Joseph Wu created MESOS-4872:
--------------------------------
Summary: Dump the contents of the sandbox when a test fails
Key: MESOS-4872
URL: https://issues.apache.org/jira/browse/MESOS-4872
Project: Mesos
Issue Type: Improvement
Components: test
Reporter: Joseph Wu
[~bernd-mesos] added this logic for extra info about a rare flaky test:
https://github.com/apache/mesos/blob/d26baee1f377aedb148ad04cc004bb38b85ee4f6/src/tests/fetcher_cache_tests.cpp#L249-L259
This information is useful regardless of the test type and should be
generalized for {{cluster::Slave}}. i.e.
# When a {{cluster::Slave}} is destructed, it can detect if the test has
failed.
# If so, navigate through its own {{work_dir}} and print sandboxes and/or other
useful debugging info.
Also see the refactor in [MESOS-4634].
