🌟 Summary

Improvement of the GitHub test workflow with a more flexible configuration for retries.

📊 Key Changes

• Added a shell: python configuration to the retry action, allowing Python commands to be retried.
• Incorporated a retry_delay parameter of 5 seconds for immediate retry logic, and a 30 seconds delay for longer retries.
• Modified the test command to simulate a failure by using print(1/0) for better testing of the retry mechanism.

🎯 Purpose & Impact

• Enhanced Flexibility: By allowing Python commands and configurable retry delays, the workflow is more adaptable to different testing needs. 📈
• Better Testing Simulation: Simulating a failure with print(1/0) helps ensure the retry mechanism is robust and working as intended, improving overall reliability. 🚀
• User Impact: Users benefit from more reliable CI pipelines, ensuring that transient issues don't cause unnecessary build failures. ☑️
