I am trying to update a discontinued package called [MatlabCompat.jl](https://github.com/MatlabCompat/MatlabCompat.jl).
First, I ran [my forked FemtoCleaner](https://github.com/aminya/FemtoCleaner.jl) locally to update the deprecated syntax, and here is the result: [Updated MatlabCompat.jl](https://github.com/aminya/MatlabCompat.jl).
However, as I mentioned [here in my pull request](https://github.com/MatlabCompat/MatlabCompat.jl/pull/16), I can not add the updated package, and I get errors for “Unsatisfiable requirements detected for package Tk”.
My question is: How can I add a package like this and debug and test its various aspects. It seems very hard to be able to update the syntax inside a package without having a way to test it.

What I usually do is to clone my package into the `.julia/dev` using git and then do `dev MyPackage` in package mode.
For other paths, you should be able to use
```julia
(v1.1) pkg> dev path/to/mypackage
```
