我有以下模块
-module(bhavcopy_downloader).
-export([download/2]).
download(From, SaveTo) ->
{ok, {{Status, _}, _, Body}} = lhttpc:request(From, "GET", [], infinity),
case Status of
200 -> file:write(SaveTo, Body),
true;
_ -> false
end.
并对上述代码进行以下测试
file_download_test_() ->
{foreach,
fun() ->
meck:new(lhttpc)
meck:new(file, [unstick])
end,
fun(_) ->
meck:unload(file),
meck:unload(lhttpc)
end,
{"saves the file at specified location",
fun() ->
meck:expect(lhttpc, request, 4, {ok, {{200, "OK"}, [], <<"response">>}}),
meck:expect(file, write_file, fun(Path, Data) ->
?assertEqual(Path, "~/Downloads/data-downloader/test.html"),
?assertEqual(Data, <<"response">>)
end),
?assertEqual(true, bhavcopy_downloader:download("http://google.com", "~/Downloads/data-downloader/test.html")),
?assert(meck:validate(file))
end}]
}.
当我运行测试时,我得到以下错误(为简洁起见,下面仅粘贴了部分错误)。查看下面的错误,我感觉文件模块没有被模拟(或者当我使用 设置另一个模拟时文件模块的模拟被覆盖meck:new(lhttpc)
。这里可能出了什么问题?
