Abstract: Methods, system, and non-transitory processor-readable storage medium for code path test selection system are provided herein. An example method includes the code path test selection system defining a multi-level test coverage target based on code paths associated with a plurality of test cases, where the multi-levels correspond to different test hit rates. The code path test selection system generates a test target code path vector representing code paths to be tested, comprising vector elements weighted based on importance of the corresponding code paths and generates test case code path vectors representing code paths covered by the plurality of test cases. The code path test selection system selects a set of test cases from the plurality of test cases based on the test case code path vector and the test target code path vector. A CI/CD pipeline system executes the set of test cases on a test system.

Abstract: Methods, system, and non-transitory processor-readable storage medium for test correlation selection system are provided herein. An example method includes executing a plurality of test cases on a system. The test correlation selection system analyzes a correlation among the executed test cases by examining a result of the execution of the plurality of test cases to create a test case set correlation degree matrix. The test correlation selection system selects a subset of the plurality of test cases, based on the test case set correlation degree matrix, to execute on a test system to optimize test coverage of the plurality of test cases.

Abstract: Techniques perform data input and output. For example, there is provided a technique for updating a data pattern table. The technique involves: during a time period for establishing or updating the data pattern table: receiving a data write request; making statistics of a frequency of data being written; and writing data frequently used and an identification of the data to a corresponding entry of the data pattern table based on a result of the statistics. Using such a technique, a data pattern table can be customized and data storage efficiency can be improved.
