If you define a function, it is a good practice to test it with all invalid, extreme and many random normal parameter values. To facilitate this I wrote the simple TEST function, with the first parameter A_LineNumber, and the second parameter the expression I want to evaluate. The function reads the source file, removes the beginning and end of the line containing the expression and shows the expression and its value in a MsgBox, with the ErrorLevel after the expression got evaluated. I usually copy the text "TEST(A_LineNumber,)" into my private clipboard and insert it wherever the test cases appear in the script. Then I write the expression to be tested after the comma. It needs AHK version 1.0.31.05+

I like your idea. That is brilliant. It gives a nice overview of what the fuction can do (it limits).

I moded you code and my suggestion would be something like this:


If it worked, this script would be more flexible (for functions with not pipe delimitered parameters), and is gives you the returnvalue not the private variable "x". The problem I have is that I can't call the function via a variable, see comment in code.

You are right, toralf! If we had indirect function calls, everything would be easier. [Chris, is it planned?] Even now your idea works:You have to write the ValuesToTest and to copy the 2 lines of the loop to the place of testing. Replace the 2 function names inside the loop. If there are many test cases with constants, this solution is shorter. However, another level of indirection is necessary if the ValuesToTest are expressions:Expressions are not evaluated dynamically. It would be another desirable feature.
Schöne Idee!

It's on the to-do list but it might be a while in coming since it seems far less useful than dynamic variables.

That feature was omitted for performance and code complexity reasons. It might get added someday but probably only after the previous idea.

Thanks for the ideas.
