Hi All I'm new to Angular2 and am struggling with the basics. I have a simple component and I thought it would be sensible to write a unit test. I followed the Twain example <https://angular.io/docs/ts/latest/testing/#!#component-with-async-service> which is very similar to what I am trying to achieve. The issue is that whenever I include my test spec I see the error:
Chromium 52.0.2743 (Ubuntu 0.0.0) ClientLogoCarouselComponent encountered a declaration exception FAILED Error: Cannot call Promise.then from within a sync test. at SyncTestZoneSpec.onScheduleTask (webpack:///home/matthew/Projects/cf/~/zone.js/dist/sync-test.js:11:0 <- src/test.ts:24070:27) at ZoneDelegate.scheduleTask (webpack:///home/matthew/Projects/cf/~/zone.js/dist/zone.js:202:0 <- src/test.ts:46485:49) at Zone.scheduleMicroTask (webpack:///home/matthew/Projects/cf/~/zone.js/dist/zone.js:139:0 <- src/test.ts:46422:39) at scheduleResolveOrReject (webpack:///home/matthew/Projects/cf/~/zone.js/dist/zone.js:449:0 <- src/test.ts:46732:14) at ZoneAwarePromise.then (webpack:///home/matthew/Projects/cf/~/zone.js/dist/zone.js:525:0 <- src/test.ts:46808:17) at new ApplicationInitStatus (webpack:///home/matthew/Projects/cf/~/@angular/core/src/application_init.js:33:0 <- src/test.ts:9491:60) at NgModuleInjector.DynamicTestModuleInjector.createInternal (DynamicTestModule.ngfactory.js:133:36) at NgModuleInjector.create (webpack:///home/matthew/Projects/cf/~/@angular/core/src/linker/ng_module_factory.js:88:53 <- src/test.ts:17465:76) at NgModuleFactory.create (webpack:///home/matthew/Projects/cf/~/@angular/core/src/linker/ng_module_factory.js:73:0 <- src/test.ts:17450:18) at TestBed._initIfNeeded (webpack:///home/matthew/Projects/cf/~/@angular/core/bundles/core-testing.umd.js:1072:0 <- src/test.ts:5230:68) I have setup my new project with Angular cli (1.0.0-beta.14; node: 6.4.0). I run the test suite with 'ng test' If I comment out 'client-logo-carousel.component.spec.ts' then the Twain test example runs fine in my project. The stacktrace refers to test.ts which must somehow be the source of the problem. I've included that in the plunkr. I am stuck here so I hope someone can offer some guidance.
