Play Framework 2.2.2 - Java -Testing Controllers With Mock Objects

[Damien Gallagher]

Is anyone aware of any examples of testing a Java based Play Framework controller by setting mock objects? I am using Spring in my Play project so all my controller methods are not static.

Testing the tradional way, Play shows my controller as having static methods and I just cant see a way of how I can inject mocks into my object

Result result = callAction(
            controllers.routes.ref.LoginController.authenticate(),
        fakeRequest().withFormUrlEncodedBody(TestUtils.SUCCESSFUL_LOGIN_MAP)
    );

I have a number of services that need to be called in the LoginController and I would like to set those up as mocks

Any help is greatly appreciated

Thanks Damien

I am interested in what others do... what I did was Create an instance of my class manually and inject mock objects manually.  Then create a mock Context, set it as the current Context,  and just invoke your Controller instance directly:

( I use Mockito for mocks )

I am testing a Json REST service:

Invoke the controller

    Context.current.set(fakeContext(Json.toJson(

        new Object() {

          public String foo = "goodUser";

          public String password = "goodPassword";

        }).toString()));

    result = auth.authenticate();

    assertThat(status(result)).isEqualTo(Status.BAD_REQUEST);

Make the fake context

  public static Context fakeContext(String body)

  {

    Request request = mock(Request.class);

    RequestBody requestBody = mock(RequestBody.class);

    when( request.body() ).thenReturn(requestBody);

   

    if(StringUtils.isNotEmpty(body))

    {

      when( request.method() ).thenReturn("POST");

      when( requestBody.asText() ).thenReturn(body);

     

      try

      {

        when( requestBody.asJson() ).thenReturn(new ObjectMapper().readTree(body));

      }

      catch (IOException e)

      {

        throw new RuntimeException(e);

      }

     

    }

   

    when(request.host()).thenReturn("localhost");

   

    RequestHeader header = mock(RequestHeader.class);

    when( header.host()).thenReturn("localhost");

   

    Context ctx = mock(Context.class);

    when(ctx._requestHeader()).thenReturn(header);

    when(ctx.request()).thenReturn(request);

    when(ctx.flash()).thenReturn(new Flash(new HashMap<String,String>()));

    when(ctx.lang()).thenReturn(Lang.forCode("en"));

   

   

   

    return ctx;

  }

Thanks guys

I am able to use PowerMock to mock the tests but not with the standard items used the play framework

Ill keep playing with it
