I’m describing my test-specific dependencies (julia 1.4) in `test/Project.toml` [according to the docs](https://julialang.github.io/Pkg.jl/v1/creating-packages/#Test-specific-dependencies-in-Julia-1.2-and-above-1). It’s also mentioned in the docs that:
> Pkg will add the tested package itself implictly
I’d like however to be able to easily run my test scripts independently from `Pkg.test` for greater flexibility. I tried therefore adding an explicit dependency to the package I’m developing in `test/Project.toml`, since after all it sounds like something that `Pkg` does anyway when testing.
Sure enough, I can now run my test scripts independently. However when I actually use them through `Pkg.test` I get the following error:
```julia
ERROR: can not merge projects
```
Is this a feature or a bug?
Is there a better way to do what I want to do?
Thanks! 😃

Ummm, for all my modules I have Test as a dependency in the `test/Project.toml` file and I don’t have issues. Do you get some sort of stack trace?

I’m not referring to `Test`, but to the package I’m testing.
I’m developing package `X`. `test/Project.toml` looks like:
```julia
[deps]
Test = "8dfed614-e22c-5e08-85e1-65c5234f0b40"
CSV = "336ed68f-0bac-5ca0-87d4-7b16caf5d00b"
Plots = "91a5bcdd-55d7-5caf-9e0b-520d859cae80"
X = "db654dba-670c-566a-9226-64313b881ded"
```
I’m talking about the last line: having the under development package `X` as a dependency in its own test environment.

Sorry, I understand now. You might be able to do something like:
```julia
using Pkg
Pkg.activate("test")
Pkg.develop("/path/to/X")
Pkg.instantiate();
include("runtests.jl")
Pkg.rm("X")
```
I’m not 100% that will work though.

it looks that it is indeed a bug: [https://github.com/JuliaLang/Pkg.jl/issues/1585](https://github.com/JuliaLang/Pkg.jl/issues/1585)
