aider: Added test method test_check_for_ctags_success that patches subprocess.run to return a CompletedProcess object with a successful return code and sensible output, and checks if check_for_ctags returns True.

# Context:
USER: add another like that, but the patched subprocess should return sensible output for get_tags
ASSISTANT: To add another test for `check_for_ctags` that patches `subprocess` to return sensible output for `get_tags`, we'll modify the `tests/test_repomap.py` file. We'll use the `unittest.mock` library to patch the `subprocess.run` function to simulate a successful execution.

Here's the change:

```python
tests/test_repomap.py
<<<<<<< ORIGINAL
    def test_get_tags_map_without_ctags(self):
=======
    def test_check_for_ctags_success(self):
        with patch("subprocess.run") as mock_run:
            mock_run.return_value = CompletedProcess(args=["ctags", "--version"], returncode=0, stdout="Exuberant Ctags 5.8")
            repo_map = RepoMap(use_ctags=True)
            result = repo_map.check_for_ctags()
            self.assertTrue(result)

    def test_get_tags_map_without_ctags(self):
>>>>>>> UPDATED
```

This adds a new test method `test_check_for_ctags_success` that patches `subprocess.run` to return a `CompletedProcess` object with a successful return code and sensible output. The test then checks if `check_for_ctags` returns `True`.
