PHPUnit AssertArraySubset Extension
===================================

[](#phpunit-assertarraysubset-extension)

In PHPUnit 8 the function `assertArraySubset` was [deprecated](https://github.com/sebastianbergmann/phpunit/issues/3494). This function was often misunderstood and thus removed, but it still holds true as a very useful tool, hence it was extracted here.

**Disclaimer:**The initial version contained here is copied over from phpunit and is heavily based on the original work by [Márcio Almada](https://github.com/marcioAlmada).

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

[](#installation)

Simply use it by importing it with Composer

```
composer require --dev dms/phpunit-arraysubset-asserts

```

> 💡 The package can be safely required on PHP 5.4 to current in combination with PHPUnit 4.8.36/5.7.21 to current.
>
> When the PHPUnit `assertArraySubset()` method is natively available and not deprecated (PHPUnit 4.x - 7.x), the PHPUnit native functionality will be used. For PHPUnit 8 and higher, the extension will kick in and polyfill the functionality which was removed from PHPUnit.

Usage
-----

[](#usage)

You have two options to use this in your classes: either directly as a static call or as a trait if you wish to keep existing references working.
