Troubleshooting private instances

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.

Testing

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

Install Composer
Install apcu
Add the line apc.enable_cli='on' to your php.ini
Run composer install
Run composer test

Contributing

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

Code style

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

VSCode integration

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"
  }
}
