Error running karma test: jquery required

I am new to using karma and unit testing in general. I tried to find a solution by doing this problem, but I couldn't find anything useful since my app / assets / components don't have any jquery files, whatever, and I don't have bower_components. If it helps, I am using ruby ​​on rails with angular js together.

errors:
