And auto fix test which will do nothing. File is unchanged.

Problem solved: The error indicates that I don't have installed the patch command, which PHPCBF uses to apply changes in one action.

docker/php-fpm/Dockerfile

FROM php:fpm

RUN apt-get update && \
apt-get install -y wget && \
apt-get install -y vim && \
apt-get install -y patch && \
wget https://squizlabs.github.io/PHP_CodeSniffer/phpcs.phar && \
wget https://squizlabs.github.io/PHP_CodeSniffer/phpcbf.phar

RUN chmod u+x *.phar

RUN mv phpcbf.phar /usr/local/bin/phpcbf
RUN mv phpcs.phar /usr/local/bin/phpcs

RUN phpcs --config-set default_standard PSR2

RUN apt-get remove -y wget
