Do you feel Rust features work better to implement the interface?

There are great existing tools like ReTest.jl but they require a new framework, this package acts more like a tool on top of the existing standard test framework.

All test files are run in a separate module (like in SafeTestsets.jl) and use TestEnv.jl to get the correct test environment.
For `@testset` blocks, the preamble is fetched and run before to ensure it works.

No need for a mode, it needs some fixing but the package provides hooks to the REPL (same as Revise)
