Rails 6 when executing teaspoon for javascript testcases getting Module#parent` has been renamed to `module_parent`

Question

Getting the below error when executing the testcases using teaspoon gem for javascript testcases. I am not sure why stylesheets folder is considered while executing the teaspoon. By this the execution of testcases is delayed

NOTE: we have a stylesheets folder with .sass and .scss files in it. Removing the stylesheets folder is not giving the below deprecation warnings

$ RAILS_ENV=test bundle exec teaspoon --coverage=default

Found the solution, we excluded the stylesheet scanning by teaspoon via restricting the precompile config to js files only in test environment.

     Rails.application.config.assets.precompile = %w( *.js)

• Other evnvironments can have assets folder included meaning using the pattern of all js and css files in the above precompile config.

NOTE: (test environement is passed via RAILS_ENV while running teaspoon command in command prompt to have condition in assets.rb file).
