David Capwell commented on CASSANDRA-15555:
-------------------------------------------
All examples above were called by running the following
{code}
ant testclasslist -Dtest.classlistfile=<(echo
org/apache/cassandra/transport/frame/checksum/ChecksummingTransformerTest.java)
-Dtest.classlistprefix=unit
{code}
In order to not timeout, I added -Dtest.timeout=60000000
> Lower the amount of garbage ChecksummingTransformerTest generates by reusing
> memory

> When the test finds a issue and attempts to shrink, a ton of garbage is
> generated which cause the test to then fail with GC issues. Since the test
> is a quick theories test, we can rewrite the generates to reuse memory rather
> than creating new objects for each iteration. This will also let us move
> away from String which requires multiple copies in the test and gets rid of
> the getBytes() call which is dependent on the system its called on.
