolphin - CI Reference case: T1 and Diadrom CI

• Diadrom has helped with setting up the VCC FLR CI

chain

• Pre-study and implementation

• Outcome:

• Every commit tested

• Release build time reduced from 3 days manual labour

to 1h automatic build

Diadrom Dolphin and CI

• Command line interface

• Configure test execution in GUI

• Export in json format

• Sync configuration between platforms
