Dummy Mode

Cylc 8 supports three run modes:

  • Live (default) - run tasks as normal.
  • Simulation - simulate tasks but don’t actually run them (good for testing).
  • Dummy - run blank local tasks instead of the real ones.

To use these, use the --mode option when starting a workflow e.g:

cylc vip --mode=dummy

Dummy mode essentially strips out the [runtime] section of your workflow turning each task into platform = localhost and script = true.

For most testing purposes simulation mode is more appropriate and will become more flexible in the future.

We’re not sure what use cases remain for “dummy mode”
