E2E CI tests are suffering from non-deterministic failures

[DiForss]

Our end-to-end continuous integration (E2E CI) tests are experiencing issues with non-deterministic failures. In other words, our automated tests are sometimes failing unpredictably, making it challenging to identify and address the root cause effectively.

To tackle this problem, we need to implement strategies to enhance the reliability and stability of our tests. Firstly, we should review our test environment setup to ensure consistency across runs. This involves verifying that all dependencies, configurations, and external services are properly managed and maintained.

Additionally, we should investigate potential race conditions or timing issues within our test suite. This may involve introducing synchronization mechanisms or adjusting timeouts to mitigate the impact of concurrent operations.

Furthermore, enhancing logging and error reporting mechanisms can provide valuable insights into the nature of these non-deterministic failures. By capturing more detailed information about test execution, we can facilitate easier diagnosis and troubleshooting.

Regularly reviewing and updating our test cases to account for changes in the application's behavior or environment is also essential. This proactive approach can help prevent unexpected failures caused by outdated or inaccurate tests.

Finally, establishing clear guidelines and best practices for writing and maintaining E2E tests can promote consistency and reliability across the team. Encouraging collaboration and knowledge sharing can also facilitate the discovery and resolution of issues related to non-deterministic test failures.

By implementing these strategies and fostering a culture of quality and continuous improvement, we can minimize the impact of non-deterministic failures on our E2E CI tests and ensure the reliability of our software delivery pipeline.
