/// Run the Sway unit tests for the current project.
///
/// NOTE: Previously this command was used to support Rust integration testing, however the
/// provided behaviour served no benefit over running `cargo test` directly. The proposal to change
/// the behaviour to support unit testing can be found at the following link:
/// https://github.com/FuelLabs/sway/issues/1833
///
/// Sway unit tests are functions decorated with the `#[test]` attribute. Each test is compiled as
/// a unique entry point for a single program and has access to the namespace of the module in
/// which it is declared.
///
/// Unit tests decorated with the `#[test(script)]` attribute that are declared within `contract`
/// projects may also call directly into their associated contract's ABI.
///
/// Upon successful compilation, test scripts are executed to their completion. A test is
/// considered a failure in the case that a revert (`rvrt`) instruction is encountered during
/// execution. Otherwise, it is considered a success.
