If I write string.find("test()","("), it give me the error "unfinished capture". Other Chars work. what can I do?

Because brackets are a special character in patterns you have to escape them.

("test()"):find "%("

Please do not forgot the brackets, because this is correct, but pretty dirty:

("test()"):find("%(");

or

string.find("test()", "%(");

That's "normal" Lua syntax. I don't see a reason why you should add brackets if you don't have to; You save time and space. In contrast, your code is "dirty": You are using semicola even though they have no "special" meaning in Lua. They are just there to comfort those who come from languages enforcing them so their habits won't break their code.
