junit测试和Web服务

Question

我有一个测试单元测试用于Web服务的crud，但我遇到了问题。当我运行所有测试都工作，但当我同时运行所有这些测试的出版物（例如）我无法更新或恢复，因为它给出500错误，但如果我一次只运行一个作品。我该怎么办才能一次完成所有事情？

//@Ignore
    @Test
    public void inserirPublicacao() throws MalformedURLException, IOException{
        int code = 0;

        PublicacaoDao dao = new PublicacaoDao();
        Publicacao pb = new Publicacao();

        String localidade = "br 212";
        String descricao = "selvagens na estrada";
        long idUsuario = 2;

        JSONObject jsonObject = new JSONObject();

        //Armazena dados em um Objeto JSON
        jsonObject.put("localidade", localidade);
        jsonObject.put("descricao", descricao);
        jsonObject.put("codigo", idUsuario);    

        Gson gson = new Gson();
        String Json = gson.toJson(jsonObject);

        URL url;

            connection.disconnect();

            pb = dao.recuperar((long)5);

        assertEquals(204,code);

            connection.setDoOutput(true);
            connection.setRequestMethod("DELETE");

            code = connection.getResponseCode();

        assertEquals(204,code);
    }

如果我一起运行，那就是我做的事情

我单独运行的问题可以解决所有问题
