Deep learning-powered test case prioritisation in continuous integration: a comparative study and efficiency analysis

The empirical study introduces a deep learning-based approach for prioritising test cases in continuous integration (CI) environments, leveraging historical CI data to optimise resource allocation and reduce testing time. The model achieved a remarkable 100% accuracy in prioritisation, outperforming traditional methods. Compared to decision tree, it achieved perfect accuracy with fewer test cases. Against random forest, it had a higher fault detection rate while maintaining efficiency. When compared to neural network, it struck a balance between fault detection and execution time. This research highlights deep learning's potential in transforming CI/CD testing strategies and software development practices.
