# Aider chat conversation:
USER: in `test_check_gitignore` can we have gitpython not use the global gitignore?
ASSISTANT: To ensure that GitPython does not use the global gitignore, we can set the `GIT_CONFIG_GLOBAL` environment variable to point to a non-existent file or an empty temporary file during the test execution. This will effectively ignore the global gitignore settings.
We will modify the `test_check_gitignore` method in the `tests/test_main.py` file to set the `GIT_CONFIG_GLOBAL` environment variable before the test runs and reset it after the test is completed.
Here are the *SEARCH/REPLACE* blocks:
tests/test_main.py
```python
<<<<<<< SEARCH
def test_check_gitignore(self):
make_repo()
io = InputOutput(pretty=False, yes=True)
cwd = Path.cwd()
gitignore = cwd / ".gitignore"
self.assertFalse(gitignore.exists())
check_gitignore(cwd, io)
self.assertTrue(gitignore.exists())
self.assertEqual(".aider*", gitignore.read_text().splitlines()[0])
gitignore.write_text("one\ntwo\n")
check_gitignore(cwd, io)
self.assertEqual("one\ntwo\n.aider*\n", gitignore.read_text())
=======
def test_check_gitignore(self):
with tempfile.NamedTemporaryFile() as temp_gitconfig:
os.environ['GIT_CONFIG_GLOBAL'] = temp_gitconfig.name
make_repo()
io = InputOutput(pretty=False, yes=True)
cwd = Path.cwd()
gitignore = cwd / ".gitignore"
self.assertFalse(gitignore.exists())
check_gitignore(cwd, io)
self.assertTrue(gitignore.exists())
self.assertEqual(".aider*", gitignore.read_text().splitlines()[0])
gitignore.write_text("one\ntwo\n")
check_gitignore(cwd, io)
self.assertEqual("one\ntwo\n.aider*\n", gitignore.read_text())
del os.environ['GIT_CONFIG_GLOBAL']
>>>>>>> REPLACE
```
This change will create a temporary file to act as a dummy global git configuration file and set the `GIT_CONFIG_GLOBAL` environment variable to its path. After the test, it will delete the environment variable to avoid affecting other tests or operations.
