To install Brain Monkey you need:

• PHP 5.6+

• ​Composer​

Brain Monkey is available on Packagist, so the only thing you need to do is to add it as a dependency for your project.

That can be done by running following command in your project folder:

composer require brain/monkey:2.* --dev

As alternative you can directly edit your composer.json by adding:

{
  "require-dev": {
    "brain/monkey": "~2.0.0"
  }
}

I've used require-dev because, being a testing tool, Brain Monkey should not be included in production.

Brain Monkey can work with any testing framework, so it doesn't require any of them.

To run your tests you'll probably need to require a testing framework too, e.g. PHPUnit or phpspec.

Dependencies

Brain Monkey needs 2 libraries to work:

• ​Mockery (BSD-3-Clause)

• ​Patchwork (MIT)

They will be installed for you by Composer.

When installed in development mode (to test itself), Brain Monkey also requires:

• ​PHPUnit (MIT)
