Unable to integrate solidity-coverage to a framework. Receiving ''no such file or directory, open './allFiredEvents' error

We’re developing a tool called etherlime, which is basically an ethereum development and deployment framework based on ethers.js. We want to integrate solidity-coverage in it. However, we always get this error:

Event trace could not be read.
Error: ENOENT: no such file or directory, open './allFiredEvents'
Exiting without generating coverage...

In order to run the solidity-coverage I have created the following function

const runWithCoverage = async () => {
	var accountsData = ''
 	accounts.forEach(account => {
		let accountData = `--account "${account.secretKey},${account.balance.replace('0x', '')}" `;
		accountsData += accountData;
	});
	
	config["testrpcOptions"] = `${accountsData}`;
	const app = new App(config);
	app.generateCoverageEnvironment();
	app.instrumentTarget();
	app.launchTestrpc()
		.then(() => {
			app.runTestCommand();
			app.generateReport();
		})
		.catch(err => log(err));
}

The config variable contains the following object:

{
    "compileCommand": "etherlime compile --runs=999",
    "testCommand": "etherlime test",
    "copyPackages": ["zeppelin-solidity"],
    "port": 8545,
    "buildDirPath": "/build"
}

When the code is executed it uses by default testrpc-sc which comes from solidity-coverage. However, I keep getting the above error. Any ideas or advice will be very helpful.

Currently, the case can be tested using the etherlime with the etherlime-coverage branch here. There is a test project which can be used too.

Is it possible to integrate solidity-coverage in a framework like ours? The compilation process of the smart contracts in etherlime is based on truffle compile and the generated json files from our framework are the same.

@Perseverance Fantastic! Nice work.

@cgewecke Yes, It is working now. I rewrote the unit tests we were using and suddenly all started working. Etherlime now has an integrated solidity-coverage inside via the etherlime coverage command 😉
