What steps will reproduce the problem? 1. Create a test with e.g.

self.mox = mox.Mox() self.mox.StubOutWithMock(module_under_test.logging, 'info') ...

other code that doesn't use module.logging

... self.mox.UnsetStubs()

2. Run the test

What is the expected output? What do you see instead?

I would expect the UnsetStubs call (probably in a tearDown method or similar) to return module_under_test.logging to its original state. Instead, all my other tests start failing.

Inserting the line: module_under_test.logging.info(mox.IsA(str) just after StubOutWithMock causes the issue to disappear.

What version of the product are you using? On what operating system?

Please provide any additional information below.

Hm, I'm unable to reproduce this with a simple example. What errors are you getting from your other tests? Are you sure that you are always calling UnsetStubs? Can you create a small example that reproduces this?

Attached as is a simple module under test, and some tests that pass.
