test phase fails in Mockito on Java 11 #262
Comments
|
I stand corrected. On the same platform as above, but using mockito 4.0.0, I received a different failure: [1018 11:23:37,483] INFO - CommunicationManager - BitTorrent client signing off. Results : Failed tests: testThatTorrentsHaveLazyInitAndRemovingAfterDownload(com.turn.ttorrent.client.CommunicationManagerTest): Torrent was not successfully initialized expected [true] but found [false] Note the timestamps, indicating that the last test took almost 4 minutes to run without any output until it started flooding output again. |
When compiling ttorrent on Mac OS X with Java 11, the build fails at the default-test phase with the following error:
setUp(com.turn.ttorrent.network.keyProcessors.CleanupKeyProcessorTest) Time elapsed: 482 sec <<< FAILURE!
org.mockito.exceptions.base.MockitoException:
Mockito cannot mock this class: interface com.turn.ttorrent.network.ConnectionListener.
Mockito can only mock non-private & non-final classes.
If you're not sure why you're getting this error, please report to the mailing list.

Presumably, this is due to the module feature introduced in Java 9 to make it harder to probe other module's code that is not officially exposed as an API. Are there plans to upgrade to a newer version of mockito that can deal with this issue? I tried hacking the pom.xml file to use mockito 4.0.0 and the build succeeded.
