Properly testing an OTP application after initialization

[Max Lapshin]

I do not understand what fixtures are for.


We test our flussonic in this manner:


init_per_suite(Config) ->
  application:ensure_all_started(flussonic)
  Config.


test1(_) ->
 ....

test2(_) ->
  ...


end_per_suite(Config) ->
  application:stop(flussonic),
  Config.



Some tests are touch deep internals (we do not like it), some of them
are only using external TCP connections and could be written, for
example, in Python. We like them, but they are not stable.
