[Merge] lp:~wgrant/launchpad/trim-bugtask-search-tests into lp:launchpad
William Grant has proposed merging lp:~wgrant/launchpad/trim-bugtask-search-tests into lp:launchpad.
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
For more details, see:
https://code.launchpad.net/~wgrant/launchpad/trim-bugtask-search-tests/+merge/102628
test_bugtask_search currently multiplies most of its tests across three dimensions: target type (Product, Distribution, etc.), result type (preloaded BugTasks, not preloaded BugTasks, or Bug.id), and implementation (legacy or BugTaskFlat). The last is temporary, but the others are permanent. The tests currently take half an hour to run on modern hardware.
This branch cuts the number of effective tests by nearly 2/3, and most of the eliminated tests are the slow ones (Distribution, DistributionSourcePackage and SourcePackage tests have high setup times). Instead of multiplying all the tests by target, only those which have some change of being target-dependent are run for each. The rest are just run against Product. This should reduce the runtime to around 5 minutes once BugTaskFlat rules over all.
