By default, failed tests will clean up any temporary directories they created. Sometimes when debugging a failed test, it can be more helpful to leave the directory behind for further manual inspection.
Setting the environment variable ICTEST_SKIP_FAILURE_CLEANUP to any non-empty value
will cause the test to skip deletion of the temporary directories.
Any tests that fail and skip cleanup will log a message like
Not removing temporary directory for test at: /tmp/....
Test authors must use
interchaintest.TempDir
instead of (*testing.T).Cleanup to opt in to this behavior.
By default, Docker volumes associated with tests are cleaned up at the end of each test run.
That same ICTEST_SKIP_FAILURE_CLEANUP controls whether the volumes associated with failed tests are pruned.
