Abstract: Machine learning is used for pre-submit test selection. A commit including a new code change is obtained and a feature vector is generated based on the code change and historical test information. A ranking pre-submit tests is determined by providing the feature vector to a learning algorithm. One or more pre-submit tests are selected based on the ranking and the new code change is tested using selected tests. An assessment of the new code change is determined based on the test results, which indicate whether the new code change is accepted or rejected for submission to the source code repository. Later, new submitted source code stored in the repository is tested using a set of post-submit tests to obtain post-submit test results. Then the learning algorithm is updated based on the assessment of the new code change and the post-submit test results to obtain an updated learning algorithm.
