Dataset and evaluation for the paper "ERRATUM: Repairing Broken Locators in Web Test Scripts using Tree Matching". Two datasets were used: - The wayback dataset (wayback_dataset.json) - The mutation dataset (mutation_dataset.json) Each one was used to evaluate both state-of-the-art locator repair solution WATER and our novel tree matching-based approach. The results of this evaluation presented in our paper are in the following files: - eval_mutation.json - eval_wayback.json
