Plugin does not work with latest version of vue-cli

[scottbedard]

With the latest version of vue-cli, it appears that the webpack config is not being passed to karma anymore. The test:unit command fails with the following output...

yarn run v1.9.4
$ vue-cli-service test:unit
07 02 2019 10:52:59.549:ERROR [preprocess]: Can not load "webpack", it is not registered!
  Perhaps you are missing some plugin?

START:

Any help with this issue would be appreciated!

Update: Just investigated this a bit, and it appears that things stopped working with vue-cli 3.1.0

Here is a new plugin I created since this repository has become inactive now: https://github.com/tushararora/vue-cli-plugin-unit-karmajs
