Unit Tests
Rust and Cargo come with a simple unit test framework:
-
Unit tests are supported throughout your code.
-
Integration tests are supported via the
tests/
directory.
Tests are marked with #[test]
. Unit tests are often put in a nested tests
module, using #[cfg(test)]
to conditionally compile them only when building tests.
- This lets you unit test private helpers.
- The
#[cfg(test)]
attribute is only active when you runcargo test
.
Speaker Notes
This slide should take about 5 minutes.
Run the tests in the playground in order to show their results.
