Summary: Date related issue in unit test
VolatileComponentStatusRepositoryTest
Key: NIFI-6509
URL: https://issues.apache.org/jira/browse/NIFI-6509
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Tamas Palfy
Unit test
{{VolatileComponentStatusRepositoryTest.testFilterDatesUsingPreferredDataPoints}}
may fail with the following:
{code:java}
java.lang.AssertionError:
Expected :Thu Jan 01 00:00:00 CET 1970
Actual :Thu Jan 01 01:00:00 CET 1970
{code}
The test creates a {{VolatileComponentStatusRepository}} instance and adds
{{java.util.Date}} objects to it starting from epoch (via {{new Date(0)}}).
This first date at epoch is the _Actual_ in the _AssertionError_.
Then filters this list by looking for those that are earlier or matching a
_start_ paramater. This _start_ is created from a {{LocalDateTime}} at the
default system time zone.
This is the _Expected_ in the _AssertionError_.
In general the issue is the difference in how the list is created (dates that
are 00:00:00 GMT) and how the filter parameter date is created (00:00:00 at
system time zone).
