cert, err := tls.LoadX509KeyPair(os.Getenv("CERT"), os.Getenv("KEY"))
if err != nil
return err
I want to write a unit test for a function that contains this snippet of code. However, my test environment will never have any content in os.Getenv("CERT")/os.Getenv("KEY"). This makes the code(tls.LoadX509KeyPair()) return an error, which doesn't let me test the function.
How should I go about mocking/modifying this snippet?

Refactor. If the code under test relies on an environment that isn't reproduced under test, either you can't test it or you have to refactor it.

No, there's nothing wrong with it. I mean the broader sense of "environment" - the environment variables, local files (e.g. certificates), etc.

This works by defining vars for the certFile and keyFile and then overriding them in the test environment.
//..
var certFile = os.Getenv("CERT")
var keyFile = os.Getenv("KEY")
//...
cert, err := tls.LoadX509KeyPair(certFile, keyFile)
if err != nil
return err
Follow the below link to see how to override the vars in a test env.
