Question

尝试使用jUnit和REST Web服务。写了下面的类和测试类并进行了测试。要么我错误地写了测试，要么写错了服务。

我认为它应return "50"; 或
是应该返回路径还是50？那我怎么写那个测试呢？

班级：

@Path("/QAService")
public class QAService {
    @GET()
    //@Path("/")
    @Produces("text/plain")
    public String getServiceInfo() {
        return "50";
    }

班上的考试：

public class QAServiceTest {
    @Test
    public void testgetServiceInfo() {

        String expected = "50";   

        //create static variable to call non-static variable. assertEquals.
        QAService qas = new QAService();
        qas.getServiceInfo();
        assertEquals(expected, qas);
    }

但得到了测试结果：

expected:<50> but was:<com.hey.BLA.zurich.QAService@52bb855b>

Answer 1

你可能意味着：

assertEquals(expected, qas.getServiceInfo());

jUnit assertEquals字符串返回“50”预期“50”，但没有返回任何测试
