# Aider chat conversation:
ASSISTANT: I understand that you want to complete the TODO task in the `test_new_file_edit_one_commit` method in the `tests/test_coder.py` file. However, the task is not clear. The TODO comment says:
```python
### TODO: assert that the next line raises git.exc.GitCommandError
```
This suggests that the following line of code should raise a `git.exc.GitCommandError` exception:
```python
repo.iter_commits(repo.active_branch.name)
```
To complete this task, we need to add a test assertion that checks if this line of code raises the `git.exc.GitCommandError` exception. We can use the `assertRaises` method from the `unittest.TestCase` class to do this.
Here is the change that needs to be made:
<source>python
tests/test_coder.py
<<<<<<< HEAD
### TODO: assert that the next line raises git.exc.GitCommandError
repo.iter_commits(repo.active_branch.name)
=======
with self.assertRaises(git.exc.GitCommandError):
repo.iter_commits(repo.active_branch.name)
>>>>>>> updated
</source>
This change will add an assertion that checks if the `repo.iter_commits(repo.active_branch.name)` line of code raises a `git.exc.GitCommandError` exception. If the line of code does not raise this exception, the test will fail.
# Aider chat conversation:
USER: mock `get_commit_message` to return "I added str(fname)"
ASSISTANT: To mock the `get_commit_message` method to return "I added str(fname)", we need to modify the `test_new_file_commit_message` function in the `tests/test_coder.py` file.
Here is the change needed:
<source>python
tests/test_coder.py
<<<<<<< ORIGINAL
# Get the latest commit message
commit_message = repo.head.commit.message
# Check that the latest commit message contains the filename
self.assertIn(str(fname), commit_message)
=======
# Mock the get_commit_message method to return "I added str(fname)"
repo.get_commit_message = MagicMock(return_value=f"I added {str(fname)}")
# Get the latest commit message
commit_message = repo.get_commit_message()
# Check that the latest commit message is "I added str(fname)"
self.assertEqual(commit_message, f"I added {str(fname)}")
>>>>>>> UPDATED
