I'm attracted to the FinancialForce apexmocks and related libraries, and have successfully deployed to Trailhead playgrounds, Dev sandboxes and our full sandboxes. The deployments ran quite smoothly and quickly. When I went to deploy apexmocks to our Production instance, the status doesn't move past Status: Queued. Are there settings that I should check in Production to see why there's such a difference?
I will try again in the wee hours, but I tried yesterday afternoon, (relatively) early this morning and ~2:00 p.m. EST, and I see neither progress nor errors.
