PHPUnit causes undefined method error when --coverage-text (using pcov)

Question

I'm trying to get coverage with pcov & PHPUnit for my Laravel project on docker.

I get an error PHP Fatal error: Uncaught Error: Call to undefined method Illuminate\Container\Container::basePath() when I add --coverage-text. No error occurs without --coverage-text.

What should I do to fix this?

• Case with --coverage-text

# php -d pcov.enabled=1 ./vendor/bin/phpunit --coverage-text tests/Unit/path/to/my/file
PHPUnit 8.5.9 by Sebastian Bergmann and contributors.
