How do you make a test that doesn't fail if dotenv() doesn't find the .env file?

[valentinegb]

In my Rust program, I have a .env file for my environmental variables when I run the tests on my computer. However, I also run the tests via a GitHub workflow, where I have a repository secret defined. Currently, these tests all fail in the workflow because there is no .env file present. How should I resolve this?

Right now I'm just doing this:

#![allow(unused_must_use)]
dotenv();

But I'd rather not have to disable any warnings.

dotenv() returns Result. You can handle the error or ignore it.

dotenv().ok(); // discards the error if there is one
