Benefits of this approach:
1. Defect approach
2. Easy to understand

Step 1:
Spread test load across workers in CI by splitting test files
into small execution groups using a naive bash script.

Step 2:
Enable cross-browser coverage without CI spend or extra round-trips to the AUT
By using the Applitools Ultrafast Grid

Benefits with this approach:
1. More reliable test runs (1 trip to AUT)
2. Wider coverage w/o increased execution times
3. Solution that can be extended (e.g., a11y)
Problems with this approach:
1. Requires some initial setup
2. Only supports web
