  • 🐘 /bulktest: A PHP command-line tool that can submit a bulk set of tests, gather the results, and aggregate analyses.
  • 🐍 /batchtool: A Python tool that can submit a bulk set of tests and gather the results.

If your instance runs, but you’re having issues configuring agents, navigate to http://{your_instance’s_ip}/install to check for a valid configuration.

WebPageTest uses PHPUnit for unit tests. To set up and run the unit tests:

1. Install Composer
2. Run composer install
3. Run composer test

There are separate lines of development under different licenses (pull requests accepted to either):

• The master branch where most active development occurs has the Polyform Shield 1.0.0 license
• The apache branch has the more permissive Apache 2.0 license

WebPageTest uses PSR12 coding conventions for PHP linting and formatting. For JavaScript and CSS formatting we use Prettier with its default configuration. Additionally we use Stylelint for CSS linting.

Before you send a pull request please make sure to run: composer lint && composer format.

Alternatively you can run

• composer lint:php && composer format:php if you only touched PHP code, or
• composer lint:css && composer format:prettier if you only touched CSS or JavaScript code

If you use VSCode you might find it helpful to install Prettier and PHP Intelephence plugins and use these in your "settings.json":

{
  "[php]": {
    "editor.tabSize": 4
  },

  // uncomment to reformat on every file save
  //"editor.formatOnSave": true,

  "phpcs.standard": "PSR12",

  "files.trimTrailingWhitespace": true,

  "files.eol": "\n",

  "files.associations": {
    "*.inc": "php"
  }
}
