Question

Hej我在TestNG和powerMockito 1.5.x上遇到了一些问题我试过1.5.5和1.5.6。问题是当我尝试验证非空的构造函数时。

我已经检查过一些关于从PowerMockTestCase等扩展的例子，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

java.lang.AssertionError: Wanted but not invoked com.cdev.common.TestSubject(

Answer 1

您需要在调用完成后将verifyNew调用移动到：

TestSubject lala = new TestSubject("A","B");
PowerMockito.verifyNew(TestSubject.class).withArguments("A", "B");

Answer 2

按照说明操作：

@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);

    **TestSubject lala = new TestSubject("A","B");
    PowerMockito.verifyNew(TestSubject.class).withArguments("A", "B");**        

    System.out.println(lala.getData());
    System.out.println(lala.isNew());

    Assert.assertTrue(lala.getData().equals("A"), "Not equal");
}

输出：
