Introduction

What regressions have we had, and what was their causes?

• notest: we had no test for something that used to work (e.g. oversight, testing in layers, whatever). It does not imply that a test could reasonably have been predicted to be needed. Note that tests added in a patch don't count: regressions break existing behaviour, so any tests for that behaviour need to predate the breakage.
• badtest: We had a test but it didn't test well enough or some such. As with notest, note that tests added in the same branch as the regression really don't count. Such tests (broken or not) I would classify under notest.
• yuiupgrade: upgrading yui broke things (and we didn't notice)
• jsmigration: ajaxifying/jsifiying things didn't preserve pre-js behaviours.
• ops: The issue was outside Launchpad and we don't know the cause / leadup. May imply notest.
• unknown: The cause of the regression is not yet known.
• sideeffect: The regression was a sideeffect of some other change.
• bzrupgrade: The issue is because of a change in bzr.
• testdisabled: We had a test but it was disabled.
• integration: Breakage when things were integrated (e.g. version mismatches)
