Olá pessoal, Blz?

O teste com a DAO ocorre com sucesso. Porém, não estou conseguindo executar o teste do Controller de Produto.

Alguem poderia de um help?

ProdutosControllerTest

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import com.coding.house.store.conf.AppWebConfiguration;
import com.coding.house.store.conf.DataSourceConfigurationTest;
import com.coding.house.store.conf.JPAConfiguration;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = {JPAConfiguration.class, AppWebConfiguration.class, DataSourceConfigurationTest.class})
@ActiveProfiles("test")
public class ProductsControllerTest {

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

    @Test
    public void mustReturnToHome() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/")).andExpect(MockMvcResultMatchers.forwardedUrl("/WEB-INF/views/home.jsp"));
    }
}

Erro do Console:

Olá Jhonatan, tudo bem?

Pelo que vi no seu stacktrace parece que está faltando importar o jackson no seu pom.xml. Imagino que na sua classe Controller tenha algum método com a anotação

@ResponseBody

retornando um json, só que ele não está achando uma forma de transformar seu objeto em json, que seria a responsabilidade do jackson. Tente verificar seu pom.xml e veja se a dependência do jackson está presente.

Nao entendi muito bem isso que voce disse sobre a annotation @ResponseBody

Eu fiz o desafio de algumas aulas atrás onde deveria retornar na pagina de detalhes em forma de XML e JSON.

Acredito que o problema esteja na sua versão importada do jackson. Ela é 2.5.1 e pelo que vi não tem a classe FormatFeature, tente alterar a versão de suas dependências do jackson para uma mais nova, por exemplo 2.7.7
