[basex-talk] testing of updating functions in basex

Dear all, I have not found a way to make basex unit module to test updating functions. I have a function site:add-movies which results in several db:add instructions. I try to achieve something like: declare %unit:test %updating function test-site:download-movies() {   let $result :=     site:add-movies(       $test-site:site-db,       test-site:fake-fetch-file#1,       7     )        return unit:assert-equals(1, 1)        (: here I am going to check if db contains expected elements :) }; But let command is not valid for updating expression. Basex docs mention something about update:output and update:cache which may be of some use here but no exhaustive example is given for. Anyone had similar problem? BR
