Mocking HttpServletResponse and passing it to ServletActionContext - And get the response object

Question

I have the following code.

    HttpServletResponse response = mock(HttpServletResponse.class);
    System.out.println("Response: " + response); // Prints "Mock for HttpServletResponse, hashCode: 2051435028"

    ServletActionContext.setResponse(response);
    System.out.println("Get Response: " + ServletActionContext.getResponse()); // Prints null.

ServletActionContext.getResponse()) prints null while response is not null when setting.

How do I get the response object?

Mockito, Struts2, JUnit

Answer 1

Okay. I got a workaround. For others help...

I checked the code of getResponse()

public static HttpServletResponse getResponse() {
    return (HttpServletResponse) ActionContext.getContext().get(HTTP_RESPONSE);
}

So I am already passing a mocked context object to the ServletActionContext . So before passing it, I am mocking the context call like this.

actionContext = mock(ActionContext.class);
when(actionContext.get(org.apache.struts2.StrutsStatics.HTTP_RESPONSE)).thenReturn(response);

Now it works!
