如何在Angular2 rc5中导入茉莉花测试功能

Question

I am working on a new project and just upgraded from rc4 to rc5 of Angular 2. Upon upgrading it appears that functions like it, expect, describe, etc are no longer being exported from '@angular/core/testing'. I have searched every resource I can think of and I see unit tests written online that claim to be using rc5 that still have these Jasmine test functions. Where do you import these from using rc5? Is there a new dependency library that I'm missing?

package.json

They no longer need to be imported from anywhere as of RC4. They're made available globally to any testing module.

Importing Jasmine functions from @angular/core/testing is no longer necessary and is now deprecated.
