# backup-suite Implementation Guide
**Purpose**: Add `BACKUP_SUITE_YES` environment variable support for CI/CD compatibility
**Effort**: ~10 minutes
**Files to modify**: 1 file (`src/main.rs` or `src/ui.rs`)
---
## Implementation
### Step 1: Add helper function
Add this function to `src/main.rs` or a new `src/ui.rs`:
```rust
/// Check if auto-confirmation is enabled via environment variable
///
/// This allows running backup-suite in CI/CD environments without TTY.
///
/// # Environment Variables
/// - `BACKUP_SUITE_YES`: Set to "true" or "1" to auto-confirm all prompts
/// - `CI`: Detected automatically (GitHub Actions, GitLab CI, etc.)
///
/// # Examples
/// ```bash
/// # CI environment
/// BACKUP_SUITE_YES=true backup-suite remove target1
///
/// # Or use CI detection
/// CI=true backup-suite cleanup
/// ```
fn should_auto_confirm() -> bool {
// Check BACKUP_SUITE_YES environment variable
if let Ok(val) = std::env::var("BACKUP_SUITE_YES") {
return val == "true" || val == "1" || val.to_lowercase() == "yes";
}
// Check CI environment variable (common in CI/CD systems)
if let Ok(val) = std::env::var("CI") {
return val == "true" || val == "1";
}
false
}
```
### Step 2: Update confirmation prompts
**Before** (interactive only):
```rust
use dialoguer::Confirm;
fn confirm_remove(target: &str) -> Result<bool> {
let confirmed = Confirm::new()
.with_prompt(format!("本当に {} を削除しますか？", target))
.interact()?;
Ok(confirmed)
}
```
**After** (CI-compatible):
```rust
use dialoguer::Confirm;
fn confirm_remove(target: &str) -> Result<bool> {
// Auto-confirm in CI environment
if should_auto_confirm() {
eprintln!("本当に {} を削除しますか？ (auto-confirmed in CI)", target);
return Ok(true);
}
// Interactive prompt in normal environment
let confirmed = Confirm::new()
.with_prompt(format!("本当に {} を削除しますか？", target))
.interact()?;
Ok(confirmed)
}
```
### Step 3: Update all confirmation points
Apply the pattern to all interactive confirmations:
1. **Remove command** (`src/commands/remove.rs`):
```rust
fn execute_remove(target: &str) -> Result<()> {
if should_auto_confirm() {
eprintln!("Removing {} (auto-confirmed)", target);
} else {
if !confirm_remove(target)? {
return Err(Error::Cancelled);
}
}
}
```
2. **Cleanup command** (`src/commands/cleanup.rs`):
```rust
fn execute_cleanup() -> Result<()> {
if should_auto_confirm() {
eprintln!("Cleanup all backups (auto-confirmed)");
} else {
if !confirm_cleanup()? {
return Err(Error::Cancelled);
}
}
}
```

## Testing
### Manual Test
```bash
# Test 1: Auto-confirm with BACKUP_SUITE_YES
BACKUP_SUITE_YES=true cargo run -- remove test-target
# Expected: No prompt, operation proceeds
# Test 2: Auto-confirm with CI variable
CI=true cargo run -- cleanup
# Expected: No prompt, operation proceeds
# Test 3: Normal interactive mode
cargo run -- remove test-target
# Expected: Interactive prompt appears
```
### Integration Test
```bash
# Run cli-testing-specialist tests
cd /path/to/backup-suite
cp /path/to/cli-testing-specialist/examples/backup-suite.cli-test-config.yml .cli-test-config.yml
# Generate and run tests
cli-testing-specialist analyze ./target/debug/backup-suite -o analysis.json
cli-testing-specialist generate analysis.json -o tests -c all
cli-testing-specialist run tests -f all -o reports
# Expected: 19/19 tests passing (100%)
```

## Error Handling
### Cancelled Operation
Update error type to handle cancellation:
```rust
// src/error.rs
#[derive(Debug, thiserror::Error)]
pub enum Error {
#[error("Operation cancelled by user")]
Cancelled,
// ... other errors
}
// Exit code for cancelled operations
impl Error {
pub fn exit_code(&self) -> i32 {
match self {
Error::Cancelled => 2, // Matches .cli-test-config.yml
_ => 1,
}
}
}
// src/main.rs
fn main() {
if let Err(e) = run() {
eprintln!("Error: {}", e);
std::process::exit(e.exit_code());
}
}
```
---
## Configuration File Location
Place `.cli-test-config.yml` in backup-suite project root:
```
backup-suite/
├── .cli-test-config.yml ← Here
├── Cargo.toml
├── src/
│ ├── main.rs
│ ├── commands/
│ │ ├── remove.rs
│ │ └── cleanup.rs
│ └── ...
└── tests/
```

## CI/CD Integration
### GitHub Actions
```yaml
# .github/workflows/test.yml
name: Test
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Run backup-suite tests
run: |
cargo build --release
cli-testing-specialist analyze ./target/release/backup-suite -o analysis.json
cli-testing-specialist run tests -f all
env:
BACKUP_SUITE_YES: "true" # Auto-confirm in CI
```
### GitLab CI
```yaml
# .gitlab-ci.yml
test:
script:
- cargo build --release
- cli-testing-specialist analyze ./target/release/backup-suite
- cli-testing-specialist run tests -f all
variables:
BACKUP_SUITE_YES: "true"
```
---
## Troubleshooting
### Issue: Tests still fail with "not a terminal"
**Solution**: Ensure `should_auto_confirm()` is called BEFORE `dialoguer::Confirm`:
```rust
// WRONG: dialoguer called first
let confirmed = Confirm::new().interact()?; // Error in CI
// CORRECT: Check environment first
if should_auto_confirm() {
return Ok(true);
}
let confirmed = Confirm::new().interact()?;
```
### Issue: Exit code is 1 instead of 2 for cancellation
**Solution**: Update error handling to return exit code 2:
```rust
impl Error {
pub fn exit_code(&self) -> i32 {
match self {
Error::Cancelled => 2, // Must match .cli-test-config.yml
_ => 1,
}
}
}
```
