How to enable diagnostic messages?

[mrjones2014]

The help under :h neotest.diagnostic isn't very clear. vim.diagnostic.config() expects a number for the namespace parameter, but the help text for neotest says to use the string 'neotest'.

You can get the namespace number using nvim_create_namespace("neotest") and provide that to vim.diagnostic.config()
