I have a private package that I am trying to test. When I run the test suite, it fails, claiming it can’t find `CSV`:

```julia
ERROR: LoadError: ArgumentError: Package CSV not found in current path:
- Run `import Pkg; Pkg.add("CSV")` to install the CSV package.

Stacktrace:
 [1] require(::Module, ::Symbol) at ./loading.jl:887

 [6] top-level scope at none:6
in expression starting at /home/doomphoenix/.julia/dev/MoltenSaltThermodynamics/test/runtests.jl:3
ERROR: Package MoltenSaltThermodynamics errored during testing

```

This despite the fact that `CSV` is clearly listed as a dependency (in the Project.toml):

```julia
[deps]
CSV = "336ed68f-0bac-5ca0-87d4-7b16caf5d00b"
DataFrames = "a93c6f00-e57d-5684-b7b6-d8193f3e46c0"

LsqFit = "2fda8390-95c7-5789-9bda-21331edee243"
Plots = "91a5bcdd-55d7-5caf-9e0b-520d859cae80"
Statistics = "10745b16-79ce-11e8-11f9-7d13ad32a3b2"

[compat]
julia = "1"

[extras]
Test = "8dfed614-e22c-5e08-85e1-65c5234f0b40"

[targets]
test = ["Test"]

```

This does not appear to me to be expected behavior. What am I missing?

I am not the only one who has come across this either, see [https://discourse.julialang.org/t/confused-by-pkg-test-behavior/35500](https://discourse.julialang.org/t/confused-by-pkg-test-behavior/35500).  
Thanks!

A little more info would be helpful (ideally as a MWE).

Do you have, by any chance, a separate `test/Project.toml` from which `CSV` is missing? Cf [5. Creating Packages · Pkg.jl](https://julialang.github.io/Pkg.jl/v1/creating-packages/#Test-specific-dependencies-in-Julia-1.2-and-above-1)

Sorry to ask, but is has happened to me before: you are `using CSV` in `runtests.jl`?

I don’t have a separate `Project.toml` in `test`, but that is a good thing to keep in mind and something I was unaware of. Yes, I am `using CSV` in `runtests.jl`. Judging from the tone of your question, this seems to be the problem, but I’m not sure why that’s the case?

Thanks for the help.

I had exactly the same problem over the weekend, but when I went now to make a little MWE, I found the problem installing CSV had gone away. The problem only happened when you ran `Pkg.test()`; just running the tests directly from the command line worked fine. Could there have been some corruption problem with the main registry, perhaps?

actually, I still get the error in Travis:

What I had in mind was that you might be calling a CSV function in the tests without `using CSV` in `runtests.jl`, but that doesn’t seem to be the problem.

Then I’m afraid it’s hard to figure out the problem without a MWE.

Maybe, the same solution works here: [CSV Parsers dependency problem](https://discourse.julialang.org/t/csv-parsers-dependency-problem/23827)

> [@CSV Parsers dependency problem](https://discourse.julialang.org/t/csv-parsers-dependency-problem/23827/2):
>
> I think the issue is that the previous CSV.jl release probably has a dependency version like “Parsers \>= 0.2” or something, and then when Parsers.jl made a breaking release to `0.3.0` , it breaks CSV.jl. I think if you do something like `] pin Parsers 0.2.22` , it should fix it for now.

It might be easier than that: if you don’t have a separate environment for the tests, include all the packages used in `runtests.jl` in the corresponding target of the package’s `Project.toml`, for instance:

```nohighlight
[targets]
test = ["Test", "CSV", "MoltenSaltThermodynamics"]

```

Thanks everyone for the help! In the end I was able to solve the problem by creating a specific environment for testing as described in the link that @hendri54 posted. That seems to be the best way of going about this. I didn’t know that Julia had added that capability, but it shows me that I should read the Pkg documentation more carefully!
