deterministic-unittest-coverage
===========================
A tool to check for non-determinism in unit-test coverage. To get the help, run:
```
RUST_BACKTRACE=1 cargo run --manifest-path ./contrib/devtools/deterministic-unittest-coverage/Cargo.toml -- --help
```
To execute the tool, compilation has to be done with the build options:
```
-DCMAKE_C_COMPILER='clang' -DCMAKE_CXX_COMPILER='clang++' -DCMAKE_CXX_FLAGS='-fprofile-instr-generate -fcoverage-mapping'
```
Both llvm-profdata and llvm-cov must be installed.
