## Features
- **Declarative** - Provides a declarative API for defining fully-typed, isolated test environments from a single specification, including automatic mock generation and dependency wiring based on constructor metadata.
- **Type-Safe Refactoring** - Binds mocks to concrete TypeScript implementations so that changes to constructors, injected dependencies, and method signatures are validated at compile time, enabling confident refactors with less failing tests.
- **Standardized Testing Across Teams** - Exposes a uniform testing surface across NestJS, InversifyJS, and other DI setups, enabling consistent test structure and patterns regardless of the underlying framework.
- **AI Ready** - Provides a concise and strict test API that minimizes context requirements for LLM-based coding agents, enabling higher-quality generated tests, clearer and more actionable error messages that guide automatic self-correction, and a higher likelihood of completing test authoring in a single pass.
## Examples
### Solitary Mode
**Solitary mode** tests a single unit in complete isolation - all dependencies are automatically mocked. Use this when
you want to test your unit's logic without any real dependencies.
[Learn more about Solitary Tests](https://suites.dev/docs/guides/solitary)
```typescript
import { TestBed, type Mocked } from '@suites/unit';
describe('User Service', () => {
let userService: UserService; // Class under test
let userApi: Mocked<UserApi>; // Mock instance
let database: Mocked<Database>; // Mock instance
beforeAll(async () => {
// Create the test environment with automatic mocking
const testBed = await TestBed.solitary(UserService).compile();
userService = testBed.unit;
// Retrieve the mock instances
