When contributing please run all tests before committing:

# Using Makefile (append ENV=local if you don't utilize docker)
make pre-commit-test

# Using composer (also uses "make" command internally, your OS may need a
# package like "build-essential")
composer make pre-commit-test

# Using ddev
ddev composer make pre-commit-test

You can use a helper script to set this up once in your project, so that these checks are performed before any Git commit:

# Using Makefile
make githooks

# Using composer
composer make githooks

# Using ddev
ddev composer make githooks

Those Git hooks will also check your commit message for line length.
