<div dir="ltr"> Hi all, I attach this in case anyone thinks it might be useful. I don't mean to imply that Bazaar is inadequately tested but I thought this might be a useful addition to its current testing. It didn't take me long to produce it and I think you could easily produce a lot more of this kind of test quite quickly It makes use of TextTest which you can download from <a href="http://sourceforge.net/project/showfiles.php?group_id=80138">http://sourceforge.net/project/showfiles.php?group_id=80138</a> Further information lives at <a href="http://www.texttest.org">http://www.texttest.org</a>. (I'm currently in the process of migrating TextTest to use Bazaar and Launchpad.) Basic instructions: install PyGTK and tkdiff, unzip the attached test suite and the TextTest download, cd to the test suite directory and run texttest.py from wherever you unzipped it. The basic plan: it runs bazaar from the command line and compares stdout, stderr, a generated file describing all files created, edited and deleted, and the bazaar log. Run-dependent entries in these are filtered away. It also runs everything on copies of the data which are then removed so you don't have to reset anything. BZR_HOME, the bazaar repository .bzr, and the working tree are all test data and vary throughout the structure independently of one another. I've run it on bazaar 1.3.1 and 1.5 and the tests work unchanged between those versions. But the baseline files are easy to "save" as and when this is needed. The main points: 1) You don't need to know the code to write tests (I've never looked at the code) 2) Tests don't depend on the structure of the code and hence don't need changing when the code is refactored. 3) There are already quite a few blackbox tests that look like def test_update_standalone_trivial(self):         self.make_branch_and_tree('.')         out, err = self.run_bzr('update')         self.assertEqual('Tree is up to date at revision 0.\n', err)         self.assertEqual('', out) This is basically a way to write tests of that form without writing any code. Let me know if anyone is interested in trying this out. Am happy to provide further information if needed. Regards, Geoff Bache </div>
