java - jUnit if/else 语句 java

Question

我是 JUnit 测试的新手，在为 if/else 语句编写测试时遇到问题。我编写了一个简单的 JUnit 测试，但它跳过所有 if else 语句(我需要检查传递的 url 进行检查)并转到最后一个 else 语句。我相信这里的问题是 url 本身没有被检查。我如何在 JUnit 中测试其余的 if/else 语句(首先测试 if/else)。我正在添加我的 java 类和 Junit 测试。

protected void doGet(HttpServletRequest req, HttpServletResponse resp)
        throws ServletException, IOException
{
    JSONObject jsonObject = null;
    int assetId = 0;
    int journeyId = 0;
    Date selectedDate = new Date();     
    selectedDate.setTime(selectedDate.getTime() - 30 * 1000 * 60 * 60 * 24);


        String[] comps = req.getRequestURI().split("/");
        if (comps.length == 6)
        {
            assetId = Integer.parseInt(comps[5]);

            jsonObject = getJourneys(assetId, selectedDate);
            resp.getWriter().write(jsonObject.toString(4));
        }
        else if (comps.length == 7)
        {
            assetId = Integer.parseInt(comps[5]);
            journeyId = Integer.parseInt(comps[6]);

            jsonObject = getAssetJourneys(assetId, journeyId);
            resp.getWriter().write(jsonObject.toString(4));
        }
        else
        {
            resp.getWriter().write("Entered url is in wrong format, please check it and try again");
        }
    }




@Test
public void testUrl() throws Exception
{
    GPSHistoryService gpsService = mock(GPSHistoryService.class);
    HttpServletRequest req = mock(HttpServletRequest.class);
    HttpServletResponse resp = mock(HttpServletResponse.class);
    PrintWriter pw = mock(PrintWriter.class);

    when(resp.getWriter()).thenReturn(pw);
    when(req.getRequestURI()).thenReturn("url");

    JourneyRestApiServlet jras = new JourneyRestApiServlet(gpsService);
    jras.doGet(req, resp);

    verify(pw).write("Entered url is in wrong format, please check it and try again");
}

您应该在另一个junit测试中修改您的模拟when

when(req.getRequestURI()).thenReturn("url/url/url/url/url/url/url/url");

并制作尽可能多的 junit 以便正确测试它
