Is there any way to stop Karma serving cached files?

Question

So here's my issue. I'm trying to run a test suite for an old application of mine. However, I've stumbled upon the notorious Karma error: Executed 0 of 0 ERROR.

As I turn Karma's loglevel to debug, I realize that these lines are being printed:

DEBUG [web-server]: serving:     /home/**/**/**/node_modules/karma/static/context.html

As you can tell, there are no specs. I try to add a spec file to the files array inside karma.conf.js, but to no avail. The same files are printed.

I'm assuming my problem is related with said caching.

Any help will be deeply appreciated.

All the best,

Alejandro

4 years late, but according to the karma file definition you can set the nocache-attribute to true.

In case your file-definition in the karma.conf.js looks like this:

files: ['src/app/scripts/app.js']

you should change it to

files: [pattern: 'src/app/scripts/app.js', nocache: true]

This will stop serving the files from cache.
