maxConcurrency

• Type: number
• Default: 5
• CLI: --max-concurrency=10, --maxConcurrency=10

The maximum number of tests and hooks that can run at the same time when using test.concurrent or describe.concurrent.

The hook execution order within a single group is also controlled by sequence.hooks. With sequence.hooks: 'parallel', the execution is bounded by the same limit of maxConcurrency.
