Flaky tests, those that pass and fail intermittently without code changes, are a frequent source of frustration. They waste valuable developer time and erode confidence in the reliability of the checks themselves.

• Possible Causes: Network instability, timing discrepancies, dependencies on external services, or inconsistent test data can all contribute to flaky tests.
• Solutions: Isolate and quarantine flaky tests. Investigate the root cause and implement a fix. Consider using retry mechanisms in your Continuous Integration (CI) configuration to handle transient failures.
• Prevention: Write deterministic tests, mock external dependencies, and use robust test data management practices.

Timeout Issues

Resource-intensive checks, such as complex builds or extensive test suites, can sometimes exceed allocated time limits, resulting in timeouts. This halts the entire pipeline and can block merges.

• Possible Causes: Insufficient resources allocated to the CI runner, inefficient build processes, or long-running tests are potential culprits.
• Solutions: Increase timeout limits in your check configuration. Optimize your build processes and break down large tests into smaller, more manageable units. Consider using more powerful CI runners with increased resources.
• Prevention: Continuously monitor check execution times and proactively identify slow or resource-intensive checks. Optimize resource allocation based on the specific needs of each check.

Conflicts Between Check Services

Using multiple check services can sometimes lead to conflicts, particularly if they attempt to modify the same files or access shared resources. This can cause unpredictable check behavior and failed builds.

• Possible Causes: Overlapping functionalities of different check services, incompatible configurations, or resource contention can cause conflicts.
• Solutions: Clearly define the roles and responsibilities of each check service. Ensure their configurations are compatible and isolate their operations to prevent conflicts.
• Prevention: Carefully evaluate and select check services to avoid redundancy and potential conflicts. Establish a clear hierarchy for check execution to effectively manage dependencies.

Permission-Related Roadblocks

Checks can fail due to insufficient permissions to access required resources, such as repositories, secrets, or external systems. This often manifests as authentication errors or "access denied" messages.

• Possible Causes: Incorrectly configured access tokens, missing repository permissions, or improperly configured access control settings.
• Solutions: Review and update access tokens. Grant the necessary repository permissions to the CI user. Verify that access control settings are correctly configured.
• Prevention: Utilize fine-grained access control mechanisms to effectively manage permissions and implement a clear access policy for CI users. Regularly audit and update permissions to prevent future issues.
