/// ```ignore

/// ```
///
/// where all of `foo`, `bar`, and `baz`, would be recognized options to this
/// macro. The currently known options to this macro are:
///
/// * `run_in_browser` - requires that this test is run in a browser rather than
///   node.js, which is the default for executing tests.
/// * `run_in_dedicated_worker` - requires that this test is run in a web worker rather than
///   node.js, which is the default for executing tests.
/// * `run_in_shared_worker` - requires that this test is run in a shared worker rather than
///   node.js, which is the default for executing tests.
/// * `run_in_service_worker` - requires that this test is run in a service worker rather than
///   node.js, which is the default for executing tests.
///
/// This macro may be invoked at most one time per test suite (an entire binary
/// like `tests/foo.rs`, not per module)
