Hey 👋

The rustaceanvim.neotest module definitely exists, so this is not a bug. It's an issue with how lazy.nvim loads plugins - I will convert this to a Q&A discussion.

I believe your issue is that you are calling require('rustaceanvim.neotest') when passing it to the opts table. So it gets called at lazy.nvim's plugin spec evaluation time (which is before it has loaded any plugins and I suppose before it overrides the require function to search for plugins to load).

You should be able to work around this either by changing it to

opts = function(_, opts)
  opts.adapters = opts.adapters or {}
  vim.list_extend(opts.adapters, {
    require('rustaceanvim.neotest'),
  })
end

Or replace opts with

config = function()
  require("neotest").setup({
    adapters = {
      require("rustaceanvim.neotest")
    }
  })
end

I chose the second approach and it works now. Thanks
