Have a Cuke, Duke

Cucumber runs on Java! This gem lets you write Cucumber steps in pure Java. Example:

package simple;
import java.util.Map;
import java.util.HashMap;
import cucumber.*;
import static org.junit.Assert.assertEquals;
public class StuffSteps {
    private final Map<String,String> cukes = new HashMap<String,String>();
    @Given("I have (\\d+) (.*) cukes")
    public void iHaveNCukes(String n, String color) {
        this.cukes.put(color, n);
    }
    @When("I add a table")
    public void iAddATable(Table table) {
        Map<String,String> hash = table.hashes().get(0);
        assertEquals("1", hash.get("a"));
        assertEquals("2", hash.get("b"));
    }
    @Then("I should have (\\d+) (.*) cukes")
    public void iShouldHaveNCukes(String n, String color) {
        if(!n.equals(cukes.get(color))) {
            throw new RuntimeException("Expected " + n + ", got " + cukes.get(color));
        }
    }
    public void thisIsNotAStep() {}
}

Building the cucumber-java gem

This is for hackers. If you just want to use Cucumber with Java, head straight to
the examples.

Install Maven

You can grab it here

Install JRuby

You can grab it here
Make sure you get 1.2.0 or later.

Install Hoe

This gem is needed to build the Cucumber Java gem

jruby -S gem install hoe --no-rdoc --no-ri

Build and install the gem

jruby -S rake gem
jruby -S gem install pkg/cucumber-java --no-rdoc --no-ri

Now head to the simple example and run it. It serves well as a testbed.
