Get Coverage stats when tests are in another package

Question

My tests aren\'t in the same package as my code. I find this a less cluttered way of organising a codebase with a lot of test files, and I\'ve read that it\'s a good idea in

Answer 1

As it is mentioned in comments you can run

go test -cover -coverpkg "api_client" "api_client_tests"

to run the tests with coverage.

But splitting code files from tests files to a different directories isn't a Go's way.

I suppose that you want to have a black-box testing(nothing package-private stuff can be accessible outside, even for tests).

To accomplish this it's allowed to have tests in another package(without moving the files). Example:

api_client.go

package api_client

// will not be accessible outside of the package
var privateVar = 10

func Method() {
}

api_client_test.go

package api_client_tests

import "testing"

func TestClient(t *testing.T) {
    Method()
}
