# Description
Test runner now uses annotations instead of magic function names to pick
up code to run. Additionally skipping tests is now done on annotation
level so skipping and unskipping a test no longer requires changes to
the test code

In order for a function to be picked up by the test runner it needs to
meet following criteria:
* Needs to be private (all exported functions are ignored)
* Needs to contain one of valid annotations (and only the annotation)
directly above the definition, all other comments are ignored

Following are considered valid annotations:
* \# test
* \# test-skip
* \# before-all
* \# before-each
* \# after-each
* \# after-all

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the
standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
