Question

我试图进行junit测试。

我正在使用：junit 4.10，
            easymock 3.0，
            powermock-core 1.4.10（使用javassist 3.15.0-GA），
            powermock-module-junit4 1.4.10，
            powermock-api-easymock 1.4.10
具有所有适当的依赖性。
我也试过powermock-core 1.5.5（javassist 3.18.0-GA）

（请注意，只有一个依赖项ognl（使用javassist 3.7.ga）

测试类：

@RunWith(PowerMockRunner.class)
@PrepareForTest({MyClassToBeTested.class})
public class MyClassToBeTestedTest{
    private MyClassToBeTested myClassToBeTested;
    @Before
    public void setUp() {
        // Partial mock with powermock
        myClassToBeTested = PowerMock.createPartialMock(MyClassToBeTested.class, "testMethod");
    }
    @Test                         // IF I COMMENT THE @Test ANNOTATION AND 
    public void testMethod() {    // ALSO THE testMethod() THERE IS NO EXCEPTION
    }
}

感谢您提出任何建议......

我知道这是一个老问题，但在更改其他依赖项后，我最近得到了完全相同的错误。它似乎是javassist 3.18.2版本中的一个错误（我注意到你使用的是3.18.1）。

我通过将Powermock升级到版本1.6.2并明确添加对Javassist 3.19.0-GA的依赖来修复它。

此错误已在Javassist 3.18.2-GA中修复：https://issues.jboss.org/browse/JASSIST-223
