[tacman]

I'm confused. Why do I want to use simple-phpunit and not phpunit?

I realize that installing

  composer require --dev symfony/test-pack

works. The Symfonycasts article on creating a reusable bundle references simple-phpunit, but maybe that's outdated.

I cannot reproduce. The steps above work for me.

Here's my output from yesterday when I posted this. However, today the exact same 3 lines from above work after deleting the directory and re-installing. Maybe something with the symlink?

I had the same problem. I solved it with this command ./vendor/bin/simple-phpunit --generate-configuration
