Could or should `#[gtest]` integrate with the test-log crate?

[mgeisler]

The test-log crate (https://crates.io/crates/test-log) allows you to configure logging, capture all logs, and display them on test failure. Without this, by default, you get no log output from unit tests.

Could or should googletest provide the same functionality?

Can you implement this yourself as a fixture?

Oh, nice, I didn't know we have support for fixtures!

I looked a bit more at test-log and see now that I can wrap the gtest attribute. So this works:

    #[test_log::test(gtest)]
    fn it_works() {
        let result: u64 = add(2, 2);
        log::info!("Got result: {result}!");
        expect_that!(result, eq(4));
    }

I'm sure a fixture could be used as well: test-log uses env_logger internally, so a fixture could run do the

        let _ = env_logger::builder().is_test(true).try_init();

line from their README. I didn't bother implementing this since the wrapping seems good enough.

i think it might make sense to have this as a first-class citizen in googletest: most crates use log and it makes sense to be able to see the output of logs (depending on the RUST_LOG setting, of course). you don't even need to pull in test-log, you can just pull in env_logger and do the one-liner mentioned by @mgeisler

thus i vote to re-open this issue (which i can't)
