【问题描述】：
Hej 我在使用 1.5.5 和 1.5.6 时尝试过 TestNG 和 powerMockito 1.5.x 有一些问题。问题是当我尝试验证一个非空的构造函数时。
我已经检查了很多关于从 PowerMockTestCase 扩展等的示例，但它们似乎对我不起作用。
package com.cdev.common;
public class TestSubject {
String data;
String context;
public TestSubject()
{
this.data = "Mock!!";
this.context = "PowerMockito";
}
public TestSubject(String data)
{
this.data = data;
this.context = "PowerMockito";
}
public TestSubject(String data,String context)
{
this.data = data;
this.context = context;
}
public String getData()
{
throw new UnsupportedOperationException();
}
public String getContext()
{
throw new UnsupportedOperationException();
}
public boolean isNew()
{
throw new UnsupportedOperationException();
}
}
这是 testNG 测试：
package com.cdev.common.test;
import com.cdev.common.*;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.testng.Assert;
import org.testng.annotations.Test;
@PrepareForTest({TestSubject.class})
public class TestSubjectTest{
@Test
public void TestSubject() throws Exception
{
System.out.println("======== Test ==================");
TestSubject mockTestSubject = PowerMockito.mock(TestSubject.class);
PowerMockito.whenNew(TestSubject.class).withArguments("A", "B").thenReturn(mockTestSubject);
PowerMockito.when(mockTestSubject.getData()).thenReturn("A");
PowerMockito.when(mockTestSubject.getContext()).thenReturn("B");
PowerMockito.when(mockTestSubject.isNew()).thenReturn(true);
PowerMockito.verifyNew(TestSubject.class).withArguments("A", "B");
TestSubject lala = new TestSubject("A","B");
System.out.println(lala.getData());
System.out.println(lala.isNew());
Assert.assertTrue(lala.getData().equals("A"), "Not equal");
}
}
这给了我这个输出：
[TestNG] Running:
/tmp/testng-eclipse--2099806353/testng-customsuite.xml
======== Test ==================
FAILED: TestSubject
java.lang.AssertionError: Wanted but not invoked com.cdev.common.TestSubject(
"A",
"B"
);
Actually, there were zero interactions with this mock.

那么......你为什么要嘲笑这样的事情？新对象似乎并不深入依赖项或任何内容。您可以使用 setter/getter 或反射显式测试。

Hej 这只是概念验证或测试以控制 powermockito，所以这不是真正的生产代码，如果你知道我的意思的话。
