[test] Replace PowerMockito#mockStatic usages with mockito-inline by nicoloboschi · Pull Request #14098 · apache/pulsar

nicoloboschi · 2022-02-02T23:27:11Z

Motivation

PowerMockito static mocks don't work well with the latest JDK class encapsulation mechanisms. The main problem is that PowerMockito, in order to mock a single static method of a class, try to setAccessible a lot of other apparently related classes. This means, starting from JDK17, you need to add --add-opens to the Java runtime options in order to avoid runtime errors.

PowerMockito development isn't much active and they don't seem to be ready for the new JDK releases.
The best replacement is to use mockito-inline (additional part of mockito-core), which uses a different algorithm in order to mock static methods - a lot less invasive.

Modifications

Replaced PowerMockito#mockStatic usages with MockedStatic
Added a Factory to NarClassLoader since it's not possible to mock ClassLoader classes in mockito-inline. The API for the NarClassLoader is internal so no problem changing it. See https://github.com/mockito/mockito/blob/main/src/main/java/org/mockito/internal/creation/bytebuddy/InlineDelegateByteBuddyMockMaker.java#L553

Great work.

I believe we have to rework that Factory class. I found it a bit unusual. I understand that it is for Mockito but we can probably organise it better

lhotari

did you try Mockito.mockStatic(NarClassLoader.class, Mockito.CALLS_REAL_METHODS) ? does that help address the limitation that you were describing about not being able to mock static methods on a classloader class?

nicoloboschi · 2022-02-08T22:50:21Z

@lhotari thanks for the suggestion. Unfortunately it doesn't help. I inspected the mockito-inline codebase and I haven't found a way to by-pass this check.

@nicoloboschi - it looks like the broker test is failing with the below stack trace. I'm wondering if it is a legitimate failure and not just a flaky test.

@michaeljmarshall yes you're right. I've found a couple of other tests that can't simply pass for the same reason (Required clusterName is null). I can't explain to myself how they can be green on current master. Maybe enabling `mockito-inline´ Mockito itself is more stable.

…est - don't know how they passed before
