Test coverage report not working.

[xereda]

The test coverage report is not working. Terminal details and html report, both are not being generated.

I created a project with vue cli 3.0 to do the tests. Available in github: https://github.com/xereda/vue-3.0

Commands executed:

npm run test:unit -- --coverage  
// vue-cli-service test:unit "--coverage"

npm run test:unit -- --coverage --watch
//  vue-cli-service test:unit "--coverage" "--watch"

Report not generated:

Any solution to this? I just tried a new project

npx @vue/cli@3 create cli3-test and then in cli3-test running npm run test:unit -- --coverage I'm getting the same results.

Thx

I'd like to chime in here, I'm facing essentially the same problem, currently with vue-jest 3.0.5 I can't get any coverage report for vue files. all I get are for js files.
On a separate project I have no problems with coverage, but it's using 4.0.0 beta 2.
On this current project I'm unable to upgrade as I'm getting errors in compilation of the templates (I'm using @nuxt/style-resources module to include some scss variable in my templates and for some reason this is not picked up and fails abruptly).
Any suggestion/tip, is greatly appreciated!

Just an update if anyone's following this issue: as explained in another issue (#217) the problem seems to be related to latest version of jest v25. Downgrading seems to be a decent enough workaround to this problem for the meantime

Downgrading to 24.9.0 fixes the issue, now I have my vue components shown in the test coverage
table

Provably it's a same issue with #217.
I'll close this one. If you think this is another issue, please reopen.
