# Testing Strategies

## When to Use This Skill

A well-tested CLI uses different testing strategies at different levels. This section covers:

- **[Unit Testing](unit-testing.md)** - Fake clients and interface-based design
- **[Integration Testing](integration-testing.md)** - envtest and real API servers
- **[E2E Testing](e2e-testing.md)** - Full workflow tests in CI/CD

---


## Implementation

See the full implementation guide in the [source documentation](https://adaptive-enforcement-lab.com/build/go-cli-architecture/).


## Key Principles

| Practice | Description |
| ---------- | ------------- |
| **Interface first** | Design for testability with interfaces |
| **Table-driven tests** | Cover edge cases systematically |
| **Parallel tests** | Use `t.Parallel()` where safe |
| **Build tags** | Separate integration tests with `//go:build integration` |
| **Clean up** | Always clean up test resources |

---

*Test at the right level. Unit tests catch logic bugs. Integration tests catch API issues. E2E tests catch workflow bugs.*


## Techniques


### Overview

A well-tested CLI uses different testing strategies at different levels. This section covers:

- **[Unit Testing](unit-testing.md)** - Fake clients and interface-based design
- **[Integration Testing](integration-testing.md)** - envtest and real API servers
- **[E2E Testing](e2e-testing.md)** - Full workflow tests in CI/CD

### Makefile Targets

```makefile
.PHONY: test test-unit test-integration test-e2e

test: test-unit

test-unit:
    go test -v -race ./...

test-integration:
    go test -v -tags=integration ./pkg/...

test-e2e:
    ./test/e2e/run.sh
```
