You don't need this - There is a default PHPUnit feature --order-by=random about phpunit-randomizer HOT 2 CLOSED

Nice! Can you send me a link to the PHPUnit docs where this is documented? Thanks!

from phpunit-randomizer.

Can't find the docs, but this is the release: https://github.com/sebastianbergmann/phpunit/blob/master/ChangeLog-7.3.md#730---2018-08-03

It also supports fixing the seed by doing this:

SEED=$(head -200 /dev/urandom | cksum | cut -f1 -d " ")
echo "Running tests with seed $SEED"
vendor/bin/phpunit --order-by=random --random-order-seed=$SEED
