Represents a shared user-defined state for a Cucumber run. It lives on per-scenario basis.

This crate doesn’t provide out-of-box solution for managing state shared across scenarios, because we want some friction there to avoid tests being dependent on each other. If your workflow needs a way to share state between scenarios (ex. database connection pool), we recommend using once_cell crate or organize it other way via shared state.

Required Associated Types

type Error: Display

Error of creating a new World instance.

Required Methods

fn new() -> impl Future<Output = Result<Self, Self::Error>>

Creates a new World instance.

Provided Methods

fn collection() -> Collection<Self>

where Self: Debug + WorldInventory,

Available on crate feature macros only.

Returns runner for tests with auto-wired steps marked by given, when and then attributes.

fn cucumber<I: AsRef<Path>>( ) -> Cucumber<Self, Basic, I, Basic<Self>, Summarize<Normalize<Self, Basic>>>

where Self: Debug + WorldInventory,

Available on crate feature macros only.

Returns default Cucumber with all the auto-wired Steps.

fn run<I: AsRef<Path>>(input: I) -> impl Future<Output = ()>

where Self: Debug + WorldInventory,

Available on crate feature macros only.

Runs Cucumber.

Features sourced by Parser are fed into Runner where the later produces events handled by Writer.

Panics

If encountered errors while parsing Features or at least one Step panicked.

fn filter_run<I, F>(input: I, filter: F) -> impl Future<Output = ()>

where Self: Debug + WorldInventory, I: AsRef<Path>, F: Fn(&Feature, Option<&Rule>, &Scenario) -> bool + 'static,

Available on crate feature macros only.

Runs Cucumber with Scenarios filter.

Features sourced by Parser are fed into Runner where the later produces events handled by Writer.

Panics

If encountered errors while parsing Features or at least one Step panicked.

Object Safety

This trait is not object safe.
