Cucumber Trellis

Create a test "trellis" for Cucumber.

You can create a test suite for Cucumber, with each test implemented in a file, linked to a Gherkin feature file.

Each test implements a trait CucumberTest and this test is registered in the "trellis".

Finally, all tests are executed in parallel, and the trellis waits for all tests to finish.

Installation

cargo add cucumber cucumber-trellis

Usage

First, allows Cucumber to print output instead of libtest by adding these lines in your Cargo.toml:

[[test]]

name = "cucumber"

harness = false

Then, put feature files in tests/features directory, and put the following code in tests/cucumber.rs:

mod tests;

fn main() {
    let mut trellis = cucumber_trellis::CucumberTrellis::new(None);

    trellis.add_test::<tests::example::SimpleTest>();

    trellis.run_tests();
}

After that , in tests/tests/example.rs, implements the trait cucumber_trellis::CucumberTest, like this:

use cucumber_trellis::CucumberTest;
use cucumber::World;

#[derive(World, Debug)]
pub(in super::super) struct SimpleTest;

impl CucumberTest for SimpleTest {
    const NAME: &'static str = "simple-test";
}

// Implement here, the steps according the file `tests/features/simple-test.feature`
// ...

Don't forget the file tests/tests/mod.rs:

pub(super) mod example;

Finally, run the tests:

cargo test --test cucumber

Example

You have an example in the tests directory.
