            You are using the React on Rails test helper.
            Either you used:
              ReactOnRails::TestHelper.configure_rspec_to_compile_assets or
              ReactOnRails::TestHelper.ensure_assets_compiled
            but you did not specify the config.build_test_command

            React on Rails is aborting your test run

            If you wish to use the config/#{ReactOnRails::PackerUtils.packer_type}.yml compile option for tests
            them remove your call to the ReactOnRails test helper.
