aider: The test case has been modified to add files to the directory and ensure they are added correctly.

# Aider chat conversation:

USER: put some files in the test_dir, and the test shouldn't look for the exception. it should make sure the files were added

ASSISTANT: To modify the test case to add files to the directory and ensure they are added correctly, we need to modify the `tests/test_commands.py` file.

Here is the proposed change:

```python
tests/test_commands.py
<<<<<<< ORIGINAL
    def test_cmd_add_directory(self):
        # Initialize the Commands and InputOutput objects
        io = InputOutput(pretty=False, yes=True)
        from aider.coders import Coder

        coder = Coder.create(models.GPT35, None, io, openai_api_key="deadbeef")
        commands = Commands(io, coder)

        # Create a directory
        os.mkdir("test_dir")

        # Call the cmd_add method with a directory
        with self.assertRaises(IsADirectoryError):
            commands.cmd_add("test_dir")
=======
    def test_cmd_add_directory(self):
        # Initialize the Commands and InputOutput objects
        io = InputOutput(pretty=False, yes=True)
        from aider.coders import Coder

        coder = Coder.create(models.GPT35, None, io, openai_api_key="deadbeef")
        commands = Commands(io, coder)

        # Create a directory and add files to it
        os.mkdir("test_dir")
        with open("test_dir/test_file1.txt", "w") as f:
            f.write("Test file 1")
        with open("test_dir/test_file2.txt", "w") as f:
            f.write("Test file 2")

        # Call the cmd_add method with a directory
        commands.cmd_add("test_dir")

        # Check if the files have been added to the chat session
        self.assertIn(str(Path("test_dir/test_file1.txt").resolve()), coder.abs_fnames)
        self.assertIn(str(Path("test_dir/test_file2.txt").resolve()), coder.abs_fnames)
>>>>>>> UPDATED
```

This new test case `test_cmd_add_directory` creates a directory named `test_dir`, adds two files to it, and attempts to add the directory using the `cmd_add` method. We then check if the files in the directory have been added to the chat session.
