Is it ever possible that packages will be downgraded when `Pkg.add`ing a package with no dependencies except `Test`?

```
julia> Pkg.add("some_package")

```

 ![a](https://global.discourse-cdn.com/julialang/original/3X/f/6/f6ff4bda4ae63a944a8f29e5865805f5721b8c51.png)

The `Project.toml` for the added package contains:

```
[deps]

[compat]
julia = "1"

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

[targets]
test = ["Test"]

```

Can we conclude that `Test` is responsible or **something else going on?**

If I dig one level down, this is the `Project.toml` for `Test.jl`, which doesn’t look like it would cause the downgrade shown in the screenshot?

```
name = "Test"
uuid = "8dfed614-e22c-5e08-85e1-65c5234f0b40"

[deps]
InteractiveUtils = "b77e0a4c-d291-57a0-90e8-8db25a27a240"
Logging = "56ddb016-857b-54e1-b83d-db4d58db5568"
Random = "9a3f8284-a2c9-5f02-9a11-845980a1fd5c"
Serialization = "9e88b42a-f829-5b0c-bbe9-9e923198166b"

```

Thanks.
