Imposteriser produces ClassCastException when JUnit tests are run with Ant.
--------------------------------------------------------------------------- Key: JMOCK-225 URL: http://jira.codehaus.org/browse/JMOCK-225 Project: jMock Issue Type: Bug Components: JMock 2.x.x Library Affects Versions: 2.5.1, 2.6.0 Environment: MacOS X 10.5, Ant via Eclipse Reporter: Richard Rothwell I am mocking Concrete classes using the standard Imposteriser.INSTANCE. The tests run fine under the Eclipse IDE. However when the same tests are run using the Ant JUnit task they fail with a ClassCastException. The condition required to reproduce this bug is to mock a concrete class (or its subclass) more than once over several test classes. Typically the first use of the Mock class succeeds, but subsequent Test classes using the same mocked concrete class fail. Commenting out the first usage will allow the second usage (which failed) to succeed. Debugging into the code seems to show CGLIBed instances of the expected class. The failure is in: public <T> T imposterise(final Invokable mockObject, Class<T> mockedType, Class<?>... ancilliaryTypes) { if (!mockedType.isInterface() && toStringMethodIsFinal(mockedType)) { throw new IllegalArgumentException(mockedType.getName() + " has a final toString method"); } try { setConstructorsAccessible(mockedType, true); Class<?> proxyClass = createProxyClass(mockedType, ancilliaryTypes); return mockedType.cast(createProxy(proxyClass, mockObject)); } finally { setConstructorsAccessible(mockedType, false); } } On this line: return mockedType.cast(createProxy(proxyClass, mockObject)); I have converted my own classes to use interfaces and removed imposteriser (using just interfaces with the imposteriser also fails). However I am now stuck because I am also mocking 3rd part classes. Any workarounds appreciated. P.S. I have upgraded from 2.5.1 to 2.6.o without improvement. P.P.S. I think this is running in the Ant JVM -- connected via remote socket debug. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |
