Possible to report coverage to console and html?

[Allen Bierbaum]

I am looking into using Karma for one of our projects and have been evaluating it.

So far I love the integration but ran into a problem with the coverage reporting.  Namely I can get the text summary to show in the console which is great for showing users quick feedback, but when I do that I can't find a way to also generate the HTML report so people can go see the details.

My example is here: https://github.com/abierbaum/test_karma/tree/report_question

Is there a way to configure coverage so that it both writes a summary to the console and creates a full html report?

On a related question would it be possible to have the report generator for the full HTML report print a full file path to the report on the console?  That would make it much easier for developers to click on the link to get to the full details to track down places they want to improve coverage.

Thanks,

Allen

Did you see http://karma-runner.github.io/0.8/config/coverage.html ? Make sure you configure the reporter to generate html output and you should be fine.

Btw, I recommend only running coverage as a separate build not during development, as it slows down and makes debugging harder (each file has to be preprocessed).

I was able to get HTML output working, but not HTML and text summary at the same time.  I forked karma-coverage and created a pull request that allows multiple reporters to be configured for the same run.  See: https://github.com/karma-runner/karma-coverage/pull/6

With this change I can get HTML and text summary output together.

Understood.  I came up with a workaround for our grunt-basd build.  I am not sure if it is a good idea or not, but what I did is to create two testing tasks.  The first one runs unit tests normally, then the second one will run coverage using phantomjs in 'singleRun' mode to generate coverage information (summary text and generated HTML to see details and track down areas to further test).  This lets the tests run normally and support debugging normal unit tests to run for debugging 

If anyone is interested in the details, there is a simple example here: https://github.com/abierbaum/test_karma/blob/dev/karma_canary/Gruntfile.js

It seems to work pretty well although sometimes I end up with several phantomjs processes in the background if I use PhantomJS as the browser for the karma:unit background process.  When I switch this over to Chrome it seems to work a bit better.  If anyone has a better idea how to do this I am open to suggestions.

Anyway, thanks again for the great tool.  Looking at some of the new features in 9.x I am excited to see what people can do in the future.
