Diadrom Dolphin
Diadrom Software
• Test automation tool for verification and
validation
• Diadrom Dolphin assist our customers in
automatically verifying critical software
within the automotive industry.
• Used for testing of communication,
diagnostic, SWDL, application testing
etc.
• Using Iron python for tests ->
can interface the most APIs

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
