I would think that you should be able to enter in the program, then use a basic disassembly (or listing) to confirm that the disassembled version matches up.  This won't catch everything, but it could at least call out any tokenization issues.

A long while back I started implementing an applesoft grammar parser, with the hope of going beyond that.  Though I didn't implement a tokenizer, I did write a disassembler that can take a binary basic file and render it back to ascii text.  The code for this is buried in the jace.appelesoft package of the JACE codebase -- and it's what I used to disassemble lemonade stand and convert everything to lowercase.  For retokenization, I'm currently going the slow route: Copy all to clipboard and then from the basic prompt press ctrl+ins to paste it in line by line for applesoft interpretation.  Not exactly ideal, but a start...
