Accumulation of memory usage in tests

[borkdude]

Most namespaces use lazy seq and delays or memoized functions at the top level. This accumulates used memory and eventually causes problems for the later tests.

One approach to solve this could be: delete the namespace after the last test using a global fixture.

Something like this for the JVM might work:

(run! #(alter-var-root % (fn [_] nil)) (vals (ns-publics 'aoc.y2018.d01.borkdude)))

For CLJS the following might work:

(gobject/remove (goog.getObjectByName (munge (namespace sym))) (munge (name sym)))

Under :advanced namespaces and vars get flattened. For example, with :pseudo-names true, aoc.y2018.d05.mfikes/part-2 gets flattened to $aoc$y2018$d05$mfikes$part_2$$.

The vars themselves still exists as separate objects. So for example the attached tests end up looking like:

$aoc$y2018$d05$mfikes$part_2$$.$cljs$lang$test$

The trick would be to somehow find the vars retaining data. (I don't think there is a way to remove an entire namespace.)

Closing because running all the tests is not necessary anymore for comparing test timings.
