Options:
  --import-base   Change base of import paths with --print-imports      [string]
  --magic, -m     Make "test" available as a global                    [boolean]
  --pattern, -p   Regex pattern for matching test files                 [string]
  --print-imports Print imports to test files instead of running       [boolean]
  --require, -r   Preload the specified module at startup               [string]
  --serial, -s    Run tests sequentially, not in parallel              [boolean]
