This function is used to determine the indices when slicing the list of selected tests when ``options.first``(:attr:`find_last_index`=False) and/or ``options.last``(:attr:`find_last_index`=True) are used. :attr:`selected_tests` can be a list that contains multiple consequent occurrences of tests as part of the same test module, e.g.: ``` selected_tests = ['autograd', 'cuda', **'torch.TestTorch.test_acos', 'torch.TestTorch.test_tan', 'torch.TestTorch.test_add'**, 'utils'] ``` If :attr:`test`='torch' and :attr:`find_last_index`=False, result should be **2**. If :attr:`test`='torch' and :attr:`find_last_index`=True, result should be **4**.
