Testing Slick Prompt

Quick Start

# Run all tests
just test

# Or run directly
./test.sh

Test Coverage

Integration Tests (19 tests)

Basic Functionality:

1. Basic git repository detection
2. Non-git directory handling
3. Modified files detection
4. Staged files detection
5. Untracked files detection
6. Multiple file states
7. JSON output format validation

Edge Cases: 8. Detached HEAD state 9. Prompt display integration 10. Empty repository handling

Performance: 11. Performance (fetch disabled) 16. Fetch disabled with unreachable remote 17. Performance benchmark (10 iterations)

Network & Auth Protection: ⚡ 11. HTTPS remote handling 12. SSH remote timeout (unreachable IP) 13. SSH auth prompt protection (prevents password/key prompts) 🔒 14. Git user name detection

Cargo Test Suite (98 tests)

cargo test

• 35 prompt/lib/context tests (src/lib.rs, src/context.rs, and src/prompt.rs)
• 12 auth cache tests
• 9 environment tests
• 8 git integration tests
• 5 git unit tests
• 6 elapsed-time prompt tests
• 23 prompt rendering tests

Total: 117 checks (98 cargo tests + 19 integration tests)

Auth/Credential Protection

Test #13 verifies that slick never prompts for credentials:

# What it tests:
git remote add origin git@github.com:fake-org/private-repo.git
slick precmd  # Should NOT prompt for password/SSH key

# Protection mechanisms tested:
- GIT_TERMINAL_PROMPT=0
- GIT_ASKPASS=echo
- SSH_ASKPASS=echo  
- SSH BatchMode=yes
- Timeout protection

Result: ✅ No hanging, no password prompts, completes quickly

Manual Testing

Test Auth Lock Detection

The auth lock symbol (🔒) appears when SSH authentication is required:

# Create repo with SSH remote that requires auth
mkdir /tmp/test-auth-lock && cd /tmp/test-auth-lock
git init
git config user.email "test@test.com"
git config user.name "Test User"
echo "test" > file.txt
git add . && git commit -m "init"
git checkout -b main

# Add private repo remote (one that requires SSH key)
git remote add origin git@github.com:private-org/private-repo.git
git config branch.main.remote origin
git config branch.main.merge refs/heads/main

# First time: no lock (auth check runs in background)
slick precmd
# Output: {"auth_failed":false,...}

# Wait a few seconds for background check
sleep 4

# Second time: lock appears! 🔒
slick precmd
# Output: {"auth_failed":true,...}

# View full prompt with lock symbol
DATA=$(slick precmd)
slick prompt -d "$DATA" -r 0
# Shows: ... main 🔒 ...

How it works:

1. First cd into repo: auth check runs asynchronously in background
2. Background check tests SSH connection with ssh -o BatchMode=yes
3. Result cached in ~/.cache/slick/auth_* for 5 minutes
4. Next prompt: reads cache and displays lock if auth is required

Cache location:

ls -la ~/.cache/slick/
cat ~/.cache/slick/auth_*  # timestamp:status (1=auth required)

Test Timeout Protection

# Add unreachable remote
git remote add origin git@192.0.2.1:fake/repo.git

# Should complete in < 6 seconds
time slick precmd

What Gets Tested

Scenario	Test #	What It Verifies
SSH unreachable	12	Timeout works (no hang)
SSH auth required	13	No password prompt, no hang
HTTPS remote	11	Quick completion
No remote	1-10	Normal git operations
Fetch disabled	16	Skips network entirely

CI/CD

Performance Expectations

Test	Expected Time
Local operations (fetch disabled)	< 100ms
HTTPS remote	< 3s
SSH unreachable	< 6s
SSH auth required	< 8s
Benchmark average	< 100ms
