Curie Documentation

Curie is a scenario-execution engine for virtualized infrastructure tests. It is the backbone for scenarios implemented in the Nutanix X-Ray product.

Scenarios are the combination of a virtualized infrastructure (VMs), workloads that run on those VMs, and a sequence of events. These events or steps are operations like: VM power ops, clones, workload start/stop, node power ops, etc. Scenarios are described at the highest level in YAML and are cross platform and abstracted from underlying APIs, meaning that any supported virtual infrastructure should be able to perform the events and scenario authors need not know about specific APIs to perform the events. Example scenarios can be found at this location

To learn more about writing scenarios in YAML, requirements, and the API, check out the following sections:
