✅解決法
- 「.circleci\config.yml」に、CircleCiでも「selenium-webdriver」を使用するように修正する

# Do not set this db to the same as development or production.
test:
<<: *default

host: <%= ENV.fetch("APP_DATABASE_HOST") { 'DB' } %>
# As with config/credentials.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password or a full connection URL as an environment
# variable when you boot the app. For example:
#
# DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# If the connection URL is provided in the special DATABASE_URL environment
# variable, Rails will automatically merge its configuration values on top of
# the values provided in this file. Alternatively, you can specify a connection
# URL environment variable explicitly:
#
# production:
# url: <%= ENV['MY_APP_DATABASE_URL'] %>
#
# Read https://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full overview on how database connection configuration can be specified.

database: <%= ENV['APP_DATABASE'] %>
username: <%= ENV['APP_DATABASE_USERNAME'] %>
