How to write the positive and Negative test cases of same scenario in java?
提问by Adalarasan_Serangulam
I want to write the both test cases whether positive scenario and negative scenario.
我想编写两个测试用例，无论是正面场景还是负面场景。
My sample code is,
我的示例代码是，
/**
*
*/
public void testgetAsnAccuracyInstanceType() throws Exception
{
String METHOD_NAME = "testgetAsnAccuracyInstanceType";
log.entering(CLASS_NAME, METHOD_NAME);
//Rating Element "1" ASN Accuracy
populateForTestMethodValues("1");
populateWeekOfList();
List<WeeklyDeliveryInstanceTypeQO> asnAccuracyInstanceTypeList = weeklyDlvyInstancesDashboardReportForm.getAsnAccuracyInstanceType();
assertTrue("testgetASNAccuracyRatingElement is Not Empty: ", asnAccuracyInstanceTypeList.size() > 0);
log.exiting(CLASS_NAME, METHOD_NAME);
}

This line
这条线
assertTrue("testgetASNAccuracyRatingElement is Not Empty: ",
asnAccuracyInstanceTypeList.size() > 0);
is strictly equivalent to:
严格等同于：
assertFalse("testgetASNAccuracyRatingElement is Not Empty: ",
asnAccuracyInstanceTypeList.isEmpty());
(if that was what you were asking)
（如果那是你要问的）

How about this?
这个怎么样？
To assert it works:
断言它有效：
// use input data you expect results for
assertFalse("testgetASNAccuracyRatingElement is empty",
asnAccuracyInstanceTypeList.isEmpty());
To assert the negative case:
断言否定的情况：
// use input data you don't expect results for
assertTrue("testgetASNAccuracyRatingElement is not empty",
asnAccuracyInstanceTypeList.isEmpty());

Input/Test data decides if the test case is for positive or negative case.
输入/测试数据决定测试用例是用于正用例还是负用例。
So just have two test methods (one for positive and another for negative) and call with positive and negative data respectively.
所以只需有两种测试方法（一种用于阳性，另一种用于阴性）并分别调用阳性和阴性数据。
