Rails "test:system" Rake task doesn't run any tests

[chrisgibson]

I created a new Rails application (with v7.0.3.1) and generated a new system test.

With v2.0.11 of the tailwindcss-rails gem, bin/rails test:system prints the Tailwind CSS compilation output and exits (without running any tests).

If I downgrade to v2.0.10, it prints the Tailwind CSS compilation output and proceeds to run the tests.

I believe the use of exec (introduced in #181) has changed the behavior when multiple Rake tasks are involved as is the case when the test:prepare Rails Rake task is enhanced with tailwindcss:build. The process is exiting after the Tailwind CSS compilation.

@chrisgibson Yup, what you're describing makes sense and we shouldn't be using exec. I'll explore replacing it putting some tests in place to prevent regressions in the rake tasks.

Looks like a PR to address this has been opened at #189

Release v2.0.12 · rails/tailwindcss-rails addresses this.

Confirmed. Thanks @flavorjones!
