Generating Mock Data for Google Calendar

Create representative mock calendar events to test agent reasoning without altering live calendars.

Learning Objectives

Structure realistic meeting payloads with start/end times and attendee lists
Incorporate edge cases like overlapping events and missing locations
Load mock data into n8n Code nodes for offline testing

Generating Mock Data for Google Calendar

Before connecting production Google credentials, developing with mock data accelerates testing and eliminates unnecessary API roundtrips.

Mock Calendar Payload

Add a Code node named Mock Calendar Provider:

javascript

const today = new Date().toISOString().split('T')[0];

return [
  {
    json: {
      items: [
        {
          id: "evt_1",
          summary: "Q3 Product Architecture Review",
          start: { dateTime: `${today}T09:00:00Z` },
          end: { dateTime: `${today}T10:00:00Z` },
          attendees: ["ceo@company.com", "cto@company.com"],
          location: "Zoom Conference Room A",
          urgent: true
        },
        {
          id: "evt_2",
          summary: "Lunch with Angel Investors",
          start: { dateTime: `${today}T12:30:00Z` },
          end: { dateTime: `${today}T13:30:00Z` },
          attendees: ["partner@venturefirm.com"],
          location: "Bistro Central (Outdoor Terrace)",
          urgent: false
        },
        {
          id: "evt_3",
          summary: "Sprint Planning & Standup",
          start: { dateTime: `${today}T15:00:00Z` },
          end: { dateTime: `${today}T16:00:00Z` },
          attendees: ["engineering-team@company.com"],
          location: "Google Meet",
          urgent: false
        }
      ]
    }
  }
];

Notice the second meeting: an outdoor terrace lunch. When the agent checks weather later, it should cross-reference this outdoor location against storm forecasts!
