This research addresses the critical issue of performance regression in continuous integration, optimizing the process to reduce infrastructure costs and improve timely diagnostics, crucial for rapid software development cycles.
To productize, develop a SaaS solution that integrates with popular CI systems like Jenkins or GitHub Actions. Offer features like risk scoring, test batch optimization, and detailed analytics.
This approach could replace traditional batch testing strategies that lack dynamic risk awareness, making software releases faster and more reliable by decreasing CI-associated regressions without increasing costs.
The market includes large software companies spending heavily on CI infrastructure, such as Mozilla, Google, and Facebook. They need cost-effective ways to manage testing resources, making them potential customers willing to pay for optimization tools.
A commercial tool for DevOps teams that implements risk-aware batch testing in CI workflows to cut costs and improve regression detection speed.
The paper presents a method integrating machine-learned performance regression risk with adaptive batch testing in CI systems. It employs ML models like CodeBERT to predict the likelihood of performance regressions at the commit level, guiding the prioritization and grouping of commits for testing purposes.
The approach was tested using a real-world Mozilla dataset, with risk models predicting commit-level regressions based on historical data. Results showed significant reduction in test executions and infrastructure costs.
Risk predictions are only as good as the training data quality; poor implementation of unseen data might lead to inaccurate risk scores and potential delays in critical regression detection.
