Question

Using Truffle library from local node_modules.

solidity-coverage cleaning up, shutting down ganache server UnhandledRejections detected Promise { TypeError: Cannot read private member from an object whose class did not declare it at __classPrivateFieldGet (C:\Users\RahulMuwal\Downloads\smartcontract (2)\smartcontract\node_modules\truffle\node_modules\ganache\dist\node\webpack:\Ganache\core\lib\src\server.js:10:94)

Answer 1

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'),
   };
