Basics
This check is disabled by default.
Learn how to enable it via .credo.exs.
This check has a base priority of high and works with any version of Elixir.
Explanation
Direct environment reads bypass the env test override, and
System.put_env/2 mutates the whole VM – concurrent async: true
tests clobber each other and values leak into later tests. Route
through your env wrapper instead.
Check-Specific Parameters
Use the following parameters to configure this check:
:replacement
Your env wrapper module name, shown in the message.
This parameter defaults to "Ambient.Env".
:exempt_suffixes
File path suffixes exempt from the check (your wrapper's own file, and usually config/runtime.exs).
This parameter defaults to ["lib/ambient/env.ex"].
General Parameters
Like with all checks, general params can be applied.
Parameters can be configured via the .credo.exs config file.
