Test Double
===========

[](#test-double)

A modern PHP test double library that puts developer experience first.

- **Zero learning curve** — create a `TestDouble` and start testing immediately. No taxonomy to memorize, no upfront decisions about mocks vs. spies vs. partials.
- **Failures for humans** — no terse output, no internal class identifiers to decode, just a plain-English next step.
- **One clean API** — a handful of methods, no aliases, no hidden nuance. If you can guess the method name, you're probably right.
- **Ready for contribution** — small, well-bounded internals mean no reverse-engineering the whole library for your first PR.

Installation
------------

[](#installation)

```
composer require --dev jasonmccreary/test-double
```

Usage
-----

[](#usage)

```
$repository = TestDouble::for(BookRepository::class);
$repository->expects('find')->with(123)->returns($book);

$service = new CatalogService($repository);
$service->lookup(123);

$repository->received('recordView')->with($book);
```

Documentation
-------------

[](#documentation)

Full docs — creating doubles, modes (Loose/Strict/Passthru), argument matching, verification, failure messages, PHPUnit integration, and contributing — live at [testdoublephp.com](https://testdoublephp.com/).

Contributing
------------

[](#contributing)

Contributions should target the `master` branch, follow the project's code style, and include tests. See [Contributing](https://testdoublephp.com/contributing) for the project's standing policies (no aliases, module boundaries, frozen public API) and walkthroughs for adding a matcher or improving a failure message.
