load-page-regression-test

This tool allows you check some performance values of your page. It uses puppeteer to opening the page and getting performance values from it.

Run

To run with config (see below):

load-page-regression-test --config path/to/config/file.json

or to run with default checkers' parameters:

load-page-regression-test https://github.com https://google.com

Config

Config file allows you specify URLs which should be check, override some values for checkers or disable some rules at all.

Config must have the following structure:

{
  "URL": {
    "rules": {
      "RULE-NAME": { // optional
        "value": NEW_VALUE_FOR_RULE, // to override checker's default parameter
        "enabled": false, // to disable checker for this page - by default all checkers are enabled
      }
    }
  },
}

Example of simple config:

{
  "https://github.com": {
    "rules": {
      "requests-count": {
        "value": 100
      }
    }
  },
  "https://www.google.com": {
    "rules": {
      "requests-count": {
        "enabled": false
      }
    }
  },
  "https://translate.google.com": {}
}
