[tycho-dev] Please help with (test) code migration
|
Hi Tycho-Devs,
a lot of code from the OSGi part (that is under tycho-bundles) has been
now moved to the 'org.eclipse.tycho.core.shared' mixed maven-module/OSGi
bundle.
That means, everything under org.eclipse.tycho.core.shared can now be
used in both "worlds".
I'll plan to migrate the remaining parts as well into plexus components
so we hopefully can once drop all the "bundles" part of Tycho and fully
build everything as a plain maven codes.
As converting them to components is actually quite straight-forward the
tricky (and often very time consuming) part is often migrating the tests
into either plain JUnit or TychoPlexus tests.
It would therefore be highly appreciated and I'd like to encourage
everyone to help with migrating of those "low-hanging-fruits" tests that
actually not require anything from the not migrated parts.
The steps are usually as follows:
1) Just browse the code-base under tycho-bundles/*.tests and pick a
class that seems promissing, for example 'FileSetTest'
2) move the test to 'tycho-core' into a package that seems suitable (or
create a new one), in the best thats it, if not maybe some adjustments
are required.
3) possibly adapt the code and maybe one needs to copy/adapt some helper
classes from org.eclipse.tycho.test.utils > tycho-testing-harness or
copy some test-data to the new place as well.
4) If your test needs something that previously was looked up by OSGi
and is now already available in "maven", you can extend the
TychoPlexusTestCase and look them up with the lookup(...) method, an
example can be found in VerifierServiceImplTest and
MetadataSerializableImplTest
If encountering problems feel free to ask or just search for a
lower-hanging-fruit :-)
