----------------------------------------
Summary: Unable to run many tests in single tdml suite without
large amounts of memory
Key: DAFFODIL-2901
URL: https://issues.apache.org/jira/browse/DAFFODIL-2901
Project: Daffodil
Issue Type: Bug
Components: TDML Runner
Affects Versions: 3.7.0
Reporter: Olabusayo Kilo
The test suite I'm working with contains 600+ tests, and run just fine in
IntelliJ (which has a heap size of 4G), but fails to run with `sbt test`
failing with an out of memory error. This error doesn't go away until we
increase the sbt heap size to 8G. Then the tests run successfully.
Obvious workaround is just to do `sbt -mem 8192 test`, but it would be ideal if
this wasn't necessary, especially since the tests are run sequentially and not
in parallel. A memory leak in the runner seems like a likely suspect.
We would obviously need to profile an `sbt test` run using either JProfiler or
Intellij's built in profiler. Example schemas with lots of tests are the JREAP
schema and the P8 schema.
According to [~jadams_tresys] , this issue doesn't occur if the tests are split
out into multiple test suites
