Guide to importing jasmine testing functions in Angular 2 rc5

Recently I made the transition from rc4 to rc5 of Angular 2 for a new project. However, after upgrading, I noticed that functions like it, expect, describe, etc are no longer being exported from '@angular/core/testing'. Despite my thorough search across various resources, I have come across unit tests online claiming to use rc5 that still include these Jasmine test functions. Can someone guide me on where to import these functions from when using rc5? Could there be a new dependency library that I am overlooking?

package.json

"dependencies": {
  "@angular/common": "2.0.0-rc.5",
  "@angular/compiler": "2.0.0-rc.5",
  "@angular/core": "2.0.0-rc.5",
  "@angular/forms": "0.3.0",
  "@angular/http": "2.0.0-rc.5",
  "@angular/platform-browser": "2.0.0-rc.5",
  "@angular/platform-browser-dynamic": "2.0.0-rc.5",
  "@angular/router": "3.0.0-alpha.7",
  "@angular/router-deprecated": "2.0.0-rc.2",
  "@angular/upgrade": "2.0.0-rc.5",
... (remaining content unchanged)... 
}

Answer №1

Jasmine functions are now globally available in testing modules starting from RC4, eliminating the need for importing them from external sources.

Importing Jasmine functions from @angular/core/testing is no longer required and has been marked as deprecated.

For more information, refer to the final bullet point in the RC4 Changelog's Breaking Changes section.
