A couple of times, when testing a package, I realized that although I thought a call was dispatching to a method in the package, it was actually dispatching to a fall-back method in `Base`.

So I wrote macros to test that a call dispatches to the method in your package. These are collected in [MethodInSrc.jl](https://github.com/jlapeyre/MethodInSrc.jl). See the README for more details.

I announced this package six years ago. It was either never registered, or was purged. It never had a `Project.toml` till a couple of days ago. I am announcing again because it is now in the General registry.

Examples of use in an unregistered package is here [IdentityMatrix.jl/test/runtests.jl at main · jlapeyre/IdentityMatrix.jl · GitHub](https://github.com/jlapeyre/IdentityMatrix.jl/blob/main/test/runtests.jl)

If I recall correctly, when preparing to register the package, the code from six years ago worked without modification. This is because it uses `InteractiveUtils`, which has been stable.
