Introduction
------------

[](#introduction)

This project provides sniffs for some design patterns that improve unit test code testability:

- Use dependency injection (do not create instances using **new**)
- Limit the length for a call chain ($this->property->service->method->troubles)
- Do not call methods of the same class (this is a sign that your code is too complicated and you should split it in different services)
- Not use static calls (Service::method())
- Use only public methods (private methods cannot be really unit tested, and they indicate that you should be thinking about creating a new service)

It also provides two other sniffs, useful for CI environments:

- Check that a test case exists for every class
- Check that there is at least one test for every method

How to use
----------

[](#how-to-use)

1. Install [PHPCodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
2. Install phpcs-testability using Composer

```
composer require --dev elijahb/phpcs-testability

```

3. Add the standard to your custom PHPCodeSniffer ruleset.xml file

```

```

Recommendations
---------------

[](#recommendations)

You could also use another two sniffs to complement the ones in this projects:

- Generic.Metrics.NestingLevel (with a nesting level of 2)
- Generic.Metrics.CyclomaticComplexity (with a complexity level of 3)

Using all this sniffs, ideally inside a CI environment, you will be assured to have maintainable and fully unit tested code.
