[jira] [Updated] (NIFI-10630) Fixed Possible Json Ordering Permutations Problem in Tests
[ https://issues.apache.org/jira/browse/NIFI-10630?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Boyu Li updated NIFI-10630:
---------------------------
Description:
The test file
{code:java}
nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors
org.apache.nifi.processors.standard.TestWaitNotifyProtocol
{code}
has flakiness with the below three tests.
{code:java}
testNotifyAttributes
testNotifyCounters
testNotifyFirst
{code}
The test flakiness is due to comparisons between Json Strings and outputs from
cacheEntry.getValue() which is an Object AtomicCacheEntry<String, String, Long>
However, JsonObject does not guarantee entry orders, its object is an unordered set of name/value pairs, and internal permutations may occur in the output as JSON String.
*Steps to reproduce the failure:*
The flakiness was found with [NonDex.|https://github.com/TestingResearchIllinois/NonDex)]
After installing NonDex and run the following code.
{code:java}
cd nifi
mvn install -pl nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors -am -DskipTests
mvn -pl nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors edu.illinois:nondex-
