@fabianorodrigo Which version of solidity-coverage are you using? Can you run:

npm list solidity-coverage

[cgewecke]

@fabianorodrigo Going through these in order. . .I'm using Truffle v5.0.26 and solidity-coverage 0.6.3. I'm adding a coverage network to the truffle-config.js per the README instructions and at the command line running

npx solidity-coverage

1. Golem (with no additional configuration)

2. https://github.com/nicholashc/MerkleShip/truffle

Bad link.

[cgewecke]

3. Matic Networks

Not sure what's going on here but it instrumented fine. Seems to be missing a .csv file and would require some additional project specific configuration. This project also has native solidity tests which are not supported, but they seem to have compiled ok. And as a precaution I commented out the mocha eth-gas-reporter config because coverage and that tool are not really compatible.

[cgewecke]

@fabianorodrigo I can't duplicate your errors. It would be helpful if you provided clear reproduction steps for one project - e.g linked to a fork where you have installed coverage, which I can clone and run a command that results in the same error you're seeing

Closing.

@fabianorodrigo Which version of solidity-coverage are you using? Can you run:

npm list solidity-coverage

I'm using:

Linux Mint 19.1 Truffle v5.0.27 (core: 5.0.27) Solidity - 0.5.3 (solc-js) Node v10.15.3 Web3.js v1.0.0-beta.37 solidity-coverage: 0.6.3

[fabianorodrigo]

@cgewecke, I'm sorry. I found out my mistake. A few weeks ago I cloned solidity-coverage and used 'npm link' in order to use it as dependency. So I wasn't actually running version 0.6.3. I'm going to repair this and report if I found something else.

[cgewecke]

@fabianorodrigo Ah that makes sense! Thank you anyway for testing a wide array of projects, it's super helpful.

and report if I found something else
