Hey @liangyongrui 👋

Sorry for taking so long to circle around to this! There are two things going on in that sample:

The log events are captured by cargo test, which only shows them for tests that fail, unless you pass the --nocapture flag.
The default environment variable will only show error and above events, so when running cargo test you either need an environment variable like RUST_LOG=info, or add a .filter_level(log::LevelFilter::Info) to your builder.
