# Context:
USER: stdin not stdout
ASSISTANT: I apologize for the confusion. To redirect stdin instead of stdout, we need to use `contextlib.redirect_stdin` instead of `contextlib.redirect_stdout`. Here's the updated code change for tests/test_main.py:
```python
tests/test_main.py
<<<<<<< ORIGINAL
with open(os.devnull, 'w') as dev_null:
with redirect_stdout(dev_null):
=======
with open(os.devnull, 'r') as dev_null:
with redirect_stdin(dev_null):
>>>>>>> UPDATED
main()
```
This code change replaces `redirect_stdout` with `redirect_stdin` and opens os.devnull in read mode ('r') instead of write mode ('w').
# Context:
USER: add a test case for main which makes a new empty dir, makes it the cwd and invokes main() with /dev/null piped to stdin.
ASSISTANT: To add a test case for main, we need to import the necessary modules, create a temporary directory, change the current working directory, and invoke the main function with /dev/null piped to stdin. Here's the code change for tests/test_main.py:
```python
tests/test_main.py
<<<<<<< ORIGINAL
=======
import os
import sys
import tempfile
from contextlib import redirect_stdout
from unittest import TestCase
from aider.main import main
class TestMain(TestCase):
def test_main_with_dev_null(self):
with tempfile.TemporaryDirectory() as temp_dir:
os.chdir(temp_dir)
with open(os.devnull, 'w') as dev_null:
with redirect_stdout(dev_null):
main()
>>>>>>> UPDATED
```
This code change imports the necessary modules, creates a new test class `TestMain`, and adds a test method `test_main_with_dev_null`. The test method creates a temporary directory, changes the current working directory to the temporary directory, and invokes the `main` function with /dev/null piped to stdout.
