.select_test_files_that_can_be_run(adapter_class, test_file_entities_to_run) ⇒ Object

Args:

test_file_entities_to_run - it can be list of slow test files that you want to run

Return:

subset of test_file_entities_to_run that are present on disk and it is subset of tests matching pattern KNAPSACK_PRO_TEST_FILE_PATTERN
Thanks to that we can select only slow test files that are within list of test file pattern we want to run tests for
