The spec helper files here set up the global testing environment prior to the execution of specs.
There are 3 options:
- init_node_spec- configures a node environment to test Angular applications with platform-server.
- init_node_no_angular_spec- configures a node environment for testing without setting up Angular's testbed (no dependency on Angular packages is incurred).
- init_browser_spec- configures a browser environment to test Angular applications.
