Mastering Blockchain Programming with Solidity

Using solidity-coverage

The requirement for using solidity-coverage tools is that your project must have the test cases present in the truffle project. This is because all of these test cases will be executed and the corresponding Solidity code will be instrumented by the tool.

The following is the command to run the solidity-coverage tool in the truffle project. If this reports any error, ensure that your test cases are working with the truffle test command, because this command will be initiated by the solidity-coverage tool internally:

$ ./node_modules/.bin/solidity-coverage

The preceding command will internally start the testrpc instance (testrpc is the old name of ganache-cli) on port number 8555, run all of the test cases present for ...
