Fortran fpm Run Tests on Module in Parent Directory

Question

I have written a module in fortran that I want to test using fortran-fpm and vegetables.

My directory structure looks like this:

my_repo/
├─ foo/
│  ├─ bar/
│  │  ├─ my_module.f90
│  │  ├─ test/
│  │  │  ├─ main.f90
│  │  │  ├─ my_module_test.f90
├─ fpm.toml

When I run fpm test, I get this error:

<ERROR>*cmd_run*:targets error:Unable to find source for module dependency: "my_module" used by "foo/bar/test/my_module_test.f90"
STOP 1

If I instead move my_module.f90 into the test directory, all the tests run fine. How do I point my_module_test.f90 to my_module.f90 without having my source code in the test directory?

I have tried:

1. Including:

[test-dependencies]
my_module = { path = "foo/bar/my_module.f90" }

in my fpm.toml file at the top of my repo as suggested in the documentation. It then prompts me to put another fpm.toml file at foo/bar/. When I do that, it still gives me the same error.

2. Using putting file: "foo/bar/my_module.f90 at the top of my_module_test.f90. As suggested here.

EDIT: Note that my fpm.toml file looks like this:

name = "My_Project"
author = "NolantheNerd"

[install]
library = true

[library]
source-dir = "foo/bar"
include-dir = "foo/bar"

[build]
external-modules = "foo/bar"
link = "foo/bar/my_module.f90"

[dev-dependencies]
vegetables = { git = "https://gitlab.com/everythingfunctional/vegetables.git", tag = "v7.2.2" }

[[test]]
name = "TestsForMyModule"
source-dir = "foo/bar/test"
main = "main.f90"
link = "foo/bar/my_module.f90"

Many thanks to everythingfunctional, the creator of vegetables for his solution:

Your build section is incorrect, and actually unnecessary in your case. Try removing it and let us know how it goes.

Edit: just noticed as well that the link entry in your test section is incorrect and unnecessary as well.
