end

Ensure an SSH public key ID is available.

describe aws_iam_ssh_public_key(user_name: 'USER_NAME', ssh_public_key_id: 'KEY_ID', encoding: 'SSH') do
    its('ssh_public_key_id') { should eq 'SSH_PUBLIC_KEY_ID' }
end

Ensure SSH key is expired or not.

describe aws_iam_ssh_public_key(user_name: 'USER_NAME', ssh_public_key_id: 'KEY_ID', encoding: 'SSH') do

  it { should exist }
end

Use should_not to test the entity does not exist.

describe aws_iam_ssh_public_key(user_name: 'USER_NAME', ssh_public_key_id: 'KEY_ID', encoding: 'SSH') do
  it { should_not exist }
end

be_available

Use should to check if the entity is available.

describe aws_iam_ssh_public_key(user_name: 'USER_NAME', ssh_public_key_id: 'KEY_ID', encoding: 'SSH') do
  it { should be_available }
end
