🧪 Add testing foundation for main.py#3
Conversation
The code/main.py was an empty starter file. To enable testing, a basic CLI entrypoint using argparse was added. The tests/test_main.py checks for correct argument parsing and default values. Co-authored-by: NITISH-R-G <225521762+NITISH-R-G@users.noreply.github.com>

Reviewer's GuideAdds an argparse-based CLI entry point in main.py and establishes a corresponding pytest suite that exercises default/custom arguments, the --sample flag, help output, and invalid-argument handling for both parse_args and main().

Hey - I've found 2 issues, and left some high level feedback:
- The imported
Pathfrompathlibinmain.pyis unused and can be removed to keep the module minimal. - The tests assert against exact argparse error/help messages (e.g.,
"unrecognized arguments: --invalid-flag"), which can be brittle; consider asserting on key substrings or patterns that are less likely to change across Python versions.

## Overall Comments
- The imported `Path` from `pathlib` in `main.py` is unused and can be removed to keep the module minimal.
- The tests assert against exact argparse error/help messages (e.g., `"unrecognized arguments: --invalid-flag"`), which can be brittle; consider asserting on key substrings or patterns that are less likely to change across Python versions.

**suggestion (testing):** Also assert that the help text is printed in `test_main_help_returns_zero` to fully validate `--help` behavior.
Since `parse_args(["--help"])` prints the help text before exiting, please capture stdout/stderr and assert a key phrase from the help, e.g.:
```python
def test_main_help_returns_zero(capsys):
exit_code = main(["--help"])
assert exit_code == 0
captured = capsys.readouterr()
assert "Multi-Modal Evidence Review System" in captured.out
```
This verifies the help content from the main entry point, not just the exit code.
```suggestion
def test_main_help_returns_zero(capsys):
exit_code = main(["--help"])
assert exit_code == 0
captured = capsys.readouterr()

**suggestion (testing):** Consider asserting that the final success message is printed to ensure the whole happy-path is exercised.
Since `main` prints a final status line, it’d be good to assert on it here as well to fully cover the happy path and catch regressions that skip or change the message:
```python
assert "Pipeline completed successfully." in captured.out
```

Remove unnecessary f-string prefix on static text.
This triggers Ruff F541 and can fail lint checks; use a normal string literal.
Proposed fix
- print(f"Starting evidence review pipeline...")
+ print("Starting evidence review pipeline...")📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Drop unused capsys fixture parameters in two tests.
These trigger Ruff ARG001; removing them keeps the suite lint-clean.

🎯 What: The testing gap addressed:
code/main.pywas an empty starter file without tests. Added a basicargparsebased entry point tomain.pyand a corresponding test suite intests/test_main.py.📊 Coverage: What scenarios are now tested: CLI default arguments, custom input/output arguments,
--sampleflag toggles,--helpfunctionality, and handling of invalid arguments.✨ Result: The improvement in test coverage: A solid testing foundation is established for the main entry point of the pipeline before adding core logic. All test scenarios pass successfully.
