The test using \removepunctuation that you provided does what it should 
be doing (it produces 6 instances of "test-test" with the intervening 
punctuation mark in each case removed), but it doesn't do what I'm 
trying to do in the MWE above. I'm trying to take certain punctuation 
marks that follow the \autopuncttest macro and place them before it 
instead. Looking at the typo-chr .lua and .mkiv files, I see that there 
are \pushpunctuation and \poppunctuationmethods in addition to the 
\removepunctuation method. These might be useful for this purpose, but 
in any case, I still have to check if the trailing character is one of 
the characters in a specified set/string, and this is where the error is 
arising.
maybe you're in protected mode

% assumes \protect earlier

\unprotect
\def\autopuncttest#1#2{%
   \removeunwantedspaces%
   \doifinstring{#2}{,.!?;:}{#2}%
   \footnote{#1}%
   \doifnotinstring{#2}{,.!?;:}{#2}%
}
\protect

% assumes \unprotect later

or something

\pushcatcodetable \setcatcodetable\ctxcatcodes

\def\autopuncttest#1#2{%
   \removeunwantedspaces%
   \doifinstring{#2}{,.!?;:}{#2}%
   \footnote{#1}%
   \doifnotinstring{#2}{,.!?;:}{#2}%
}

\popcatcodetable
