How to run JUnit SpringJUnit4ClassRunner with Parametrized?

You can use SpringClassRule and SpringMethodRule - supplied with Spring

import org.junit.ClassRule;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.springframework.test.context.junit4.rules.SpringClassRule;
import org.springframework.test.context.junit4.rules.SpringMethodRule;

@RunWith(Parameterized.class)
@ContextConfiguration(...)
public class MyTest {

    @ClassRule
    public static final SpringClassRule SPRING_CLASS_RULE = new SpringClassRule();

    @Rule
    public final SpringMethodRule springMethodRule = new SpringMethodRule();

    ...

There are at least 2 options to do that:

Following http://www.blog.project13.pl/index.php/coding/1077/runwith-junit4-with-both-springjunit4classrunner-and-parameterized/

Your test needs to look something like this:

 @RunWith(Parameterized.class)
 @ContextConfiguration(classes = {ApplicationConfigTest.class})
 public class ServiceTest {

     private TestContextManager testContextManager;

     @Before
     public void setUpContext() throws Exception {
         //this is where the magic happens, we actually do "by hand" what the spring runner would do for us,
        // read the JavaDoc for the class bellow to know exactly what it does, the method names are quite accurate though
       this.testContextManager = new TestContextManager(getClass());
       this.testContextManager.prepareTestInstance(this);
     }
     ...
 }

There is a github project https://github.com/mmichaelis/spring-aware-rule, which builds on previous blog, but adds support in a generalized way

@SuppressWarnings("InstanceMethodNamingConvention")
@ContextConfiguration(classes = {ServiceTest.class})
public class SpringAwareTest {

    @ClassRule
    public static final SpringAware SPRING_AWARE = SpringAware.forClass(SpringAwareTest.class);

    @Rule
    public TestRule springAwareMethod = SPRING_AWARE.forInstance(this);

    @Rule
    public TestName testName = new TestName();

    ...
}

So you can have a basic class implementing one of the approaches, and all tests inheriting from it.

There is another solution with JUnit 4.12 without the need of Spring 4.2+.

JUnit 4.12 introduces ParametersRunnerFactory which allow to combine parameterized test and Spring injection.

public class SpringParametersRunnerFactory implements ParametersRunnerFactory {
@Override
  public Runner createRunnerForTestWithParameters(TestWithParameters test) throws InitializationError {
    final BlockJUnit4ClassRunnerWithParameters runnerWithParameters = new BlockJUnit4ClassRunnerWithParameters(test);
    return new SpringJUnit4ClassRunner(test.getTestClass().getJavaClass()) {
      @Override
      protected Object createTest() throws Exception {
        final Object testInstance = runnerWithParameters.createTest();
        getTestContextManager().prepareTestInstance(testInstance);
        return testInstance;
      }
    };
  }
}

The factory can be added to test class to give full Spring support like test transaction, reinit dirty context and servlet test.

@UseParametersRunnerFactory(SpringParametersRunnerFactory.class)
@RunWith(Parameterized.class)
@ContextConfiguration(locations = {"/test-context.xml", "/mvc-context.xml"})
@WebAppConfiguration
@Transactional
@TransactionConfiguration
public class MyTransactionalTest {

  @Autowired
  private WebApplicationContext context;

  ...
}

If you need Spring context inside @Parameters static method to provide parameters to test instances, please see my answer here How can I use the Parameterized JUnit test runner with a field that's injected using Spring?.
