Sway aims to provide facilities for both unit testing and integration testing.
Unit testing refers to "in-language" testing which can be triggered via the
forc test command. Sway unit testing is currently a high-priority
work-in-progress, you can follow along at this
issue Icon Link.
Integration testing refers to the testing of your Sway project's integration
within some wider application. You can add integration testing to your Sway+Rust
projects today using the cargo generate template and Rust SDK.
