When running unit tests, xdebug will slow things down quite a bit. Most of the time we run tests we don’t need xdebug because we are not doing code coverage, or actually debugging. Here is how I quickly toggle xdebug on and off as needed from the command line.
I create two shell scripts called xon.sh and xoff.sh, and I just run whichever I need to set xdebug on or off.
xon.sh
#!/bin/zsh sed -i '' 's/;zend_extension="xdebug.so"/zend_extension="xdebug.so"/g' /usr/local/etc/php/7.4/php.ini
xoff.sh
#!/bin/zsh sed -i '' 's/zend_extension="xdebug.so"/;zend_extension="xdebug.so"/g' /usr/local/etc/php/7.4/php.ini
Of course, the syntax will likely be different for your system, but if you have xdebug installed, and want to make your unit tests run faster, this will help.
