I’ve been using the same plugin (available to install via IDEA Plugins) and it does have problems. I was using version 14.0, but updated right now to 14.0.1. I see that on GitHub there exists newer versions too, but for some reason they are not available to install directly from my IDEA. My IDEA is not up to date as well, maybe that’s the reason.
But right now tried to set a breakpoint into the code and run tests with debugger - it does not even start running tests, but waits forever until debugger attaches. Some time ago I was able to set a breakpoint, but not evaluate anything when breakpoint was reached - it just crashed Elixir/Erlang process.
I don’t know what I’m doing wrong, but for me this plugin is still nothing more than just a glorified syntax highlighter as mentioned before. And even this is happening sometimes really-really slow - when I open a file then I can actually see how syntax is getting highlighted line by line.
