My development style for bzr-svn is basically like this:

 * Determine new behaviour that is needed
 * Write a couple of tests that test whether this behaviour is present
(simple as well as some more advanced tests that cover corner cases)
 * Implement feature until all tests pass
 * Test on "real world" repositories, maybe extend the testsuite a bit
more if I see more corner cases

If somebody has a bug that I can reproduce, I export BZR_PDB=pdb2.5 and
then run bzr with the command that is failing. I then try to add a
minimal subset of code that reproduces the bug and then fix the code to
make that test pass.

Hope this helps,

Cheers,

Jelmer
