I built a free HTML test reporter for Playwright, Jest, Vitest and Cucumber.js that automatically captures API calls, screenshots and retries

Описание и применение

Создан бесплатный HTML‑отчёт для Playwright, Jest, Vitest и Cucumber.js, автоматически собирающий API‑запросы, скриншоты и информацию о повторных попытках, без изменения тестов.

Задача

When a test fails in CI, developers need to know the API response, screen state, retry behavior, and flakiness, but default reports only show assertions and stack traces.

Результат

The reporter automatically captures API calls, screenshots, logs, and retry data across multiple frameworks, producing a single HTML file that can be attached to tickets or shared as a CI artifact.

Рабочий процесс

• Install the appropriate @acereports package via npm
• Add the reporter configuration to the test framework config (e.g., playwright.config.ts, jest.config.js, vitest.config.ts, cucumber.js)
• Run tests normally; the reporter writes TestResults/AceReport_.html
• Open the HTML file to view API calls, screenshots, logs, and retry details
• Optionally add custom logs or screenshots using the ace API in test code

Доказательства

When a test fails in CI, I usually end up asking the same questions: What did the API actually return? What was on the screen when it failed? Did it fail on the first try, or only on the retry? Is this test flaky, or did something really break?

Источник

It already existed for .NET, Java and Python, and it’s now on npm for TypeScript/JavaScript.

Every API call: method, URL, request and response bodies, status and duration. It hooks Node’s http/https and the global fetch, so it covers axios, fetch, got, supertest, node-fetch, ky and Playwright’s request fixture.

Источник

A screenshot on failure, taken before teardown closes the browser.

Источник

Retries and flaky tests: every attempt is its own tab with its own logs, error, API calls and screenshots.

Источник

One HTML file, no server: attach it to a ticket, email it, or keep it as a CI artifact.

Источник

Install with npm i -D @acereports/playwright (or /jest, /vitest, /cucumber). Run your tests as usual, and the report is written to TestResults/AceReport_.html.

Источник

Limitations: It doesn’t see HTTP/2 calls made with the http2 module, or gRPC. Vitest is supported in Node mode only, not browser mode. Requires Node 18+, Playwright 1.40+, Jest 29+, Vitest 3+ and Cucumber.js 10+.
