Hint:
• Cross Browser Mode allows SHAFT to run your test class against Chrome, Firefox, and Safari!
• You need to have 'Docker Desktop' installed on your machine, and configured to use Linux images.
• Off → Your tests will run normally and respect your configuration.
• Sequential → Your tests will run on Chrome, Firefox, and Safari in sequence.
• Parallelized → Your tests will run on Chrome, Firefox and Safari in parallel. And for each browser they will run in sequence.
