//! Utilities to test Starlark code execution, using the [`Assert`] type and top-level functions.
//!
//! There are two general approaches. You can either use the functions in this module directly, e.g.:
//!
//! ```
//! use starlark::assert;
//! assert::eq("1+2", "3");
//! ```
//!
//! Or create an [`Assert`] object, which supports the same assertions, but also let's you modify the
//! environment in which the tests are run, e.g.:
//!
//! ```
//! use starlark::assert::Assert;
//! use starlark::syntax::Dialect;
//!
//! let mut a = Assert::new();
//! a.dialect(&Dialect::Standard); // Use standard Starlark
//! a.eq("1+2", "3");
//! ```
//!
//! The tests in question may be run multiple times, in different modes, to maximise test coverage.
//! For example, execution tests are run at different garbage collection settings. Parsing tests are run
//! with both Unix and Windows newlines.
