I’m still relatively new to this myself, but looking at the documentation, I thought the use of test/Project.toml was for setting the dependencies for Julia 1.2, and the [targets] lines in the project’s Project.toml were for Julia 1.0?
I followed the Julia 1.2 instructions for my project, and there are no [targets] in my project Project.toml. The test/Project.toml was generated like you showed in your original post.
