When I open the coverage report generated with `bundle exec rake minitest`
Then I should see the groups:
| name | coverage | files |
| All Files | 80.0% | 1 |
| All Files | 85.71% | 3 |

Scenario:
Given SimpleCov for Minitest is configured with:
"""
require 'simplecov'
SimpleCov.start
"""

When I open the coverage report generated with `bundle exec ruby -Ilib:minitest minitest/other_test.rb`
Then I should see the groups:
