---------------------------------
Summary: Fix Test Failures
Key: FLINK-33430
URL: https://issues.apache.org/jira/browse/FLINK-33430
Project: Flink
Issue Type: Bug
Reporter: Yang Chen
This issue is to fix test failures caused by flakiness.
Steps to reproduce test failures:
1)Run the following commands
{{}}
{code:java}
{code}
{{mvn -pl flink-tests edu.illinois:nondex-maven-plugin:2.1.1:nondex
-Dtest=org.apache.flink.test.misc.GenericTypeInfoTest#testSerializerTree}}
2) Then we found the following test failures:
{{}}
{code:java}
[ERROR] GenericTypeInfoTest.testSerializerTree:53 Expected: "GenericTypeInfo
(PojoWithCollectionGeneric)\n pojos:java.util.List\n key:int\n

cat:org.apache.flink.test.operators.util.CollectionDataSets$Category (is

The root cause of the test failure is due to assuming a consistent order of
{{{}serTree{}}}, but the elements of it are actually not consistent, to fix the
test failure:
_change the assertion to compare two lists, which can ignore the orders of
elements_
