junit-parameters

junit-parameters enables adding parameters to JUnit 4 test methods.

Code examples

• Annotate your test class with the JUnitParameters test runner:

@RunWith(JUnitParameters.class)
public class ParametersGeneratorTest {
}

• Implement the interface ParameterGenerator:

public class OneParameterGenerator implements ParameterGenerator {

    @Override
    public Iterable<Object[]> parameters() {
        return Arrays.asList(new Object[][] { { "foo" }, { "bar" }, 
                                              { "baz" }, { "code" },
                                              { "java" } });
    }
}

• Use it in your test with the @ParameterProvider annotation

@Test
@ParameterProvider(OneParameterGenerator.class)
public void injectSingleParam(String parameter) {
}

The JUnit test method will be invoked with each parameter created by the ParameterGenerator factory used in the test.

Tests

There are some tests available at src/test/java. It's possible to run the JUnitParametersTest test class and see the results.
