Instead of writing a large number of yaml test suites and committing them to the mongodb/mongo repository, we will use Evergreen’s generate.tasks feature to programmatically generate them. These generated tasks will run our desired test suites with the three different version configurations. Generating the tasks will take advantage of the existing evergreen_generate_resmoke_tasks.py script, which is used to split test suites up into smaller chunks subject to a target wall-clock runtime.
