This crate provides an easy way to enable logging in tests that use
[tracing](https://tracing.rs/), even if they're async. Additionally, it adds a
way to assert that certain things were logged.
The focus is on testing the logging, not on debugging the tests. That's why the
library ensures that the logs do not depend on external state. For example, the
`RUST_LOG` env variable is not used for log filtering.
Similar crates:

running tests

More powerful assertions that also allow analyzing spans
