Subject: Simplified tests for HeroService
X-Git-Url: http://juplo.de/gitweb/?p=examples%2Fangular-tour-of-heroes;a=commitdiff_plain;h=c2ce800fc99390d95d4cfcce93f597490f6a948b

Simplified tests for HeroService

* See: https://medium.com/netscape/testing-with-the-angular-httpclient-api-648203820712
* Note: error-handling is not needed here, because the errors
  (500 / 404) are handled in the service and the expected result
  is already tested.
