Use the verifier directly

[
  # from_url, to_url
  %w[http://example.com/jacobburenstam https://jacobburenstam.com/]
  # ...
].each do |data|
  from, to = data
  result = verifier.call(from, to)

  result.success # => false
  result.start_url # => 'http://example.com/jacobburenstam'
  result.expected_redirect # => 'https://jacobburenstam.com/'
  result.redirected_to # => nil
end

verifier.results.length # => 1
```

From CSV-files

```ruby
# input_path - must be a CSV file with two columns: from_url, to_url (order doesn't matter)
VerifyRedirects.from_csv(input_path: input_path, output_path: output_path) do |result|
  unless result.success
    puts "Failed redirect for #{result.start_url}"
  end
end
```
