1. 1Write unit tests for individual components using a testing framework like Jest or Pytest
2. 2Design system tests to cover end-to-end workflows and integrations
3. 3Use AI code assistants to generate test cases and identify potential bugs
4. 4Run unit tests and system tests in parallel to ensure comprehensive coverage
5. 5Analyze test results and refine testing strategies accordingly

Software development teams, especially those using AI code assistants, can benefit from understanding the differences between unit testing and system testing to ensure high-quality code

💡 Unit testing focuses on individual components, while system testing covers end-to-end workflows and integrations
