perfrunner-core

Perfrunner-core

This package was written to simplify performance testing for the web application. It supports:

• Network conditions - downloadThroughput, uploadThroughput, latency
• CPU throttling
• Browser caching and no caching
• Multiple runs against the same URL for better precision
• Chrome arguments
• Storing data between test runs
• Tracing in Chrome readable format for better investigation

Installation

npm i perfrunner-core -D

Usage example

import { profile } from 'perfrunner-core';

(async function () {
    const profilingResult = await profile({
        url: 'https://drag13.io',
        network: { downloadThroughput: 1000, uploadThroughput: 500, latency: 200 },
        output: './generated',
        runs: 5,
        throttlingRate: 4,
        timeout: 90000,
    });

    console.log(JSON.stringify(profilingResult));
});

Tracing

After testing, you can find traces in Chrome readable format inside the folder related to the test run. This might be helpful for additional investigation

Tests

npm test
