Lucidchart CI Integration

Overview

Configure CI pipelines that validate Lucidchart diagramming API integrations using a two-tier testing strategy. Unit tests mock the Lucidchart REST client to verify document creation, shape manipulation, and export logic without requiring OAuth2 credentials. Integration tests run on main-branch merges with a real OAuth2 token to confirm document CRUD, versioned API header handling, and export rendering against the live Lucidchart API. This separation keeps PR cycles fast while catching OAuth flow regressions and API version changes before they reach production.

Mock-Based Unit Tests

// tests/unit/document-service.test.ts
import { describe, it, expect, vi } from 'vitest';
import { createDiagram } from '../../src/services/document-service';
import * as lucidClient from '../../src/lib/lucid-client';

vi.mock('../../src/lib/lucid-client');

describe('DocumentService', () => {
  it('creates a flowchart document with initial shapes', async () => {
    vi.mocked(lucidClient.post).mockResolvedValue({
      documentId: 'doc-7742',
      title: 'CI Pipeline Diagram',
      pageCount: 1,
      editUrl: 'https://lucid.app/documents/edit/doc-7742',
    });

    const result = await createDiagram('CI Pipeline Diagram', 'flowchart');
    expect(result.documentId).toBe('doc-7742');
    expect(lucidClient.post).toHaveBeenCalledWith(
      '/documents',
      { title: 'CI Pipeline Diagram', template: 'flowchart' },
      { headers: { 'Lucid-Api-Version': '1' } }
    );
  });
});

Integration Tests

// tests/integration/document-export.test.ts
import { describe, it, expect } from 'vitest';
import { LucidClient } from '../../src/lib/lucid-client';

const canRun = process.env.LUCID_API_KEY && process.env.LUCID_CLIENT_SECRET;

describe.skipIf(!canRun)('Lucidchart Document Export (live API)', () => {
  const client = new LucidClient({
    apiKey: process.env.LUCID_API_KEY!,
    clientSecret: process.env.LUCID_CLIENT_SECRET!,
  });

  it('exports a document as PNG', async () => {
    const docs = await client.get('/documents', { limit: 1 });
    expect(docs.length).toBeGreaterThan(0);

    const exported = await client.get(`/documents/${docs[0].documentId}/export`, {
      format: 'png', page: 1,
    });
    expect(exported.contentType).toBe('image/png');
    expect(exported.data.length).toBeGreaterThan(0);
  });
});

CI Cost Management

// tests/helpers/api-budget.ts
let callCount = 0;
const MAX_CALLS_PER_RUN = 20; // Lucidchart API: OAuth token refresh + tight rate limits

export function trackApiCall(): void {
  callCount++;
  if (callCount > MAX_CALLS_PER_RUN) {
    throw new Error(
      `CI API budget exceeded: ${callCount}/${MAX_CALLS_PER_RUN} calls. ` +
      'Lucidchart enforces per-app rate limits — reduce export tests or batch requests.'
    );
  }
}

export function getCallCount(): number { return callCount; }
