After using test frameworks like ZIO Test in Scala for years, Rust's built-in testing capabilities feels limited. To fill the missing gaps I wrote a new test framework called test-r. In this talk I will show some of the features test-r brings to the Rust ecosystem, how they are implemented, how they are used in the test suite for Golem Cloud, and show the tradeoffs made in order to emulate the built-in test framework - possibly the most important aspect of this new library.
