Another way to do this, not necessarily better or more readable...

ALL_TESTS=,${ALL_TESTS},
for TEST in ${BLACKLISTED_TESTS}
do
  ALL_TESTS=${ALL_TESTS/,${TEST},/,}
done
ALL_TESTS=${ALL_TESTS/#,/}
ALL_TESTS=${ALL_TESTS/%,/}

+  do
+    ALL_TESTS=${ALL_TESTS/#${TEST},/}     # match first test (test,...)
+    ALL_TESTS=${ALL_TESTS/,${TEST},/,}    # match middle tests (...,test,...)
+    ALL_TESTS=${ALL_TESTS/%,${TEST}/}     # match last test (...,test)
+  done
