+test-log
+========
+
+- [Documentation][docs-rs]
+- [Changelog](CHANGELOG.md)
+
+**test-log** is a crate that takes care of automatically initializing
+logging and/or tracing for Rust tests.
+
+When running Rust tests it can often be helpful to have easy access to
+the verbose log messages emitted by the code under test. Commonly, these
+log messages may be coming from the [`log`][log] crate or being emitted
+through the [`tracing`][tracing] infrastructure.
+
+The problem with either -- in the context of testing -- is that some
+form of initialization is required in order to make these crate's
+messages appear on a standard output stream.
+
+The commonly used [`env_logger`](https://crates.io/crates/env_logger)
+(which provides an easy way to configure `log` based logging), for
+example, needs to be initialized like this:
+```rust
+let _ = env_logger::builder().is_test(true).try_init();
+```
+in **each and every** test.
+
+Similarly, `tracing` based solutions require a subscriber to be
+registered that writes events/spans to the console.
+
+This crate takes care of this per-test initialization in an intuitive
+way.
+
+
+Usage
+-----
+
+The crate provides a custom `#[test]` attribute that, when used for
+running a particular test, takes care of initializing `log` and/or
+`tracing` beforehand.
+
+#### Example
+
+As such, usage is as simple as importing and using said attribute:
+```rust
+use test_log::test;
+
+#[test]
+fn it_works() {
+ info!("Checking whether it still works...");
+ assert_eq!(2 + 2, 4);
+ info!("Looks good!");
+}
+```
+
+It is of course also possible to initialize logging for a chosen set of
+tests, by only annotating these with the custom attribute:
+```rust
+#[test_log::test]
+fn it_still_works() {
+ // ...
+}
+```
+
+You can also wrap another attribute. For example, suppose you use
+[`#[tokio::test]`][tokio-test] to run async tests:
+```rust
+use test_log::test;
+
+#[test(tokio::test)]
+async fn it_still_works() {
+ // ...
+}
+```
+
+#### Logging Configuration
+
+As usual when running `cargo test`, the output is captured by the
+framework by default and only shown on test failure. The `--nocapture`
+argument can be supplied in order to overwrite this setting. E.g.,
+```bash
+$ cargo test -- --nocapture
+```
+
+Furthermore, the `RUST_LOG` environment variable is honored and can be
+used to influence the log level to work with (among other things).
+Please refer to the [`env_logger` docs][env-docs-rs] for more
+information.
+
+If the `trace` feature is enabled, the `RUST_LOG_SPAN_EVENTS`
+environment variable can be used to configure the tracing subscriber to
+log synthesized events at points in the span lifecycle. Set the variable
+to a comma-separated list of events you want to see. For example,
+`RUST_LOG_SPAN_EVENTS=full` or `RUST_LOG_SPAN_EVENTS=new,close`.
+
+Valid events are `new`, `enter`, `exit`, `close`, `active`, and `full`.
+See the [`tracing_subscriber` docs][tracing-events-docs-rs] for details
+on what the events mean.
+
+#### Features
+
+The crate comes with two features:
+- `log`, enabled by default, controls initialization for the `log`
+ crate.
+- `trace`, disabled by default, controls initialization for the
+ `tracing` crate.
+
+Depending on what backend the crate-under-test (and its dependencies)
+use, the respective feature should be enabled to make messages that are
+emitted by the test manifest on the console.
+
+Note that as a user you are required to explicitly add `env_logger` or
+`tracing-subscriber` as a dependency to your project-under-test (when
+enabling the `log` or `trace` feature, respectively). E.g.,
+
+```toml
+[dev-dependencies]
+env_logger = "*"
+tracing = {version = "0.1", default-features = false}
+tracing-subscriber = {version = "0.3", default-features = false, features = ["env-filter", "fmt"]}
+```

+/// The attribute can be used to define a test that has the `env_logger`

+///
+/// # Example
+///
+/// Specify the attribute on a per-test basis:
+/// ```rust
+/// # // doctests seemingly run in a slightly different environment where
+/// # // `super`, which is what our macro makes use of, is not available.
+/// # // By having a fake module here we work around that problem.
+/// # #[cfg(feature = "log")]
+/// # mod fordoctest {
+/// # use logging::info;
+/// # // Note that no test would actually run, regardless of `no_run`,
+/// # // because we do not invoke the function.

+/// fn it_works() {
+/// info!("Checking whether it still works...");
+/// assert_eq!(2 + 2, 4);
+/// info!("Looks good!");
