The WordPress PHP Coding Standards describe a consistent PHP coding style for all WordPress projects. This image allows for quick testing of your project to find any standards violations. It runs the WordPress Coding Standards standard in PHP_CodeSniffer and reports any warnings or errors that are found.
To run the tests, change into the directory for your project and run the following:
docker run -ti --rm -v $(pwd):/project chrisjean/wp-php-standards
