Summary: I'm working on deploying haste2 with jest. This updates all the files that require changes for this to work and they are backwards compatible with the current version of jest. * package.json was just outdated. I think haste1's liberal handling with collisions made this a "non-issue" * env.js didn't properly set up ErrorUtils, also unsure why that isn't a problem in jest right now already? * some things were mocking things they shouldn't * Because of the regex that matches against providesModule and System.import, it isn't possible to list module names more than once. We have multiple tests reusing the same providesModule ids and using System.import with modules that only exist virtually within that test. Splitting up the strings makes the regexes work (we do the same kind of splitting on www sometimes if we need to) and using different providesModule names in different test files fixes the problem. I think the BundlesLayoutIntegration-test is going to be deleted, so this doesn't even matter. public Reviewed By: voideanvalue Differential Revision: D2809681 fb-gh-sync-id: 8fe6ed8b5a1be28ba141e9001de143e502693281
