## 🐛 Troubleshooting
|
|
|
|
### Coverage shows 0%
|
|
```bash
|
|
export RUSTFLAGS="-C instrument-coverage"
|
|
cargo clean
|
|
cargo llvm-cov --workspace
|
|
```
|
|
|
|
### Test script fails
|
|
```bash
|
|
# Check dependencies
|
|
cargo install cargo-llvm-cov
|
|
sudo apt-get install jq bc
|
|
|
|
# Verify installation
|
|
cargo-llvm-cov --version
|
|
jq --version
|
|
bc --version
|
|
```
|
|
|
|
### Module not tracked
|
|
```bash
|
|
# Verify package name
|
|
cargo metadata --no-deps | jq '.packages[].name'
|
|
|
|
# Run manual coverage
|
|
cargo llvm-cov --package <name> --html
|
|
```
