# E2E tests build and run Actors on the platform. The combination of max-parallel 4 with 16 pytest
# workers and a global concurrency group is a compromise between stability and performance - it keeps
# the platform's resource usage in check while still allowing reasonable test throughput.

# E2E tests build and run Actors on the platform. Limit parallel workflows to 1 to avoid exceeding
# the platform's memory limits. A single workflow with 16 pytest workers provides good test
# parallelization while staying within platform constraints.
