WIP: feat: Add Playwright E2E test for API-backed UI interactions #4463
Conversation
|
I think the idea might have been to make requests to each of the public endpoints in the ComfyUI webserver and validate that the response matches the expected type. We have this schema which defines the spec for a lot of the webserver responses: https://github.com/Comfy-Org/ComfyUI_frontend/blob/1200c07fcd6e14a4c3a8734468bd6cf694c23205/src/schemas/apiSchema.ts, but our current tests don't validate that that schema is actually in-line with the current state of the server on ComfyUI master. Example: // tests/api-integration.spec.ts
import { test, expect } from '@playwright/test';
import {
GetUserDataResponse,
GetSystemStatsResponse,
GetQueueResponse
} from '../src/schemas/apiSchema';
test.describe('API Schema Validation', () => {
test('GET /queue returns valid schema', async ({ request }) => {
const response = await request.get('/queue');
expect(response.status()).toBe(200);
const data = await response.json();
// This will throw if validation fails
const validatedQueue = GetQueueResponse.parse(data);
expect(validatedQueue.queue_running).toBeDefined();
expect(validatedQueue.queue_pending).toBeDefined();
});
test('GET /system_stats returns valid schema', async ({ request }) => {
const response = await request.get('/system_stats');
expect(response.status()).toBe(200);
const data = await response.json();
const validatedStats = GetSystemStatsResponse.parse(data);
expect(validatedStats.system).toBeDefined();
expect(validatedStats.devices).toBeDefined();
});
}); |

Hi @aybanda please find my notes below (should echo what you received via email as well): PR Review SummaryStatus: 🔄 Changes Requested For the ContributorThank you for this E2E testing implementation. The code structure targets workflow CRUD operations using appropriate Playwright patterns. Your positive response to @christian-byrne's API validation suggestion is noted. However, there are critical compilation issues that must be addressed before we can proceed. Technical Summary

Hi @aybanda, thanks for this contribution. The API integration tests address issue #4402 as requested. Before Core Team ReviewThis PR includes significant test deletions (8,483 lines removed) alongside the new tests. Please add the following documentation to your PR description: 1. Test Deletion RationaleYou've deleted several test files entirely:
Please document:
Note: I found 0 occurrences of feature flag patterns in the codebase, which may support that deletion. 2. PR ScopeThis PR combines three distinct changes: adding API tests, deleting old tests, and refactoring fixtures. Please either:
3. Next StepsOnce this documentation is complete:
The API tests themselves appear functional. We need the test deletion context documented for future reference. Thanks for your work so far! |
- Ensure all tests pass and no critical functionality is broken
