Needs code coverage evaluation #1685

codechain needs code coverage evaluation before releasing version 2.0 Firstly, we need to investigate the coverage measuring tool.

kcov does not help and the repository is too old.

tarpaulin is much better. Even though the cargo test --all passes successfully, tarpaulin gives error like

test consensus::validator_set::dynamic_validator::tests::validator_set ... Error: "Failed to get test coverage! Error: Failed to run tests: A segfault occurred while executing tests"

grcov finally works with

RUSTFLAGS="-Zprofile -Ccodegen-units=1 -Cinline-threshold=0 -Clink-dead-code -Coverflow-checks=off -Zno-landing-pads" cargo +nightly test --all;
zip -0 ccov.zip `find . \( -name "codechain*.gc*" \) -print`;
grcov ccov.zip -s . -t lcov --llvm --branch --ignore-not-existing --ignore-dir "/*" -o lcov.info;

But still It counts test functions' lines, I need to study more about ignore test functions from counting.
