Problem with Cucumber setup

[Earthworn]

Hi, i followed the Quickstart guide and tried to run die example tests. I m on Windows 10 When i call cargo test -p cucumber --test example it fails instantly with: (error: package cucumber cannot be tested because it requires dev-dependencies and is not a member of the workspace) I also tried cargo test --test example then it does start to compile but fails with: could not compile quickstart_2 (test "example") due to previous error; 1 warning emitted Here is an extract of the warning:

my cargo.toml file is this:

[package]
name = "quickstart_2"
version = "0.1.0"
edition = "2021"

[dependencies]

[dev-dependencies]
cucumber = "0.20"
futures = "0.3"

[[test]]
name = "example"
harness = false

My example.rs in tests is this:

use cucumber::{given, World};

// These `Cat` definitions would normally be inside your project's code, 
// not test code, but we create them here for the show case.
#[derive(Debug, Default)]
struct Cat {
    pub hungry: bool,
}

impl Cat {
    fn feed(&mut self) {
        self.hungry = false;
    }
}

// `World` is your shared, likely mutable state.
// Cucumber constructs it via `Default::default()` for each scenario. 
#[derive(Debug, Default, World)]
pub struct AnimalWorld {
    cat: Cat,
}

// Steps are defined with `given`, `when` and `then` attributes.
#[given("a hungry cat")]
fn hungry_cat(world: &mut AnimalWorld) {
    world.cat.hungry = true;
}

// This runs before everything else, so you can setup things here.
fn main() {
    // You may choose any executor you like (`tokio`, `async-std`, etc.).
    // You may even have an `async` main, it doesn't matter. The point is that
    // Cucumber is composable. :)
    futures::executor::block_on(AnimalWorld::run("tests/features/book"));
}

and my file structure is: src main.rs tests features book animal.feature cargo.toml cargo.lock

Not sure whats going on and how to fix. Can someone help me?

[Earthworn]

I fixed it. For anyone having the same issue: Just reinstall rust.

Still would be glad if someone could explain what my problem was.

@Earthworn glad you've resolved this. Running cargo test --test example is the correct way.

When i call cargo test -p cucumber --test example it fails instantly with: (error: package cucumber cannot be tested because it requires dev-dependencies and is not a member of the workspace)

This is because it was meant to run from this repo root (after doing git clone https://github.com/cucumber-rs/cucumber).

I think I should strip that -p cucumber in the Book, because it definitely confuses newbies, not familiar with Rust tooling. Thanks for pointing that out.

I also tried cargo test --test example then it does start to compile but fails with: could not compile quickstart_2 (test "example") due to previous error; 1 warning emitted Here is an extract of the warning:

Regarding this... it's the issue with Rust toolchain on Windows, which I'm not familiar with. This, however, steps out of scope of this repo. I'm glad that "just reboot/reinstall" trick worked for you.

I think I should strip that -p cucumber in the Book, because it definitely confuses newbies, not familiar with Rust tooling. Thanks for pointing that out.

Actually, I couldn't find such command anywhere in the Book or in the docs. Could you point where exactly you got it from?

UPD: Oh... it's on the generated images, because they are recorded from running in this repo.

@Earthworn edge Book now contains renewed GIFs (you may need hard reload pages to see them).

Hi, thank you for the clarification. Yeah i m obivousliy a newbie and look for a way to run the test.
