.claude/skills/build-test-auto/# Automated Build & Test Workflow
## Overview
This skill provides automated build and test execution for various project types. It is triggered automatically when code changes are made or when tests need verification.
## Quick Reference
### Project Detection & Commands
```bash
# JavaScript/Node.js
if [ -f "package.json" ]; then
npm install && npm run build && npm test
fi
# Python
if [ -f "pyproject.toml" ] || [ -f "setup.py" ]; then
pip install -e . && python -m pytest
fi
# Rust
if [ -f "Cargo.toml" ]; then
cargo build && cargo test
fi
# Go
if [ -f "go.mod" ]; then
go build ./... && go test ./...
fi
# Java Maven
if [ -f "pom.xml" ]; then
mvn compile && mvn test
fi
# Java/Kotlin Gradle
if [ -f "build.gradle" ] || [ -f "build.gradle.kts" ]; then
./gradlew build && ./gradlew test
fi
# Ruby
if [ -f "Gemfile" ]; then
bundle install && bundle exec rspec
fi
# Make-based
if [ -f "Makefile" ]; then
make && make test
fi
```
## Workflow Steps
### 1. Pre-Build Checks
- Verify dependencies are installed
- Check for required tools (use `mise` if available)
- Validate configuration files
### 2. Build Phase
- Run the build command
- Capture all output
- Stop immediately on build failure
- Show exact error location
### 3. Test Phase
- Run the full test suite
- Capture test output with verbose mode
- Document all failures
### 4. Failure Analysis
For each failure:
1. Identify the test name and file
2. Show the exact error message
3. Display relevant stack trace
4. Analyze root cause
### 5. Fix & Verify
- Apply minimal fixes
- Re-run tests to confirm
- Report final status
## Linting
After tests pass, also run linting:
| Project Type | Lint Command |
|-------------|--------------|
| Node.js | `npm run lint` |
| Python | `ruff check .` or `flake8` |
| Rust | `cargo clippy` |
| Go | `go vet ./...` |
## Tips
- Use `mise` to install missing runtimes
- Check `.nvmrc`, `.python-version`, `.tool-versions` for version requirements
- Run lin
