func TestTLog(t *testing.T) {
t.Parallel()

- For your local dev, create a
Dockerfile
that is based on your production image and simply installxdebug
into it. Exemple:
FROM php:5
RUN yes | pecl install xdebug \
&& echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" > /usr/local/etc/php/conf.d/xdebug.ini \
