描述

Allow splitting a single test suite into multiple chunks, so that it can be executed in multiple browsers and therefore executed on multiple machines or at least using multiple cores.

研究方向
The issue requests splitting test suites into chunks for parallel execution across multiple browsers or machines. The discussion in comments (43 comments) includes various approaches but no clear consensus or maintainer guidance. To start, examine the Karma test runner source code in the `lib/` directory, particularly the execution flow, to understand current test dispatch. Look at commented suggestions for sharding strategies, such as using environment variables or CLI arguments. There are no linked PRs, so this would require designing and implementing a new feature from scratch.
