我在工作场所刚刚'继承'了一个OTP项目，并且遇到以下问题： 一组测试包括调用使用os的函数： cmd，这似乎是测试失败的原因，这是我在失败和成功测试之间唯一的区别。我正在Mac OS X 10.6.8和Erlang 14A上运行测试。在Mac OSX中包含调用os：cmd失败的eurls 10.6
这些失败的功能：
execute_shell_command(Config, Event, Params, output) ->
execute_with_output(Config, Event, Params);
execute_shell_command(Config, Event, Params, status) ->
execute_with_status(Config, Event, Params).
execute_with_output(Config, Event, Params) ->
Command = executable(Config, Event),
String = string:join([Command|Params], " "),
error_logger:info_msg("Command to be invoked:~n~p", [String]),
os:cmd(String).
及以下的测试失败：
execute_with_output_test() ->
Config = [{click, [{log_path, "fixtures"}, {executable, "echo"}]},
{processing_stat_path, "fixtures"}],
?assertMatch("OK", execute_with_output(Config, click, ["-n", "OK"])).
execute_with_output_success_test() ->
Config = [{click, [{log_path, "fixtures"}, {executable, "true"}]},
{processing_stat_path, "fixtures"}],
?assertMatch("success", execute_with_output(Config, click,
[status_as_output_suffix()])).
execute_with_output_failure_test() ->
Config = [{click, [{log_path, "fixtures"}, {executable, "false"}]},
{processing_stat_path, "fixtures"}],
?assertMatch("error", execute_with_output(Config, click,
[status_as_output_suffix()])).
execute_with_status_success_test() ->
Config = [{click, [{log_path, "fixtures"}, {executable, "true"}]},
{processing_stat_path, "fixtures"}],
?assertMatch(ok, execute_with_status(Config, click, [])).
execute_with_status_failure_test() ->
Config = [{click, [{log_path, "fixtures"}, {executable, "false"}]},
{processing_stat_path, "fixtures"}],
?assertMatch(error, execute_with_status(Config, click, [])).
hdfs_put_command_parameters_echoed_test() ->
Config = [{click, [{log_path, "fixtures"},
{executable, "echo -n"},
{delete_after_copy, false},
{hdfs_url, "hdfs://localhost/unprocessed/clicks"}]},
{processing_stat_path, "fixtures"}],
{ok, Hostname} = inet:gethostname(),
Expected = "fs -put test_file hdfs://localhost/unprocessed/clicks/" ++ Hostname ++ "-test_file",
?assertMatch(Expected, hdfs_put_command(Config, click, "test_file", output)).
click_upload_success_test() ->
Config = [{click, [{log_path, "fixtures"},
{executable, "fixtures/hadoop_mock_success"},
{delete_after_copy, false},
{hdfs_url, "hdfs://testhost"}]},
{processing_state_path, "fixtures"}],
unconsult(configuration_file(test), Config),
Callback = click_upload(test),
?assertMatch([ok, ok], Callback(click, test_message)),
write_last_processed(Config, click, "click-2009-04-10-17-00").
测试套件的输出
