I am trying to unit test a very simple web-component. I don'ty know what would be some of recommended tools for that. At this moment I am trying by using wct and I am facing some issue that I didn't find anyone facing same issue. That said, I am not sure if I choose an appropriated tool for my test or I am using it incorrectly.
So, my straight question is: why I am getting "chrome failed to maximize" during such simple test. An additional and highly appreciated comment will be whatelse others are using for their own webcomponent test.
Console:
# wct --npm test -l chrome

[BABEL] Note: The code generator has deoptimised the styling of undefined as it exceeds the max of 500KB.
