Chef InSpec is an open-source testing framework for infrastructure with a human- and machine-readable language for specifying compliance, security and policy requirements.

```ruby
# Disallow insecure protocols by testing

describe package('telnetd') do
  it { should_not be_installed }
end

describe inetd_conf do
  its("telnet") { should eq nil }
end
```

Chef InSpec makes it easy to run your tests wherever you need. More options are found in our [CLI docs](https://docs.chef.io/inspec/cli/).

```bash
# run test locally
inspec exec test.rb

# run test on remote host via SSH
inspec exec test.rb -t ssh://user@hostname -i /path/to/key

# run test on remote host using SSH agent private key authentication. Requires Chef InSpec 1.7.1
inspec exec test.rb -t ssh://user@hostname

# run test on remote windows host via WinRM
inspec exec test.rb -t winrm://Administrator@windowshost --password 'your-password'

# run test on remote windows host via WinRM as a domain user
inspec exec test.rb -t winrm://windowshost --user 'UserName@domain' --password 'your-password'

# run test on docker container
inspec exec test.rb -t docker://container_id
```

# Features

- Built-in Compliance: Compliance no longer occurs at the end of the release cycle
- Targeted Tests: Chef InSpec writes tests that specifically target compliance issues
- Metadata: Includes the metadata required by security and compliance pros
- Easy Testing: Includes a command-line interface to run tests quickly

## Installation

Chef InSpec requires Ruby ( >= 2.4 ).

Note: Versions of Chef InSpec 4.0 and later require accepting the EULA to use. Please visit the [license acceptance page](https://docs.chef.io/chef_license_accept.html) on the Chef docs site for more information.

### Install as package

The Chef InSpec package is available for MacOS, RedHat, Ubuntu and Windows. Download the latest package at [Chef InSpec Downloads](https://downloads.chef.io/inspec) or install Chef InSpec via script:

```
# RedHat, Ubuntu, and macOS
curl https://omnitruck.chef.io/install.sh | sudo bash -s -- -P inspec

# Windows
. { iwr -useb https://omnitruck.chef.io/install.ps1 } | iex; install -project inspec
```

### Install it via rubygems.org

When installing from source, gem dependencies may require ruby build tools to be installed.

For CentOS/RedHat/Fedora:

```bash
yum -y install ruby ruby-devel make gcc gcc-c++
```

For Ubuntu:

```bash
apt-get -y install ruby ruby-dev gcc g++ make
```

To install the `inspec` executable, which requires accepting the [Chef License](https://docs.chef.io/chef_license_accept.html), run:

```bash
gem install inspec-bin
```

You may also use `inspec` as a library, with no executable. This does not require accepting the license. To install the library as a gem, run:

```bash
gem install inspec
```


### Usage via Docker

Download the image and define a function for convenience:

For Linux:

```
docker pull chef/inspec
function inspec { docker run -it --rm -v $(pwd):/share chef/inspec "$@"; }
```

For Windows (PowerShell):

```
docker pull chef/inspec
function inspec { docker run -it --rm -v "$(pwd):/share" chef/inspec $args; }
```

If you call `inspec` from your shell, it automatically mounts the current directory into the Docker container. Therefore you can easily use local tests and key files. Note: Only files in the current directory and sub-directories are available within the container.

```
$ ls -1
vagrant
test.rb

$ inspec exec test.rb -t ssh://root@192.168.64.2:11022 -i vagrant
..

Finished in 0.04321 seconds (files took 0.54917 seconds to load)
2 examples, 0 failures
```


### Install it from source

Note that installing from OS packages from [the download page](https://downloads.chef.io) is the preferred method.

That requires [bundler](http://bundler.io/):

```bash
bundle install
bundle exec inspec help
```

To install it as a gem locally, run:

```bash
gem build inspec.gemspec
gem install inspec-*.gem
```

On Windows, you need to install [Ruby](http://rubyinstaller.org/downloads/) with [Ruby Development Kit](https://github.com/oneclick/rubyinstaller/wiki/Development-Kit) to build dependencies with its native extensions.

### Install via Chef Habitat

Currently, this method of installation only supports Linux. See the [Chef Habitat site](https://www.habitat.sh/) for more information.

Download the `hab` binary from the [Chef Habitat](https://www.habitat.sh/docs/get-habitat/) site.

```bash
hab pkg install chef/inspec --binlink

inspec
```

### Run Chef InSpec

You should now be able to run:

```bash
$ inspec --help
Commands:
  inspec archive PATH                # archive a profile to tar.gz (default) ...
  inspec check PATH                  # verify all tests at the specified PATH
  inspec compliance SUBCOMMAND ...   # Chef Compliance commands
  inspec detect                      # detect the target OS
  inspec exec PATH(S)                # run all test files at the specified PATH.
  inspec help [COMMAND]              # Describe available commands or one spe...
  inspec init TEMPLATE ...           # Scaffolds a new project
  inspec json PATH                   # read all tests in PATH and generate a ...
  inspec shell                       # open an interactive debugging shell
  inspec supermarket SUBCOMMAND ...  # Supermarket commands
  inspec version                     # prints the version of this tool

Options:
  [--diagnose], [--no-diagnose]  # Show diagnostics (versions, configurations)
```

