Playwright-first API mock recorder/replayer (Atticus).

Quick start

Install (dev):

npm install --save-dev atticus-mock-service

Add to Playwright fixtures (example):

import { test as base } from '@playwright/test';
import { MockService } from 'atticus-mock-service';
import path from 'path';

export const test = base.extend({
  page: async ({ page }, use) => {
    const service = new MockService({
      mockDir: path.resolve('atticus-mocks'),
      recordMode: 'auto',
      autoApprove: true
    });
    await service.attachToPage(page);
    await use(page);
  }
});
export { expect } from '@playwright/test';

Modes:

• record — always hit real endpoints and save responses
• replay — only use saved responses; fail if missing
• auto — replay if present; otherwise record

Notes:

• If you see TLS errors for route.fetch(), set NODE_EXTRA_CA_CERTS to a CA file you trust and set ignoreHTTPSErrors: true in Playwright config.

Contributing and publishing:

• repo contains ci workflow that runs lint/build/test on PRs.
