Prompt:
### Instruction:
Improve the test suite below. Add more test methods to cover missing cases.
Only output Python code, no explanation.

### Suggestions:
# - test that adjac((0, 0)) returns [[-1, -1], [-1, 0], [-1, 1], [0, -1], [0, 0], [0, 1], [1, -1], [1, 0], [1, 1]]
# - test that adjac((5, 5)) returns [[4, 4], [4, 5], [4, 6], [5, 4], [5, 5], [5, 6], [6, 4], [6, 5], [6, 6]]
# - test that adjac(0) raises TypeError when input is not a tuple

### Function:
def adjac(ele, sub = []):
  if not ele:
     yield sub
  else:
     yield from [idx for j in range(ele[0] - 1, ele[0] + 2)
                for idx in adjac(ele[1:], sub + [j])]
def get_coordinates(test_tup):
  res = list(adjac(test_tup))
  return (res)

### Current tests:
import unittest
from target import adjac

class TestAdjac(unittest.TestCase):
    def test_basic(self):
        assert get_coordinates((3, 4)) == [[2, 3], [2, 4], [2, 5], [3, 3], [3, 4], [3, 5], [4, 3], [4, 4], [4, 5]]

### Improved tests:


Write a function to find the second smallest number in a list.

import unittest
from target import second_smallest

class TestSecondSmallest(unittest.TestCase):
    def test_basic(self):
        self.assertEqual(second_smallest([1, 2, -8, -2, 0, -2]), -2)

        self.assertEqual(second_smallest([1, 2, 3]), 2)

    def test_all_equal(self):
        self.assertIsNone(second_smallest([5, 5, 5]))

    def test_empty_list(self):
        self.assertIsNone(second_smallest([]))

    def test_two_equal_elements(self):

    def test_large_list(self):
        self.assertEqual(second_smallest([10, 20, 30, 40, 50]), 20)

    def test_negative_numbers(self):
        self.assertEqual(second_smallest([-5, -10, -15]), -10)

    def test_list_with_duplicates(self):
        self.assertEqual(second_smallest([1, 2, 2, 3, 3, 3]), 2)

    def test_list_with_negative_and_positive(self):
        self.assertEqual(second_smallest([-5, 0, 5]), 0)
