[erlang-questions] common test cleanup

[Joel Reymont]

Consider the following fragment…

end_per_testcase(pass_config, Config) ->
    {_, Config1} = ?config(saved_config, Config),
    true = ?config(pass_config, Config1).

pass_config(Config) ->
    {save_config, [{pass_config, true}|Config]}.

This results in a message "Could not find element saved_config in Config." and a crash.

Is there no way to modify the Config in the test function and pass it to end_per_testcase?

	Thanks, Joel
