您發(fā)布的代碼適用于我與最新版本的Mockito和Powermockito。也許你還沒有準(zhǔn)備A？

嘗試這個：

A.java

public class A {

private final String test;

public A(String test) {

this.test = test;

}

public String check() {

return "checked " + this.test;

}

}

MockA.java

import static org.hamcrest.MatcherAssert.assertThat;

import static org.hamcrest.Matchers.equalTo;

import static org.mockito.Mockito.mock;

import static org.mockito.Mockito.when;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.mockito.Mockito;

import org.powermock.api.mockito.PowerMockito;

import org.powermock.core.classloader.annotations.PrepareForTest;

import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)

@PrepareForTest(A.class)

public class MockA {

@Test

public void test_not_mocked() throws Throwable {

assertThat(new A("random string").check(), equalTo("checked random string"));

}

@Test

public void test_mocked() throws Throwable {

A a = mock(A.class);

when(a.check()).thenReturn("test");

PowerMockito.whenNew(A.class).withArguments(Mockito.anyString()).thenReturn(a);

assertThat(new A("random string").check(), equalTo("test"));

}

}

這兩個測試都應(yīng)該通過mockito 1.9.0，powermockito 1.4.12和junit 4.8.2
