Effective probes to measure your test data

During this session I will discuss the benefits of integrating test data integrity monitoring in your ci/cd deployment implementation pipeline.

I will argue and motivate that in order to make a correct assessment of the validity of information retrieved from monitoring sources continuous validation of data integrity is required. Another topic involves the question whether or not search-based software engineering (SBSE) methods can (re)-position test probes to identify data integrity issues.

Together we will look at cases where problem-specific fitness functions can find optimal matching test data references to be used in a risk-based test approach from a potentially infinite number of data sources.

This session will take a pragmatic and empiric angle to address multiple qualitative statements regarding the hypothetical system state of the software under test based on information obtained from various monitoring/analytic sources that are commonly in place within an enterprise level IT landscape in 2020.

You will learn:
• how (infrastructure) testing probes can support a data-driven risk-based test strategy
• apply data that contributes to your adaptive testing strategy by recognizing and correlating deviations and anomalies
• new perspectives on data quality / data integrity
• new ways to improve your data quality monitoring
