Abstract

Described are techniques for predictive regression testing. The techniques include a method comprising constructing a call graph of a modified codebase including at least one modified node corresponding to a modified function. The method further comprises generating a subset of codebase tests by removing respective codebase tests that do not call for the at least one modified node. The method further comprises generating respective partial Abstract Syntax Trees (AST) sequences for relevant test paths in the call graph that connect the at least one modified node to one of the subset of codebase tests. The method further comprises inputting, to a machine learning model, the respective partial AST sequences, and generating, based on output from the machine learning model, predicted regression testing results for the relevant test paths.
