This is usually created automatically by Injector.resolveAndCreate.

It can be created manually, as follows:

Example

var resolvedProviders = Injector.resolve([{ provide: 'message', useValue: 'Hello' }]); var injector = Injector.fromResolvedProviders(resolvedProviders); expect(injector.get('message')).toEqual('Hello');
      
      var resolvedProviders = Injector.resolve([{ provide: 'message', useValue: 'Hello' }]);
var injector = Injector.fromResolvedProviders(resolvedProviders);

expect(injector.get('message')).toEqual('Hello');
