[jira] [Updated] (NIFI-10875) Test org.apache.nifi.processors.solr.TestQuerySolr.testAttributes Fails on NonDex
[ https://issues.apache.org/jira/browse/NIFI-10875?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yichen updated NIFI-10875:
--------------------------
External issue URL: https://github.com/apache/nifi/pull/6718
Description:
{code:java}
org.apache.nifi.processors.solr.TestQuerySolr.testAttributes {code}
This is a flaky test, it can pass mvn test while but when run using the tool [NonDex|https://github.com/TestingResearchIllinois/NonDex], it fails. NonDex is a tool that will introduce non-determinism in certain java collections.The test shows below:

*Steps to reproduce the failure:*
Run the following command in nifi:
First, build the module:
{code:java}
mvn install -pl nifi-nar-bundles/nifi-solr-bundle/nifi-solr-processors -am -DskipTests{code}
Then run the test using NonDex
{code:java}
mvn -pl nifi-nar-bundles/nifi-solr-bundle/nifi-solr-processors edu.illinois:nondex-maven-plugin:2.1:nondex -Dtest=org.apache.nifi.processors.solr.TestQuerySolr#testAttributes{code}
The result will be saved under the module folder in .nondex
The cause of this failure is when you set the property for test runner class, the order they are stored is non-deterministic, and when you convert it to a string, the result is different every time being called. The root cause of it is the use HashMap in the library code
{code:java}
org.apache.solr.common.params.ModifiableSolrParams{code}
We can't modify that library code, but we can modify the test such to ensure the actual result matches one of two expected string's permutations.

> *Steps to reproduce the failure:*
> Run the following command in nifi:
> First, build the module:
> {code:java}
> mvn install -pl nifi-nar-bundles/nifi-solr-bundle/nifi-solr-processors -am -DskipTests{code}
> Then run the test using NonDex
> {code:java}
> mvn -pl nifi-nar-bundles/nifi-solr-bundle/nifi-solr-processors edu.illinois:nondex-maven-plugin:2.1:nondex -Dtest=org.apache.nifi.processors.solr.TestQuerySolr#testAttributes{code}
> The result will be saved under the module folder in .nondex
> The cause of this failure is when you set the property for test runner class, the order they are stored is non-deterministic, and when you convert it to a string, the result is different every time being called. The root cause of it is the use HashMap in the library code
> {code:java}
> org.apache.solr.common.params.ModifiableSolrParams{code}
> We can't modify that library code, but we can modify the test such to ensure the actual result matches one of two expected string's permutations.
