@qinghua0120 solidity-coverage is a development dependency you install in a truffle project.

Example installation

mkdir myProject
cd myProject
truffle init
npm init
npm install --save-dev solidity-coverage

[guoguo0406]

@cgewecke
I am not use the truffle.
Currently i use the Remix to make a smart contract and pass the testing on ropsten.
I want to use the solidity-coverage to check the code of smart contract.
Can u use it in windows 10?

[cgewecke]

How are you testing your contracts? The tool runs your unit tests and reports which lines of your contracts were executed during them. There are some notes about running on Windows in the README.

[guoguo0406]

I testing it via the metamask, call the contract between different account. But i think the testing is not enough, so i try to find some tools to do the code testing.
The unit test case should write by myself?

[cgewecke]

Yes exactly @qinghua0120. Truffle is a common tool people use and for various reasons solidity-coverage currently assumes your project is organized with it.

Other ethereum testing frameworks you might be interested in:

• 0xProject (they have their own coverage tool).
• Embark - it might be possible to adapt solidity-coverage to evalute its tests, not sure.
• Buildler - this tool is designed to be truffle-compatible and it probably could use solidity-coverage pretty easily.

I would encourage you just to write tests in a framework you like and validate your code that way. Code coverage is useful for audits and if you're really concerned that your tests are hitting every line of your code. But it's just a measurement.

[cgewecke]

I'm going to close this because it seems like your installation issue related to not installing within the context of a solidity project.
