Scenario-Based Organization + +Organize by **what you're testing**, not by command: + +- **Smoke** (`smoke.rs`): One-liners that verify commands don't crash + - Focus: "Does it run?" + - Pattern: Individual tests per behavior + +- **Happy Path** (`happy_path.rs`): Full workflow validation + - Focus: "Does it work correctly?" + - Pattern: Single comprehensive test per workflow + +- **Edge Cases** (`edge_cases.rs`): Error handling and special scenarios + - Focus: "What happens when things go wrong?" + - Pattern: Individual tests per edge case + +### 2. Struct-Based Assertions + +**Prefer deserializing config files into structs over string matching:** + +```rust +// ✅ Good - Type-safe, refactoring-friendly +let config = ctx.load_trix_config(); +assert!(!config.wallets.is_empty()); +assert_eq!(config.protocol.version, "0.0.0"); + +// ❌ Bad - Brittle, breaks on format changes +let content = ctx.read_file("trix.toml"); +assert!(content.contains("version = \"0.0.0\"")); +``` + +### 3. Test Function Naming + +**Don't repeat scenario context in function names:** + +```rust +// ✅ Good - Context is the file (happy_path.rs) +fn init_creates_valid_project() { } +fn check_validates_valid_project() { } +fn devnet_starts_in_background() { } + +// ❌ Bad - Redundant with file location +fn happy_path_init_creates_valid_project() { } +``` + +### 4.

Choose the Right File + +- **Smoke**: Quick sanity check - does the command exit 0? +- **Happy Path**: Full validation of a feature - files created, content correct +- **Edge Cases**: Specific scenarios like missing files, invalid inputs, preservation + +### 2. Use TestContext + +Always create a fresh `TestContext` for isolation: + +```rust +#[test] +fn my_new_test() { + let ctx = TestContext::new(); + // ... test code +} +``` + +### 3. Chain Commands for Workflows + +```rust +// Happy path spanning multiple commands +ctx.run_trix(&["init", "--yes"]); +ctx.run_trix(&["check"]); +ctx.run_trix(&["build"]); +``` + +### 4. Assert with Structs + +```rust +// Load config and assert on struct fields +let config = ctx.load_trix_config(); +assert!(!config.wallets.is_empty()); +assert_eq!(config.protocol.version, "0.0.0"); +``` + +## Key Patterns + +### Parallel Safety +Each test gets its own `TempDir`, so tests run in parallel safely. Never use `std::env::set_current_dir()` - use `Command::current_dir()` instead. + +### Lib + Binary Pattern +The project is structured as both a library and binary: +- `src/lib.rs` exports all modules publicly +- Tests import structs: `use trix::config::RootConfig;` +- This enables type-safe config assertions + +### File Preservation Tests +When testing file preservation (e.g., existing `.gitignore`): +1. Write the existing content +2. Run the command +3. Assert both old and new content exist + +### Background Processes +For commands that spawn long-running processes: +1. Use `--background` flag if available +2. Wait for port to confirm process is up +3. Always cleanup in test (even if test fails) + +## Complete Example + +```rust +// tests/e2e/happy_path.rs +use super::*; + +#[test] +fn my_feature_works() { + let ctx = TestContext::new(); + + // Setup: Initialize project + let init_result = ctx.run_trix(&["init", "--yes"]); + assert_success(&init_result); + + // Action: Run my command + let result = ctx.run_trix(&["my-command"]); + + // Assert: Command succeeded + assert_success(&result); + assert_output_contains(&result, "expected output"); + + // Assert: Files created correctly + ctx.assert_file_exists("output.txt"); + + // Assert: Config valid + let config = ctx.load_trix_config(); + assert!(!config.some_field.is_empty()); +} +``` + +## References + +- `tests/e2e/mod.rs` - TestContext implementation +- `tests/e2e/smoke.rs` - Smoke test examples +- `tests/e2e/happy_path.rs` - Happy path examples +- `tests/e2e/edge_cases.rs` - Edge case examples diff --git a/src/cli.rs b/src/cli.rs new file mode 100644 index 0000000..d9b1c92 --- /dev/null +++ b/src/cli.rs @@ -0,0 +1,63 @@ +//!
