[riena-dev] Hunting bugs in unit test that depend on the extension registry
|
Hi,
We have several unit tests testing components that rely on the extension
registry.
The tests can add extensions/extension points via a "plugin.xml" and
remove them by their id - somehow asymmetric but the IExtensionRegistry
does yet not over a better API for this use case.
The problem that we see is that tests succeed when run locally within
Eclipse as a JUnit-Plugin test but fail when run in Hudson. It seems
that the extension registry behaves differently.
To track down the problems I have committed an ExtensionRegistryAnalyzer
which can dump the registry to system.out for manual inspection and can
provide snapshots of the registry which can be compared against.
The comparison of the after/before snapshots is made for each unit test
to check whether a test does not restore the registry properly which
could cause unwanted effects for other tests.
Tschüß,
Stefan
