Struct cucumber::cli::Opts

pub struct Opts<Parser, Runner, Writer, Custom = Empty>
where
    Parser: Args,
    Runner: Args,
    Writer: Args,
    Custom: Args,
{
    pub re_filter: Option<Regex>,
    pub tags_filter: Option<TagOperation>,
    pub parser: Parser,
    pub runner: Runner,
    pub writer: Writer,
    pub custom: Custom,
}

Root CLI (command line interface) of a top-level Cucumber executor.

It combines all the nested CLIs of Parser, Runner and Writer, and may be extended with custom CLI options additionally.

Example

#[derive(clap::Args)] // also re-exported as `cli::Args`
struct CustomOpts {
    /// Additional time to wait in before hook.
    #[arg(
        long,
        value_parser = humantime::parse_duration,
    )]
    pre_pause: Option<Duration>,
}

let opts = cli::Opts::<_, _, _, CustomOpts>::parsed();
let pre_pause = opts.custom.pre_pause.unwrap_or_default();

MyWorld::cucumber()
    .before(move |_, _, _, _| time::sleep(pre_pause).boxed_local())
    .with_cli(opts)
    .run_and_exit("tests/features/readme")
    .await;

Fields

re_filter: Option<Regex>

Regex to filter scenarios by their name.

tags_filter: Option<TagOperation>

Tag expression to filter scenarios by.

Note: Tags from Feature, Rule and Scenario are merged together on filtering, so be careful about conflicting tags on different levels.

parser: Parser

Parser CLI options.

runner: Runner

Runner CLI options.

writer: Writer

Writer CLI options.

custom: Custom

Additional custom CLI options.

Implementations

impl<Parser, Runner, Writer, Custom> Opts<Parser, Runner, Writer, Custom>
