From 2ecd1296b6ba9ca8b07b3fbf4a11b7f3ec91038e Mon Sep 17 00:00:00 2001 From: diogo464 Date: Thu, 26 Jun 2025 16:21:49 +0100 Subject: Add comprehensive root directory validation tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These tests cover edge cases including: - Root directory specified as file instead of directory - Non-existent root directories - .demon directory exists as file in git root - Permission denied scenarios - Symlink handling (valid and broken) - Invalid UTF-8 paths - Deeply nested paths Most validation is already working correctly, but these tests document and verify the expected behavior for edge cases. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- tests/root_validation.rs | 337 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 337 insertions(+) create mode 100644 tests/root_validation.rs (limited to 'tests/root_validation.rs') diff --git a/tests/root_validation.rs b/tests/root_validation.rs new file mode 100644 index 0000000..61263f2 --- /dev/null +++ b/tests/root_validation.rs @@ -0,0 +1,337 @@ +use assert_cmd::Command; +use predicates::prelude::*; +use std::fs; +use std::path::PathBuf; +use std::time::Duration; +use tempfile::TempDir; + +// Root directory validation edge case tests + +#[test] +fn test_root_dir_is_file_not_directory() { + let temp_dir = TempDir::new().unwrap(); + + // Create a file instead of a directory + let file_path = temp_dir.path().join("not_a_directory"); + fs::write(&file_path, "this is a file").unwrap(); + + // Try to use the file as root directory - should fail + let mut cmd = Command::cargo_bin("demon").unwrap(); + cmd.args(&[ + "run", + "--root-dir", + file_path.to_str().unwrap(), + "test", + "echo", + "hello", + ]) + .assert() + .failure() + .stderr(predicate::str::contains("not a directory")); +} + +#[test] +fn test_root_dir_does_not_exist() { + let temp_dir = TempDir::new().unwrap(); + + // Use a non-existent path + let nonexistent_path = temp_dir.path().join("does_not_exist"); + + // Try to use non-existent path as root directory - should fail + let mut cmd = Command::cargo_bin("demon").unwrap(); + cmd.args(&[ + "run", + "--root-dir", + nonexistent_path.to_str().unwrap(), + "test", + "echo", + "hello", + ]) + .assert() + .failure() + .stderr(predicate::str::contains("does not exist")); +} + +#[test] +fn test_git_root_demon_dir_exists_as_file() { + // Create a temporary git repo + let temp_dir = TempDir::new().unwrap(); + let git_dir = temp_dir.path().join(".git"); + std::fs::create_dir(&git_dir).unwrap(); + + // Create .demon as a FILE instead of directory + let demon_file = temp_dir.path().join(".demon"); + fs::write(&demon_file, "this should be a directory").unwrap(); + + // Change to the temp directory + let original_dir = std::env::current_dir().unwrap(); + std::env::set_current_dir(temp_dir.path()).unwrap(); + + // Restore directory when done + struct DirGuard(PathBuf); + impl Drop for DirGuard { + fn drop(&mut self) { + let _ = std::env::set_current_dir(&self.0); + } + } + let _guard = DirGuard(original_dir); + + // Run command without --root-dir (should use git root and fail) + let mut cmd = Command::cargo_bin("demon").unwrap(); + cmd.args(&["run", "test", "echo", "hello"]) + .assert() + .failure() + .stderr(predicate::str::contains("exists but is not a directory")); +} + +#[test] +fn test_git_root_demon_dir_permission_denied() { + // This test is tricky to implement portably since it requires creating + // a directory with restricted permissions.
