如何在测试用例的方法中打印值？答案

【问题标题】：How to print the value within the method in testcase?如何在测试用例的方法中打印值？

【问题描述】：

我需要使用测试用例打印方法中的值。我的代码是：

public void testgetAllRatingElementsWeekNo() throws Exception
{
    String METHOD_NAME = "testgetAllRatingElementsWeekNo";
    log.entering(CLASS_NAME, METHOD_NAME);

    populateForTestMethodValues("1");
    populateWeekOfList();
    int allRatingElementsWeekNo = weeklyDlvyInstancesDashboardReportForm.getAllRatingElementsWeekNo();
    System.out.println("allRatingElementsWeekNo :" + allRatingElementsWeekNo );
    assertEquals("testgetAllRatingElementsWeekNo is Not Greater than Zero: ", allRatingElementsWeekNo > 0, allRatingElementsWeekNo);

    log.exiting(CLASS_NAME, METHOD_NAME);
}

我需要在抛出异常之前打印我的值。

【问题讨论】：

assertEquals(String, boolean, int) 看起来很奇怪
也许你想要assertFalse("not greater than zero: "+allRatingElementsWeekNo, allRatingElementsWeekNo > 0 )
好的，我试着让你知道结果..
@thilo，仍然抛出断言失败异常

【解决方案1】：

你可以添加一个 try 和 finally 块，最后你可以打印消息。我不知道这是否可以做得比这更好：

public void testgetAllRatingElementsWeekNo() throws Exception
{
try {
    String METHOD_NAME = "testgetAllRatingElementsWeekNo";
    log.entering(CLASS_NAME, METHOD_NAME);

    populateForTestMethodValues("1");
    populateWeekOfList();
    int allRatingElementsWeekNo = weeklyDlvyInstancesDashboardReportForm.getAllRatingElementsWeekNo();
    System.out.println("allRatingElementsWeekNo :" + allRatingElementsWeekNo );
    assertEquals("testgetAllRatingElementsWeekNo is Not Greater than Zero: ", allRatingElementsWeekNo > 0, allRatingElementsWeekNo);
} finally {
    log.exiting(CLASS_NAME, METHOD_NAME);
}
}
