Merge #54: Fix destroy command: accept working_dir parameter

josecelano · josecelano · commit 2c5f8a52a641 · 2025-10-27T18:36:30.000Z
1da2edc fix: update doctest example to include working_dir parameter (copilot-swe-agent[bot]) a08fae4 fix: update destroy tests to match actual behavior (copilot-swe-agent[bot]) 36c8518 fix: add working_dir parameter to destroy command (copilot-swe-agent[bot]) 3dab583 Initial plan (copilot-swe-agent[bot]) Pull request description: ## Summary Fixed the critical bug where destroy command didn't accept or use the `--working-dir` parameter, preventing it from destroying environments created with custom working directories. ## Changes Made - [x] Updated `destroy::handle()` signature to accept `working_dir: &Path` parameter - [x] Updated command dispatcher to pass `working_dir` to destroy handler - [x] Added `ProcessRunner::run_destroy_command()` test helper method - [x] Created comprehensive E2E tests for destroy with working directories - [x] Fixed doctest examples to use new function signature - [x] All linters pass (markdown, yaml, toml, cspell, clippy, rustfmt, shellcheck) - [x] All 974 unit tests pass - [x] All 8 E2E tests pass (4 create + 4 destroy) - [x] All 4 doctests pass ## Technical Details The destroy command was hardcoded to use `PathBuf::from("data")` as the repository base directory, while the create command properly used the `--working-dir` parameter. This caused a mismatch where: - Create saved environments at: `{working_dir}/{env_name}/environment.json` - Destroy looked for them at: `data/{env_name}/environment.json` The fix passes `working_dir` from CLI through to the repository factory in the destroy handler, matching the create command's pattern. ## Testing **E2E Tests verify:** 1. ✅ Destroy with default working directory (backward compatibility) 2. ✅ Destroy with custom working directory 3. ✅ Full lifecycle: create → destroy with custom working directory 4. ✅ Error handling when environment not found **Doctests verify:** 1. ✅ destroy::handle() example with working_dir parameter 2. ✅ DestroyError::help() example with working_dir parameter **Note:** Environment state files are preserved in "Destroyed" state for idempotency and audit trail purposes, rather than being completely deleted.  <details> <summary>Original prompt</summary> ---- *This section details on the original issue you should resolve* <issue_title>[Subissue 9/10] Fix Destroy Command: Add Working Directory Support</issue_title> <issue_description># Fix Destroy Command: Accept Working Directory Parameter **Epic Subissue**: 9 of 9 **Issue**: #Y (to be assigned) **Parent Epic**: [#34](#34) - Create Environment Command **Depends On**: Subissue 8 - Fix Destroy Command Created State Handling **Related**: [Destroy Presentation Layer](../../src/presentation/commands/destroy.rs), [Command Dispatcher](../../src/presentation/commands/mod.rs) ## Overview Fix a critical bug in the destroy command where it doesn't accept or use the `--working-dir` parameter, causing it to fail when environments are created with custom working directories. The destroy command is hardcoded to look for environments in the `data/` directory, ignoring the `--working-dir` CLI argument that the create command properly supports. This bug prevents users from managing environment lifecycles when working with custom workspace locations, a feature explicitly supported by the `--working-dir` flag in the CLI. **Dependencies**: This issue depends on Subissue 8 (Created State Handling) being completed first, as manual testing requires being able to destroy Created state environments successfully. ## Goals - [ ] Fix destroy command to accept `working_dir` parameter - [ ] Pass `working_dir` through the command execution chain - [ ] Maintain backward compatibility with default behavior - [ ] Add comprehensive tests for both default and custom working directories ## 🏗️ Architecture Requirements **DDD Layer**: Presentation (CLI interface) **Module Path**: `src/presentation/commands/destroy.rs` + `src/presentation/commands/mod.rs` **Pattern**: CLI Command Pattern ### Module Structure Requirements - [ ] Follow DDD layer separation (see [docs/codebase-architecture.md](../../codebase-architecture.md)) - [ ] Presentation layer handles CLI argument passing to command handlers - [ ] Maintain consistency with create command's working directory handling ### Architectural Constraints - [ ] Working directory must flow from CLI through to repository factory - [ ] Error handling follows project conventions (see [docs/contributing/error-handling.md](../contributing/error-handling.md)) - [ ] Maintain backward compatibility with default working directory (`.`) ### Anti-Patterns to Avoid - ❌ Hardcoding directory paths in command handlers - ❌ Breaking changes to existing destroy behavior with default working directory - ❌ Inconsistency between create and destroy command working directory handling ## Specifications ### Current Behavior (Incorrect) The destroy command is hardcoded to look for environments in the `data/` directory: ```rust // src/presentation/commands/destroy.rs (line 74) pub fn handle(environment_name: &str) -> Result<(), DestroyError> { // ... // Create repository for loading environment state let repository_factory = RepositoryFactory::new(Duration::from_secs(30)); let repository = repository_factory.create(std::path::PathBuf::from("data")); // ❌ Hardcoded // ... } ``` The command dispatcher doesn't pass `working_dir` to the destroy handler: ```rust // src/presentation/commands/mod.rs pub fn execute(command: Commands, working_dir: &std::path::Path) -> Result<(), CommandError> { match command { Commands::Create { action } => { create::handle_create_command(action, working_dir)?; // ✅ Uses working_dir Ok(()) } Commands::Destroy { environment } => { destroy::handle(&environment)?; // ❌ Doesn't receive working_dir Ok(()) } } } ``` **Impact**: Environments created with custom `--working-dir` cannot be found by the destroy command: ```bash # Create environment in custom directory ./torrust-tracker-deployer --working-dir /tmp/workspace create environment --env-file config.json # Destroy fails - looks in ./data/ instead of /tmp/workspace/data/ ./torrust-tracker-deployer --working-dir /tmp/workspace destroy test-env # Error: Environment not found ``` ### Expected Behavior The destroy command should accept and use the `working_dir` parameter just like the create command: **Step 1**: Update `destroy::handle()` signature to accept `working_dir`: ```rust // src/presentation/commands/destroy.rs pub fn handle(environment_name: &str, working_dir: &std::path::Path) -> Result<(), DestroyError> { // Create user output with default stdout/stderr channels let mut output = UserOutput::new(VerbosityLevel::Normal); // Display initial progress (to stderr) output.progress(&format!("Destroying environment '{environment_name}'...")); // Validate environment name let env_name = EnvironmentName::new(environment_name.to_string()).map_err(|source| { let error = DestroyError::InvalidEnvironmentName { nam... </details> - Fixes #51  --- 💬 We'd love your input!

+//! End-to-End Black Box Tests for Destroy Command
+//!
+//! This test suite provides true black-box testing of the destroy command
+//! by running the production application as an external process. These tests
+//! verify that the destroy command correctly handles the working directory
+//! parameter, ensuring environments can be destroyed from custom locations.
+//!
+//! ## Test Approach
+//!
+//! - **Black Box**: Runs production binary as external process
+//! - **Isolation**: Uses temporary directories for complete test isolation
+//! - **Coverage**: Tests complete workflow from environment creation to destruction
+//! - **Verification**: Validates environment is properly removed
+//!
+//! ## Test Scenarios
+//!
+//! 1. Default working directory: Destroy environment from current directory
+//! 2. Custom working directory: Destroy environment from temporary directory
+//! 3. Full lifecycle: Create → Destroy with custom working directory
