Here is a patch which refactors test_zipfile, decreases it's size by 269 lines, makes adding tests for new compression types and new tests for all compression types simpler, and makes test_zipfile discoverable.

As I understand this, the main refactoring is to put the tests duplicated for zlib, bz2, and lzma into a master class that is then subclasses=d for each of the compressors. This looks like a great idea.

Yes, the first patch includes only this change (plus some needed regrouping and renaming). The second patch in additional wraps long lines, uses asserts with better error reporting, has better resource management ("with" operator and addCleanup), and contains other minor changes (see a difference between two patches).

If there are no objection I'm going to commit this patch soon.

Thank you Terry for review. Here is updated patch addressed Terry's comments. Now random datas for tests generated once per class (generating them once per module will be more cumbersome and will save less time). Arguments for now generated from a special generator. This simplifies the code and makes possible to determine with what argument test is failed. I don't think subtest() is appropriate here (in any case it is 3.4 only).

When applying first Terry's suggestion I found a bug. self.list_gen was a generator and when self.list_gen used second time it was exhausted. As result, some tests were skipped and a bug with concatenating bytes and '\n' was not exposed.

This bug should be fixed in 2.7 if it exists.
