不能将类org.powermock.api.mockito.internal.mockmaker.PowerMockMa

Question

当使用TestNg + PowerMock + mockit时，我得到java.lang.ExceptionInInitializerError:

Caused by: java.lang.NullPointerException
at org.mockito.internal.configuration.plugins.Plugins.getStackTraceCleanerProvider(Plugins.java:17)

问题的根源是:

java.lang.ClassCastException: Cannot cast class org.powermock.api.mockito.internal.mockmaker.PowerMockMaker to interface org.mockito.plugins.MockMaker

我的依赖树:

[INFO] +- org.powermock:powermock-api-mockito:jar:1.6.2:test
[INFO] |  +- org.mockito:mockito-all:jar:1.10.19:test
[INFO] |  - org.powermock:powermock-api-support:jar:1.6.2:test

[INFO] |  - org.powermock:powermock-module-testng-common:jar:1.6.2:test

测试类:

@PrepareForTest({CrossSiteServletRequestFilter.class})
@PowerMockIgnore({"org.apache.log4j.*"})
@Test
public class CrossSiteServletRequestFilterTest extends PowerMockTestCase{
    @Mock
    private HttpServletRequest request;
    @BeforeSuite
    public void beforeSuite() {
        URL log4jCfg = CrossSiteServletRequestFilterTest.class.getClassLoader().getResource("log/log4j.xml");
        DOMConfigurator.configure(log4jCfg);
        MockitoAnnotations.initMocks(this); //<---It crashes here

我完全失去了这个错误，感谢任何帮助。

Answer 1

您不应该将MockitoAnnotations.initMocks与TestNG一起使用

Javadoc说它用于JUnit(我认为MockitoJUnitRunner/MockitoRule是一个更好的方法)，但不是用于TestNG。

BTW, PowerMockTestCase在使用TestNG时相当于MockitoJUnitRunner。所以，只要删除行，它应该可以工作。
