Crate testlog

testlog

A tiny, focused crate that provides a single macro: test_log!

This macro prints to stderr only when tests are running and only for the crate where it’s used. Perfect for debugging test failures without cluttering production output.

Usage

use testlog::test_log;

#[test]
fn my_test() {
    test_log!("Debug info: {}", some_value);
    // Output only appears when running tests
}

Macros

test_log

A macro that prints to stderr only during test execution for the current crate.
