Improve CLI report

[chris-rock]

Description

After we merged #946 the reporting has been improved a lot. Still we have to cover some cases, where the report is not displaying all values properly:

### InSpec and Platform Version

0.32.0

Replication Case

# you add controls here
control "tmp-1.0" do
  impact 0.7
  title "Create /tmp directory"
  tag data: "temp data"
  tag "security"
  ref "Document A-12", url: 'http://...'

  describe file('/tmp') do                  # The actual test
    it { should be_directory }
    it { should_not be_directory }
  end
end

control "tmp-1.1" do
  impact 0.7
  title "Second test"
  desc "An optional description..."

  describe file('/tmp') do
    it { should be_directory }
  end
end

describe file('/tmp') do
  it { should be_directory }
  it { should_nota be_directory }
end

# you can also use plain tests
describe file('/tmp') do
  it { should be_directory }
end

Possible Solutions

Update the reporter to capture those cases.

@chris-rock what would the desired output be for the it { should_nota be_directory } case? marked as skipped and have some kind of error message?

[vjeffrey]

for syntax errors: mark as failed and print exception message. controls output: single passed test case missing checkmark

[chris-rock]

We have to issues:

• Exception messages are not displayed
• success messages do not get a checkmark, if a control includes only one test
