Pergunta
I am a beginner with erlang, and i write a basic gen server program as follows, I want to know, how to test the server so i can know it works well.
-module(gen_server_test).
-behaviour(gen_server).
-export([start_link/0]).
-export([alloc/0, free/1]).
-export([init/1, handle_call/3, handle_cast/2]).
start_link() ->
gen_server:start_link({local, gen_server_test}, ch3, [], []).
alloc() ->
gen_server:call(gen_server_test, alloc).
free(Ch) ->
gen_server:cast(gen_server_test, {free, Ch}).
init(_Args) ->
{ok, channels()}.
handle_call(alloc, _From, Chs) ->
{Ch, Chs2} = alloc(Chs),
{reply, Ch, Chs2}.
handle_cast({free, Ch}, Chs) ->
io:format(Ch),
io:format(Chs),
Chs2 = free(),
{noreply, Chs2}.
free() ->
io:format("free").
channels() ->
io:format("channels").
alloc(chs) ->
io:format("alloc chs").
BTW: The program can be compiled, and it is not a good program, I just want to print something to make sure it works :)
