The --no-compile flag and gas report completeness

[davidtperk]

hardhat-gas-reporter produces complete gas reports for hh test --no-compile but excludes my contracts for hh test run without the --no-compile flag. Unable to pinpoint a root cause and don't have a reproducible example yet, but wanted to check if there are known issues why compilation might cause hardhat-gas-reporter to miss contract calls. Other plugins in use that may be relevant include hardhat-abi-exporter, hardhat-solpp, and hardhat-dependency-compiler.

Oh interesting. Do you mean you only get a partial report and newly compiled contracts are missing?

The plugin loads compilation artifacts as part of a mocha configuration step (I'd guess this must happen before auto-compilation). And it uses hre.artifacts supplied to it by an over-ridden subtask: TASK_TEST_RUN_MOCHA_TESTS

(Just leaving a note for myself that this is where we bind that for consumption in the mocha reporter at eth-gas-reporter).

Line 184 in 104db50

options.getContracts = getContracts.bind(null, hre.artifacts, options.excludeContracts);

Precisely. hh compile && hh test --no-compile works, but not hh test.

console.log(hre.artifacts._validArtifacts) just above the line you linked to (but in index.js) returns []with --no-compile and a long array of artifacts without --no-compile.

Ah! Thanks for reporting and looking at that. Not sure what to do about this off the top of my head....
