I am wondering if PHPStorm can be configured to exclude the test folder from percent since my module has 100% coverage, but the Test folder brings the total value up to 50%.

This may not be related, but I also have a problem where the coverage window never displays the actual coverage data, neither on a separate tab, nor on viewing the file itself.

Most likely, I misconfigured something, or is it somehow related to my project setup (Magento project based on a composer with symbols), but I hit my head a little against the wall. Any suggestions are welcome.

The reason I thought PHPStorm was because the version of the HTML coverage worked fine excluding the test folder correctly.
