# Context:
USER: add a test for `replace_part_with_missing_leading_whitespace`
ASSISTANT: To add a test for `replace_part_with_missing_leading_whitespace`, we will modify the `tests/test_utils.py` file.
```python
tests/test_utils.py
<<<<<<< ORIGINAL
if __name__ == "__main__":
unittest.main()
=======
def test_replace_part_with_missing_leading_whitespace(self):
whole = " line1\n line2\n line3\n"
part = "line1\nline2"
replace = "new_line1\nnew_line2"
expected_output = " new_line1\n new_line2\n line3\n"
result = utils.replace_part_with_missing_leading_whitespace(whole, part, replace)
self.assertEqual(result, expected_output)
if __name__ == "__main__":
unittest.main()
>>>>>>> UPDATED
```
This new test case checks if the `replace_part_with_missing_leading_whitespace` function correctly handles the case when the part and replace blocks have missing leading whitespaces.
# Context:
USER: the final test SHOULD raise ValueError
ASSISTANT: I understand that you want the final test in `tests/test_utils.py` to raise a `ValueError`. I will modify the test to check for the exception.
```python
tests/test_utils.py
<<<<<<< ORIGINAL
# Should raise a ValueError!
list(utils.find_original_update_blocks(edit))
=======
with self.assertRaises(ValueError):
list(utils.find_original_update_blocks(edit))
>>>>>>> UPDATED
```
Now, the final test in `tests/test_utils.py` will check if a `ValueError` is raised.
# Context:
USER: in test_find_original_update_blocks_unclosed, assert that it throws a valueerror containing the word "Incomplete"
ASSISTANT: To add the test for ValueError containing the word "Incomplete" in the `test_find_original_update_blocks_unclosed` function, you can use the `assertRaises` context manager and check if the exception message contains the word "Incomplete". Here's the change:
```python
tests/test_utils.py
<<<<<<< ORIGINAL
utils.find_original_update_blocks(edit)
=======
with self.assertRaises(ValueError) as cm:
utils.find_original_update_blocks(edit)
self.assertIn("Incomplete", str(cm.exception))
>>>>>>> UPDATED
```
