Hi, I am running a set of unit tests for a custom product nightly via a buildbot installation, via bin/zopectl test -s Products.MyProduct in zope 2.9. Sorry in advance that this looks complicated - my query is actually pretty straightforward! Recently, I introduced a bug in the __init__.py of the product, which caused the product installation to fail in zope. The following was written to stdout: 2007-04-12 10:05:34 ERROR Zope Couldn't install CMFMyProduct Traceback (most recent call last): File "/usr/local/Zope-2.9.5/lib/python/OFS/Application.py", line 783, in install_product initmethod(context) File "/home/buildslave/buildslaves/astrodon/build/Zope-2.9.5/Products/CMFMyProduct/__init__.py", line 227, in initialize context.registerClass(MyModule.MyClass, NameError: global name 'MyModule' is not defined The trivial error was that MyModule was not imported earlier in __init__.py However, having logged this, the testrunner proceeded to run all my tests correctly, and so the buildbot reported a pass. I expected the testrunner to bomb out on encountering this error, but it didn't - however if I start zope with zopectl fg, the bug I introduced causes it to fail to start. I'm a bit concerned that there was a false test pass. Is there a way to stop the testrunner in this case, in the same way as running in fg mode? Thanks, Miles
