Code coverage
|

---
|

|

To generate code coverage statistics, run kcov via Docker:
|
||||
To generate code coverage statistics, install cargo-cov. Note: the tool currently only works
|
||||
in Rust nightly.
|
||||
|
||||
```bash
|
||||
$ ./ci/coverage.sh
|
||||
$ cargo +nightly install cargo-cov
|
||||
```
|
||||
The coverage report will be written to `./target/cov/index.html`
|
||||
|
||||
Run cargo-cov and generate a report:
|
||||
|
||||
```bash
|
||||
$ cargo +nightly cov test
|
||||
$ cargo +nightly cov report --open
|
||||
```
|
||||
|
||||
The coverage report will be written to `./target/cov/report/index.html`
|
||||
|
||||
|
||||
Why coverage? While most see coverage as a code quality metric, we see it primarily as a developer
