             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 sqlDate:java.sql.Date\n bigInt:java.math.BigInteger\n bigDecimalKeepItNull:java.math.BigDecimal\n intVal:java.math.BigInteger\n scale:int\n scalaBigInt:scala.math.BigInt\n bigInteger:java.math.BigInteger\n mixed:java.util.List\n makeMeGeneric:org.apache.flink.test.operators.util.CollectionDataSets$PojoWithDateAndEnum\n group:java.lang.String\n date:java.util.Date\n cat:org.apache.flink.test.operators.util.CollectionDataSets$Category (is enum)\n" but: was "GenericTypeInfo (PojoWithCollectionGeneric)\n key:int\n bigDecimalKeepItNull:java.math.BigDecimal\n intVal:java.math.BigInteger\n scale:int\n bigInt:java.math.BigInteger\n sqlDate:java.sql.Date\n pojos:java.util.List\n scalaBigInt:scala.math.BigInt\n bigInteger:java.math.BigInteger\n makeMeGeneric:org.apache.flink.test.operators.util.CollectionDataSets$PojoWithDateAndEnum\n date:java.util.Date\n cat:org.apache.flink.test.operators.util.CollectionDataSets$Category (is enum)\n group:java.lang.String\n mixed:java.util.List\n"   {code}
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_
