0.8.7

What's Changed

viaIR now allowed

This release (hopefully) fixes a long-running problem solidity-coverage had with solc's viaIR compilation mode - It's now possible to use it without any special configuration. (Please report any ongoing issues with this to issue #861)

If you've been using .solcover.js options like configureYulOptimizer and solcOptimizerDetails as a work around, you should remove them when upgrading. (Don't forget to run the hardhat clean task after updating any coverage config stuff).

--network no longer allowed

Sadly the ganache client has been deprecated. The coverage plugin never worked with its latest major version and the network flag only existed for its sake. Going forward, the network option throws an error notifying the user that coverage only uses the HardhatEVM network.

--sources cli option

You can now select a single file (or folder) at the command line to generate coverage for. This option should speed things up if you've been waiting for the plugin to instrument everything in a large project whenever you run the command.

$ npx hardhat coverage --sources MyFile.sol
$ npx hardhat coverage --sources MyFolder

(Thanks so much @clauBv23 for adding this!)

Funding

OpenZeppelin has very generously funded recent work at solidity-coverage via DRIPS, a public goods protocol which helps you direct money to projects in your dependency tree. Thanks so much! ❤️
