Using Logger.info and Logger.debug in ExUnit tests

By default in the test env, Phoenix doesn't show Logger.debug/Logger.info
outputs in the console.
Logger provides 4 printing levels:
- info (allows errors, warns, debugs, infos)
- debug (allows errors, warns, debugs)
- warn (allows errors, warns)
- error (allows errors)
By default the :warn
level is turned on. It means that only Logger.warn
and Logger.error
is printed to the output.
If you'd like to use another two, go to your config/test.exs file and you'll probably see:
# Print only warnings and errors during test
config :logger, level: :warn
Just change the line to the proper level (:debug
or :info
), and you're ready to go:
# Print all (errors, warnings, debugs and infos) during tests
config :logger, level: :info
