Example fix for weak assertions: // After the add command, verify it was actually staged:
let output = Command::new(assert_cmd::cargo::cargo_bin!("libra"))
.current_dir(dir.path())
.arg("status")
.output()
.unwrap();
let stdout = String::from_utf8_lossy(&output.stdout);
assert!(stdout.contains("empty.txt"), "File should be staged");VerdictRequest Changes - The tests are well-structured but need stronger assertions to be truly effective. The critical issues with weak assertions must be addressed to ensure tests actually validate the intended behavior. |

Missing assertion for expected behavior: The test name suggests this should verify a warning on double init, but there's no assertion checking for warning output. The comment on line 23 says "behavior may vary by implementation", which makes the test unclear.
Recommendation: Either:
- Assert that a specific warning message is displayed in stdout/stderr, or
- Assert that the
.libradirectory remains valid after double init, or - Rename the test to clarify what behavior is actually being tested (e.g.,
test_double_init_idempotency)
Example assertion:
let output = Command::new(assert_cmd::cargo::cargo_bin!("libra"))
.current_dir(dir.path())
.arg("init")
.output()
.unwrap();
let stderr = String::from_utf8_lossy(&output.stderr);
assert!(stderr.contains("already initialized") || stderr.is_empty());

Code duplication: The helper functions init_libra_repo and setup_test_repo are duplicated across 3 test files (test_add_empty_file.rs, test_add_sub_directory_file.rs, test_status_after_add.rs).
Recommendation: Extract these common helpers into a shared test utilities module to follow DRY principles:
- Create
tests/common/mod.rsortests/test_helpers.rs - Move shared setup functions there
- Import in test files with
use common::*;
This will make maintenance easier and ensure consistent test setup.

Weak assertion: The test only checks that the add command succeeds, but doesn't verify that the empty file was actually added to the staging area.
Recommendation: Add verification similar to test_status_after_add.rs to confirm the file appears in status output:
let output = Command::new(assert_cmd::cargo::cargo_bin!("libra"))
.current_dir(dir.path())
.arg("status")
.output()
.unwrap();
let stdout = String::from_utf8_lossy(&output.stdout);

Same issue as test_add_empty_file: Only checks command success without verifying the file was actually staged. Consider adding status verification.

The test asserts .success() on the second libra init, but the implementation explicitly treats re-initialization as an error and returns InitError::Io with AlreadyExists (see src/command/init.rs around the is_reinit check at lines ~439–446). With current behavior the CLI exits non‑zero, so this test will fail unless the command semantics are changed. If the intent is to warn and still succeed, the production code must be updated; otherwise the test should assert failure (or the specific warning on stderr).
Useful? React with 👍 / 👎.

Good assertion: ✅ This test properly verifies the expected outcome (.libra directory exists). This is the level of verification the other tests should aim for.

Good assertion with detailed error message: ✅ This is a good example of proper test verification - it checks the actual behavior and provides a clear failure message. However, the test doesn't verify the file shows up as "staged" vs just appearing in output.
Minor improvement suggestion: Consider also checking that the file is marked as "new" or "staged" in the status output to be more specific about what state it's in.

Pull request overview
This PR adds 5 new integration test files intended to cover edge cases for the libra project, specifically: repository initialization in empty directories, double initialization idempotency, adding empty files, handling deep directory structures, and verifying status output after adding files.
Changes:
- Added 5 new integration test files using assert_cmd for CLI testing
- Added assert_cmd dependency (v2.1.2) to dev-dependencies
- Tests use external command execution pattern rather than internal API calls

The helper functions init_libra_repo and setup_test_repo are duplicated identically across three test files (test_status_after_add.rs, test_add_sub_directory_file.rs, and test_add_empty_file.rs). This violates DRY principles and increases maintenance burden. Consider either: (1) following the existing pattern in tests/command/ which uses a shared test module with reusable utilities (see tests/command/mod.rs), or (2) creating a common test utilities module that these tests can import from.

The PR description mentions testing "Handling file paths with spaces", but none of the added test files actually test this scenario. The test_status_after_add.rs test only covers a simple filename "test.txt" without any spaces. Either add a test that actually covers filenames with spaces, or update the PR description to accurately reflect what is being tested.

These tests use assert_cmd to invoke the libra CLI binary, which is a different approach from the existing integration tests in tests/command/. The existing tests (e.g., tests/command/add_test.rs, tests/command/status_test.rs) use internal API calls with tokio::test and serial attributes, importing from a shared test module. This inconsistency makes the test suite harder to maintain. Consider following the established pattern: use tokio::test, import test utilities from the command module (super::*), and call command execute functions directly rather than spawning external processes.

The comment states "behavior may vary by implementation" but the test only asserts success without verifying what actually happens. The test name includes "warning" but doesn't check for any warning output. Either verify that appropriate feedback is given (warning message or silent success), or update the test name and comment to reflect that it only tests idempotency (that double init doesn't fail).

The assertion only checks that the string "test.txt" appears somewhere in the status output, which is a weak test. It doesn't verify the status prefix (e.g., "A " for added files in porcelain format) or the format of the output. The existing status tests in tests/command/status_test.rs show more rigorous verification patterns, checking specific status codes and output format. Consider strengthening this assertion to verify the actual status format.

The test only asserts that the add command succeeds, but doesn't verify that the file was actually added to the index. Consider adding verification similar to the existing tests in tests/command/add_test.rs:35-37, which check that the file appears in changes_to_be_committed() after being added.

Description: I have added 5 new integration tests in tests/r2cn_submission_test.rs to cover various edge cases for the libra project.
Tests covered:
init idempotency (double init)
Adding a zero-byte empty file
Tracking files in deep directory structures
Handling file paths with spaces
Verifying status output accuracy
All tests passed successfully without warnings as shown below:
