Play2 Java-使用表单测试控制器时InvalidPropertyException

我想测试一个名为

authenticate（）

的控制器方法，该方法具有非常简单的逻辑：从请求验证

电子邮件

和

密码

，并将结果作为JSON返回

public class Users extends Controller {

    static Form<User> userForm = Form.form(User.class);

    public static Result login() {
        return ok(views.html.users.login.render(userForm));
    }

    public static Result authenticate() {
        Form<User> filledForm = userForm.bindFromRequest();
        if (filledForm.hasErrors()) {
            return badRequest(views.html.users.login.render(filledForm));
        } else {
            ObjectNode result = Json.newObject();
            User u = filledForm.get();
            if (User.isAuthValid(u.email, u.password))
                result.put("status", "OK");
            else
                result.put("status", "Authentication failed");
            return ok(result);
        }
    }
}

但我在以下stacktrace中出错：

感谢您的建议/更正。

您需要在“假”应用程序中运行测试，以便绑定可以工作。所以，您的测试将如下所示：

@Test
public void callAuthenticate() {
    running(fakeApplication(), new Runnable() {
        public void run() {
            Map<String, String> formData = Maps.newHashMap();
            formData.put("email", "aaa@bbb.com");
            formData.put("password", "password");

            Result result = callAction(controllers.routes.ref.Users.authenticate(),
            fakeRequest().withFormUrlEncodedBody(formData));
            assertThat(status(result)).isEqualTo(Http.Status.OK);
        }
    }
}

@测试
public void callAuthenticate（）{
正在运行（fakeApplication（），new Runnable（））{
公开募捐{
Map formData=Maps.newHashMap（）；
formData.put（“电子邮件”aaa@bbb.com");
formData.put（“密码”、“密码”）；
结果=调用操作（controllers.routes.ref.Users.authenticate（），
FakereRequest（）。带有FormUrlEncodedBody（formData））；
assertThat（status（result））.isEqualTo（Http.status.OK）；
}
}
}
