An implementation of the Cucumber testing framework for Rust. Fully native, no external test runners or dependencies.
Create a directory called tests/
in your project root and create a test target of your choice. In this example we will name it cucumber.rs
.
Add this to your Cargo.toml
:
```toml [[test]] name = "cucumber" harness = false # Allows Cucumber to print output instead of libtest
[dev-dependencies] cucumber = "^0.1" ```
Create a directory called features/
and put a feature file in it named something like example.feature
. It might look like:
```gherkin Feature: Example feature
Scenario: An example scenario Given I am trying out Cucumber When I consider what I am doing Then I am interested in ATDD And we can implement rules with regex
```
And here's an example of implementing those steps using our tests/cucumber.rs
file:
```rust
extern crate cucumber;
pub struct World { // You can use this struct for mutable context in scenarios. }
impl std::default::Default for World { fn default() -> World { // This function is called every time a new scenario is started World { } } }
cucumber! { features: "./features"; // Path to our feature files world: World; // Any type that implements Default can be the world
given "I am trying out Cucumber" |world| {
// Set up your context in given steps
};
when "I consider what I am doing" |world| {
// Take actions
};
then "I am interested in ATDD" |world| {
// Check that the outcomes to be observed have occurred
};
then regex r"^we can (.*) rules with regex$" |world, matches| {
// And access them as an array
assert!(matches[1] == "implement");
};
} ```
The full gamut of Cucumber's Gherkin language is implemented by the gherkin-rust project. Features such as data tables and docstrings will be progressively implemented prior to v1.0.0.
