Hi @Joe_McFadden,
Welcome to Google Cloud Community!
The ability to pass parameters using the @ symbol in the Dialogflow CX Agent Simulator preview is a helpful feature for testing. However, the current implementation seems to only support passing a single parameter at a time using this method. There's no documented way to pass multiple parameters using the @ symbol in a single input field.
To pass multiple parameters during testing in the simulator preview, you will have to rely on other methods:
- Multiple Test Runs: The simplest way to test with multiple parameters is to run multiple test simulations, each with a different parameter set provided using the @ symbol. This is less efficient for comprehensive testing but straightforward to implement.
- Advanced Testing Methods (If Available): Check the Dialogflow CX documentation or release note for any advanced testing features or tools that might allow for the injection of multiple parameters. The preview version might provide a more extensive testing environment, which is not yet documented.
- External Tools/Scripting: You could potentially build a small script or utilize an external testing tool that creates and sends test requests to the Dialogflow CX agent, passing multiple parameters in each request. This method requires more development effort but offers more control and efficiency for testing.
Regarding your request to see the current state of input/output parameters to a Playbook during testing, that's a valid suggestion for improvement. The current simulator's lack of this feature makes comprehensive testing of parameter passing more difficult. About this missing feature would be very useful, consider submitting a feature request so that our Engineering Team can look into it.
