From 603fe0d19608ffe1915d8bc23bf412912e7ee1ac Mon Sep 17 00:00:00 2001 From: Julie Date: Thu, 21 Feb 2013 11:55:16 -0800 Subject: feat(angular.bootstrap): support deferred bootstrap This features enables tools like Batarang and test runners to hook into angular's bootstrap process and sneak in more modules into the DI registry which can replace or augment DI services for the purpose of instrumentation or mocking out heavy dependencies. If window.name contains prefix NG_DEFER_BOOTSTRAP! when angular.bootstrap is called, the bootstrap process will be paused until angular.resumeBootstrap is called. angular.resumeBootstrap takes an optional array of modules that should be added to the original list of modules that the app was about to be bootstrapped with. --- test/AngularSpec.js | 74 ++++++++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 73 insertions(+), 1 deletion(-) (limited to 'test/AngularSpec.js') diff --git a/test/AngularSpec.js b/test/AngularSpec.js index cc752b6c..7f1ab8a3 100644 --- a/test/AngularSpec.js +++ b/test/AngularSpec.js @@ -658,7 +658,7 @@ describe('angular', function() { var element = jqLite('
