描述

Expected behavior

Seeing all available options that materially affect the test harness here

Actual behavior

I don't see usePolling; which solves the problem of auto-watching mounted source files in Docker containers; cf. this SO thread.

Enviroment Details

  • Karma version (output of karma --version): 0.13.9
  • Relevant part of your karma.config.js file
    ...
    // won't work in a Docker container
    autoWatch: true,

    autoWatchBatchDelay: 1000,

    usePolling: true,
    ...

This makes it work with the following output from docker-compose logs, e.g.

研究方向
Locate the configuration file documentation at http://karma runner.github.io/0.13/config/configuration file.html. Add a section describing the 'usePolling' option, including its purpose (to enable file watching in Docker containers) and a usage example. Reference the linked Docker issue and Stack Overflow thread for context.