# Examples

* Only accept requests on secure ports - This test ensures that a web server is only listening on well-secured ports.

```ruby
describe port(80) do
  it { should_not be_listening }
end

describe port(443) do
  it { should be_listening }
  its('protocols') {should include 'tcp'}
end
```

* Use approved strong ciphers - This test ensures that only enterprise-compliant ciphers are used for SSH servers.

```ruby
describe sshd_config do
   its('Ciphers') { should eq('chacha20-poly1305@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr') }
end
```

* Test your `kitchen.yml` file to verify that only Vagrant is configured as the driver.  The %w() formatting will
pass rubocop linting and allow you to access nested mappings.

```ruby
describe yaml('.kitchen.yml') do
  its(%w(driver name)) { should eq('vagrant') }
end
```

Also have a look at our examples for:
- [Using Chef InSpec with Test Kitchen & Chef Infra](https://github.com/chef/inspec/tree/master/examples/kitchen-chef)
- [Using Chef InSpec with Test Kitchen & Puppet](https://github.com/chef/inspec/tree/master/examples/kitchen-puppet)
- [Using Chef InSpec with Test Kitchen & Ansible](https://github.com/chef/inspec/tree/master/examples/kitchen-ansible)
- [Implementing an Chef InSpec profile](https://github.com/chef/inspec/tree/master/examples/profile)

## Or tests: Testing for a OR b

* Using describe.one, you can test for a or b.  The control will be marked as passing if EITHER condition is met.

```ruby
control 'or-test' do
  impact 1.0
  title 'This is a OR test'
  describe.one do
    describe ssh_config do
      its('Protocol') { should eq('3') }
    end
    describe ssh_config do
      its('Protocol') { should eq('2') }
    end
  end
end
```

## Command Line Usage

### exec

Run tests against different targets:

```bash
# run test locally
inspec exec test.rb

# run test on remote host on SSH
inspec exec test.rb -t ssh://user@hostname

# run test on remote windows host on WinRM
inspec exec test.rb -t winrm://Administrator@windowshost --password 'your-password'

# run test on docker container
inspec exec test.rb -t docker://container_id

# run with sudo
inspec exec test.rb --sudo [--sudo-password ...] [--sudo-options ...] [--sudo_command ...]

# run in a subshell
inspec exec test.rb --shell [--shell-options ...] [--shell-command ...]

# run a profile targeting AWS using env vars
inspec exec test.rb -t aws://

# or store your AWS credentials in your ~/.aws/credentials profiles file
inspec exec test.rb -t aws://us-east-2/my-profile

# run a profile targeting Azure using env vars
inspec exec test.rb -t azure://

# or store your Azure credentials in your ~/.azure/credentials profiles file
inspec exec test.rb -t azure://subscription_id
```

### detect

Verify your configuration and detect

```bash
id=$( docker run -dti ubuntu:14.04 /bin/bash )
inspec detect -t docker://$id
```

Which will provide you with:

```
{"family":"ubuntu","release":"14.04","arch":null}
```

## Testing Chef InSpec

We offer `unit`, `integration`, and `aws` tests.

- `unit` tests ensure the intended behaviour of the implementation
- `integration` tests run against Docker-based VMs via test-kitchen and [kitchen-inspec](https://github.com/chef/kitchen-inspec)
- `aws` tests exercise the AWS resources against real AWS accounts

### Unit tests

```bash
bundle exec rake test
```

If you like to run only one test file:

```bash
bundle exec m test/unit/resources/user_test.rb
```

You may also run a single test within a file by line number:

```bash
bundle exec m test/unit/resources/user_test.rb -l 123
```

### Integration tests

These tests download various virtual machines, to ensure Chef InSpec is working as expected across different operating systems.

These tests require the following gems:

- test-kitchen
- kitchen-dokken
- kitchen-inspec

These gems are provided via the `integration` group in the project's Gemfile.

In addition, these test require Docker to be available on your machine or a remote Docker machine configured via the standard Docker environment variables.

#### Running Integration tests

List the various test instances available:

```bash
bundle exec kitchen list
```

The platforms and test suites are configured in the `.kitchen.yml` file. Once you know which instance you wish to test, test that instance:

```bash
bundle exec kitchen test <INSTANCE_NAME>
```

You may test all instances in parallel with:

```bash
bundle exec kitchen test -c
```

### AWS Tests

Use the rake task `bundle exec rake test:aws` to test the AWS resources against a pair of real AWS accounts.

Please see [TESTING_AGAINST_AWS.md](./test/integration/aws/TESTING_AGAINST_AWS.md) for details on how to setup the needed AWS accounts to perform testing.

### Azure Tests

Use the rake task `bundle exec rake test:azure` to test the Azure resources against an Azure account.

Please see [TESTING_AGAINST_AZURE.md](./test/integration/azure/TESTING_AGAINST_AZURE.md) for details on how to setup the needed Azure accounts to perform testing.
