How to install 0.7.0

Install

$ npm install --save-dev solidity-coverage

Add this package to your plugins array in truffle-config.js

module.exports = {
  networks: {...},
  plugins: ["solidity-coverage"]
}

Run

truffle run coverage [command-options]

A full list of options and other information are available here

Upgrading from 0.6.x to 0.7.x

First, follow the installation instructions and see if it works.

🐇 It does!? Bye.

🐘 It does not.

Are you using Truffle V5?

• Everything works best with Truffle versions >= 5.0.31.

Are you launching testrpc-sc yourself as a stand-alone client?

• Stop launching it. The coverage plugin needs to initialize the client itself so it can hook into the EVM.

• By default it uses the ganache bundled with Truffle, but you can use any version (see below).

Were you passing testrpc-sc lots of options as flags? 🇯🇵 🇯🇵 🇯🇵 🇯🇵 🇯🇵

• If the flags were allowUnlimitedContractSize, gasLimit, gasPrice or emitFreeLogs, you can safely ignore them. Ditto if your port was 8555.

• If the flags were things like --account or -i, you'll need to transfer them as ganache-core options to the providerOptions key in .solcover.js.

• Ganache's "cli flag" and "js option" formats are slightly different. Check out their docs

  Example

  Before (at the command line)

  $ testrpc-sc --account="0x2b...7cd,1000000000000000000000000" -i 1999 --noVmErrorsOnRPCResponse
  

  Now (in .solcover.js)

  providerOptions: {
    accounts: [{
      secretKey: "0x2b.............7cd",
      balance: "0xD3C21BCECCEDA1000000"   // <-- Must be hex
    }],
    network_id: 1999,
    vmErrorsOnRPCResponse: false
  }
  
  

Do you have a 'coverage' network in truffle-config.js?

• If you copy-pasted it from the <= 0.6.x docs, you can safely delete it.

• You should be able to truffle run coverage --network <network-name> and use the same config you run your regular tests with.

• You can also omit the network flag and you'll be given default settings which look like this:

  'soliditycoverage': {
    port: 8555,
    host: "127.0.0.1",
    network_id: "*",
  }
  

Do your tests depend on the specific ganache version you have as a local dependency?

• Declare it in .solcover.js using the client option

  client: require('ganache-cli'),
  

Does your config contain any deprecated options?

• They are:

  accounts,       # Now: `providerOptions: { total_accounts: <number> }`
  buildDirPath,   # Now: `--temp <path>` (At the command line, see Advanced Use)
  copyPackages,
  copyNodeModules,
  deepSkip,
  testCommand,
  compileCommand,
  noRpc
  

• You can delete them.

Do you usually: (1) launch testrpc-sc, (2) do something special, (3) run solidity-coverage?

• See the workflow hooks documentation. The "something special" will likely need to run within an async function declared in .solcover.js

Are you what some might call an 'advanced user'?

🎉 It's still not working!! 🎉

• If your project is public, please open an issue linking to it and we will advise and/or open a PR into your repo installing solidity-coverage after patching any relevant bugs here.

• If your project is private, see if you can generate a reproduction case for the problem and we'll try to fix that.
