1. A system comprising: one or more processors and executable instructions accessible on a computer-readable medium that, when executed, configure the one or more processors to at least: generate requirements artifacts from one or more sources, to transform the requirements artifacts into a standardized format, and to establish the transformed requirements artifacts in tested software code, the requirements artifacts including a first version and a second version of a specific requirement artifact; standardize and distribute various types of common test data across multiple business disciplines as data artifacts; manage test executions across multiple environments based on using the requirements artifacts established in the tested software code and the provided data artifacts, the multiple environments being where the tested software code is installed; analyze data resulting from the test executions that use the first version and the second version of the specific requirement artifact, and to compare performances of the test executions across the multiple environments using the data resulting from a first test execution of the first version and a second test execution of the second version; and report the analyzed data.
