Techniques are described for providing clients with access to events occurring during execution of defined workflows, such as under the control of a event monitoring service that is available to multiple subscribers, such as over one or more public networks. A configurable workflow service may automatically create events when a defined workflow executes, and, provide the events to the event monitoring service, which may respond to the generated events by taking various actions, such as providing event notifications, initiating workflow instances, etc.

Event-based composition model for workflow systems

A test document associated with a workflow definition is obtained, the test document including an input for an action of the workflow definition and an expected state for the workflow definition based on the input. The input is delivered for the action of a workflow instance, the workflow instance being an instance of the workflow definition executed by a workflow engine, and the action determined based upon a present state of the workflow instance. A next state of the workflow instance is obtained, where the next state is determined by the workflow engine based upon the present state, the action and the input. The next state of the workflow instance is compared to the expected state of the test document.
