Set environment variable for Go tests
Solution 1
FOO=BAR bash -c 'go list ./... | grep -v vendor | xargs -n1 go test -timeout=3s'
A good explanation why the original command doesn't work can be found in the answer to the question: https://unix.stackexchange.com/questions/134735/environment-variables-are-not-set-when-my-function-is-called-in-a-pipeline
Solution 2
I like to use godotenv in command mode
godotenv -f ./.env go test ./internal/... -cover
Solution 3
That's not how setting variables for pipes works. See:
FOO=BAR echo "AAA" | FOO=WAZ printenv | grep FOO

I am trying to run my Go tests like this, setting an environment variable:
FOO=BAR go list ./... | grep -v vendor | xargs -n1 go test -timeout=3s
Inside my tests I do:
log.Print(os.Getenv("FOO"))
Which returns an empty string. Why is FOO not set?
