Missing `List.vue` file in coverage report

[vitoravelino]

Hello there!

I pulled the code, ran npm install and List.vue does not appear in the coverage report files. Is that expected?

Also, I passed --reporter=html to check the output in the browser and when I opened the vue file I got:

Unable to lookup source: /home/vitoravelino/Workspace/others/vue-test-utils-mocha-webpack-example/src/components/MessageToggle.vue?d4b1857c(ENOENT: no such file or directory, open '/home/vitoravelino/Workspace/others/vue-test-utils-mocha-webpack-example/src/components/MessageToggle.vue?d4b1857c')

I had the same problem! I found the issue answered here in the nyc issue page. Looks like if you change devtool: 'inline-cheap-module-source-map' to devtool:'eval' in webpack.config.js it works! Although, this is not what mocha-webpack recommends in their documentation it seems to be a good workaround. The inline-cheap-module-source-map seems to be incompatible with .vue files.

Thanks for the tip, @dbschwartz. I'll check that out later!

No prob @vitoravelino! It's actually devtool not dev. My bad. I fixed the original post
