Can confirm this is happening with brownie as well

The coverage command just hangs out and never ends lowering it to ganache 6 (ganache-cli) works

Mentioning this as I wasted many hours trying to figure this one out and hopefully this saves someone the misery

solidity-coverage doesn't work well with ganache 7, which is packaged in latest Truffle 5.4.x.

To resolve:

  1. yarn add -D [email protected] (or npm install --save-dev [email protected])

  2. Create a file called .solcover.js in your working directory and add this content (or modify the existing content to include):

    module.exports = {
  client: require('ganache-cli'),
};

More info can be found here.
