That perfectly suits my needs. I misnoticed the possibility for the "%unit:before" to be invoked before one single unit function. Thanks Christian for your fantastic product!

Dear BR dudzikp,

You can place your actual test your assertion in a second function with the %unit:after annotation. Another solution is to perform your update in a %unit:before function and test the result in the main function. See [1] for an example.

Cheers, CG

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?
