A computing device selects a software application comprising application libraries each associated with a current version identifier. The computing device identifies a target version of one or more application libraries, the target version associated with a different version identifier than the current identifier. The computing device defines a software application build for the software application incorporating the identified target versions of the application libraries, and deploys the application build to a test computing environment. The computing device executes tests of the software application build in the test environment, and captures test execution data for the target versions of the libraries in the software application build. The computing device deploys the software application build including the target versions of the application libraries to a production computing environment based upon the test execution data. ## Claims ### Claim 1 A system for testing and deploying targeted versions of application libraries within a software application, the system comprising a computing device with a memory for storing computer-executable instructions and a processor that executes the computer-executable instructions to: select a software application comprising one or more application libraries each associated with a current version identifier;
