------------------------------------
Summary:
o.a.h.hdfs.server.blockmanagement.TestBlockManagerSafeMode.testCheckSafeMode
fails intermittently
Key: HDFS-10284
URL: https://issues.apache.org/jira/browse/HDFS-10284
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Affects Versions: 2.9.0
Reporter: Mingliang Liu
Assignee: Mingliang Liu
*Stacktrace*
{code}
org.mockito.exceptions.misusing.UnfinishedStubbingException:
Unfinished stubbing detected here:
-> at
org.apache.hadoop.hdfs.server.blockmanagement.TestBlockManagerSafeMode.testCheckSafeMode(TestBlockManagerSafeMode.java:169)
E.g. thenReturn() may be missing.
Examples of correct stubbing:
when(mock.isOk()).thenReturn(true);
when(mock.isOk()).thenThrow(exception);
doThrow(exception).when(mock).someVoidMethod();
Hints:
1. missing thenReturn()
2. although stubbed methods may return mocks, you cannot inline mock creation
(mock()) call inside a thenReturn method (see issue 53)
