		### setFlows(testFlow, type, testCredentials, cb)

		Updates the currently loaded flow. This function has the following arguments:

		* testFlow: (array of objects) Flow data to test a node. If you want to use flow data exported from Node-RED editor, export the flow to the clipboard and paste the content into your test scripts.
		* type: (string) Flow data to test a node. If you want to use flow data exported from Node-RED editor, export the flow to the clipboard and paste the content into your test scripts.
		* testCredentials: (object) Optional node credentials.
		* cb: (function) Function to call back when testFlows has been loaded (not required when called wih `await`)
