Center node: "configuration testing testing configuration values as code and with code"
  Abstract: This paper proposes configuration testing--evaluating configuration values (to be deployed) by exercising the code that uses the values and assessing the corresponding program behavior. We advocate that configuration values should be systematically tested like software code and that configuration testing should be a key reliability engineering practice for preventing misconfigurations from production deployment.  The essential advantage of configuration testing is to put the configuration values (to be deployed) in the context of the target software program under test. In this way, the dynamic effects of configuration values and the impact of configuration changes can be observed during testing. Configuration testing overcomes the fundamental limitations of de facto approaches to combatting misconfigurations, namely configuration validation and software testing--the former is disconnected from code logic and semantics, while the latter can hardly cover all possible configuration values and their combinations. Our preliminary results show the effectiveness of configuration testing in capturing real-world misconfigurations.  We present the principles of writing new configuration tests and the promises of retrofitting existing software tests to be configuration tests. We discuss new adequacy and quality metrics for configuration testing. We also explore regression testing techniques to enable incremental configuration testing during continuous integration and deployment in modern software systems.
