The test file path could have been recorded during the previous CI build when the knapsack_pro gem could not attribute the execution time of a test to a correct test file path. For instance, you have shared examples in your test suite, and the knapsack_pro gem could not correctly determine for which test file path they were executed. In such a case, the test file path should not be loaded because the actual test cases will be executed by loading a correct test file path. You can ignore this warning.")
