Description

Cobertura reporter misses methohd's names in the code coverage report. Method's names are replaced by strings like this (anonymous_0)

🔬 Minimal Reproduction

Create new app

ng new cobertura-test
cd cobertura-test

Add Cobertura reporter in karma.conf.js

...
reports: ['html', 'lcovonly', 'text-summary', 'cobertura'],
...

Run tests

ng test --code-coverage`

Then in /coverage/cobertura-test/cobertura-coverage.xml report file we can see that method's names looks like that:

<method name="(anonymous_0)" hits="3" signature="()V">

All method's names are replaced by anonymous_<some number>.

Desired funcionality

Cobertura report includes method's names.

I am also facing the same issue. Is there any solution?.

We are having the same issue with the Cobertura reports.

[EDIT] We have an issue with the html report as well, but after scaffolding a new project with the cli, the html report worked, cobertura report still did not. So it's does't seem to be related. I will keep the screenshots in here, in case there might however be a connection between both issues.


[EDIT2] After more investigation, the html report is working fine (project cleanup, ng update...), cobertura report is not, so there is no connection between both.
