How do you print in a Go test using the “testing” package?

Question

I\'m running a test in Go with a statement to print something (i.e. for debugging of tests) but it\'s not printing anything.

func TestPrintSomething(t *testi

t.Log and t.Logf do print out in your test but can often be missed as it prints on the same line as your test. What I do is Log them in a way that makes them stand out, ie

t.Run("FindIntercomUserAndReturnID should find an intercom user", func(t *testing.T) {

    id, err := ic.FindIntercomUserAndReturnID("test3@test.com")
    assert.Nil(t, err)
    assert.NotNil(t, id)

    t.Logf("\n\nid: %v\n\n", *id)
})

which prints it to the terminal as,

=== RUN   TestIntercom
=== RUN   TestIntercom/FindIntercomUserAndReturnID_should_find_an_intercom_user
    TestIntercom/FindIntercomUserAndReturnID_should_find_an_intercom_user: intercom_test.go:34:
