What?

RSpec (or Jasmine/Mocha) style tests for native Java 8, a bit like the following:

@RunWith(JarSpecJUnitRunner.class)
public class MinimalSpec implements Specification {
    @Override
    public SpecificationNode root() {
        return describe("This specification",
            it("contains a statement with a test", () -> assertTrue(true))
        );
    }
}

Why?

Allows for more expressive test names without very_long_underscore_ridden_test_method_names, and for more flexible test structure. Java 8 features such as lambda expressions make this possible with less boilerplate. See wiki/Motivation for more.

How?

1. Add JarSpec to your project dependencies. See below for Maven and the dependency info page for other build tools.

2. Start writing specs! See wiki/Implementing Specifications for more details, or the project's own tests for examples.

Using Maven

Add the dependency to your pom:

    <dependencies>
        ....
        <dependency>
            <groupId>io.hgc</groupId>
            <artifactId>jarspec</artifactId>
            <version>2.0.0</version>
            <scope>test</scope>
        </dependency>
        ....
    </dependencies>

Configure SureFire to pick up classes named *Spec (although you can stick with the default *Test convention if you prefer):

    <build>
        <plugins>
            ...
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.20</version>
                <configuration>
                    <includes>
                        <include>**/*Spec.java</include>
                    </includes>
                </configuration>
            </plugin>
            ...
        </plugins>
    </build>

When?

The current release on Maven Central is stable. See open milestones for further planned features. Releases numbers follow the Semantic Versioning specification for backwards compatibility.
