can not override config when run:multi #1754

What are you trying to achieve?

codeceptjs run-multiple xxxx

the multiple browser config should override original config

What do you get instead?

when the config value is a false value, it can not be override

Refer to code here: https://github.com/Codeception/CodeceptJS/blob/5fb0f6a787d93fc641d711fdf4cd74d3132829e0/lib/command/run-multiple.js#L200

when obj[key] === 0, the new value (for example, 1) will not be assigned.

Possible fix:

if (obj[key] !== undefined) obj[key] = value;

Provide test source code if related

Sample codecept.conf.js

{
  config: {
    helpers: {
      WebDriver: {
        timeouts: 0
      }
    }
    multiple: {
      example: {
        browsers: [{
          timeouts: 1
        }]
      }
    }
  }
}

codeceptjs run-multiple example , the subprocess received args: --override '{"helpers": {"WebDriver": {"timeout": 0}}}' , but we expect timeout: 1
