Maximum number of tests scheduled in one step. Setting it to 1 will force pytest to send tests to workers one by one - might be useful for a small number of slow tests. Larger numbers will allow the scheduler to submit consecutive chunks of tests to workers - allows reusing fixtures. Unlimited if not set. Fixes pytest-dev#855

While this solves #855, it's an ugly workaround IMO. The more I look at the scheduling problem, the more I think it should be solved using work stealing https://en.wikipedia.org/wiki/Work_stealing. Described in detail in #858 |
