[Bug]: Heap OOM when combining `repeatEach` with `on-first-retry` and `retain-on-first-failure` trace configs
Version
1.50.1
Steps to reproduce
On a large test suite with many failing tests, config:
-
repeatEach= 3 -
retries= 2 -
traceconfig to eitheron-first-retryorretain-on-first-failure.
In these configs, after the tests complete, before the reporters complete, I encounter the below OOM.
Interestingly, setting the trace config to retain-on-failure solves it for me. Unfortunately, that leaves me with way too many unnecessary trace files.
Expected behavior
I would expect "on first failure" and "on first retry" to be the less memory intensive options...
Actual behavior
yet somehow they cause the heap OOM exception, while "retain on failure" doesn't.
