Abstract: Methods, system, and non-transitory processor-readable storage medium for a test selection system are provided herein. An example method includes selecting a regression test case from a plurality of regression test cases in a software testing lifecycle system. A test selection system calculates a score for the regression test case using an Analytic Hierarchy Process (AHP) assigned weight. Using the score, the test selection system visualizes a relationship between the regression test case and goals associated with a regression testing effort. The test selection system selects the regression test case for use in the regression testing effort based on the visualized relationship, and executes the regression test case on a system.

Abstract: Access permission is enabled. For example, in response to receiving an access request for a target file from a first client, a type of an access permission contained in the request is determined. Then, a first type of access permission is determined that can be assigned to the first client if it is determined that the contained type is in a set of reference types. Further, it may be determined that a second type of access permission applicable to be assigned to the target file. It can then be determined, from the first type and the second type, a target type of an access permission to be assigned to the first client. As a result, the probability of assigned access permissions being interrupted can be reduced, the performance of a client and a server is increased, efficiency is increased, and the user experience is improved.

Abstract: Embodiments of the present disclosure provide a method for resource recovery, an electronic device, and a program product. The method may include determining a first association relation between a first quantity of a to-be-used resource in a system and time. The method may further include determining a second association relation between a second quantity of the to-be-recovered resource in the system and time on the basis of a plurality of received resource recovery tasks. In addition, the method may include changing the second association relation by adjusting a recovery sequence of the plurality of resource recovery tasks so as to reduce a difference between the first association relation and the second association relation within a predetermined period. Further, the method may include executing the plurality of resource recovery tasks on the basis of the adjusted recovery sequence.
