Add GitHub Actions workflow to verify flaky test

[Md-Arif-Hasan]

Purpose

This PR adds a custom GitHub Actions workflow named verify-flaky-test.yml to confirm that the test org.jsmart.zerocode.core.kafka.DeliveryDetailsTest#testSerDeser is flaky. The test passes under normal execution but fails when executed with NonDex, confirming the presence of non-deterministic behavior.

Summary of Changes

• Added a new workflow .github/workflows/verify-flaky-test.yml
• The workflow:
  • Sets up JDK 11 using actions/setup-java
  • Builds the project using Maven with tests skipped
  • Runs the test once normally (expected to pass)
  • Runs the test again using NonDex (expected to fail)
  • Verifies flakiness by comparing exit codes and logs

Output

The GitHub Actions build shows:

• ✅ Normal test run passes
• ❌ NonDex test run fails
• ✅ Final verification logs include:
  ✅ Test is flaky: Passes without NonDex but fails with NonDex

You can find the logs and output in the attached file or view the successful build here:

Notes

This workflow documents the flakiness of DeliveryDetailsTest.testSerDeser using GitHub Actions.
The CI logs confirm that the test passes normally but fails under NonDex shuffling.
