Table 3.
Diffuseness of test smells in the dataset used for the external validation (480 test cases) and in the entire dataset (9,633 test cases). We reported the various combinations of test smells and non-test smells present in the datasets. The first row represents test cases that are no-smelly, the last row represents the test cases with all four test smells analyzed, and the rows in between are all combinations
