Running PlenaryBustedDirectory with more than one option via the command interface

[williamboman]

The docs suggest that one can run a test suite through the PlenaryBustedDirectory command. This seems to take two arguments - the second one being a Lua table of options. I learned that you can only really provide one entry in this table, as doing anything else seem to induce ambiguous syntax and the argument gets translated to something completely else.

For example, the following:

$ nvim --headless -c "PlenaryBustedDirectory tests/plenary/ {minimal_init = '/foobar', sequential=true}"

will make the test harness receive it as:

  local split_string = vim.split(command, " ")
  local directory = table.remove(split_string, 1) 

  print(vim.inspect(split_string)) -- { "minimal_init='/foobar'\n.", "", "sequential=true" }

  local opts = assert(loadstring("return " .. table.concat(split_string, " ")))()

  return harness.test_directory(directory, opts)

I've not researched this much more than this, but it seems like the comma might be the culprit.

To resolve this, I bypassed the command interface and call the Lua API directly instead, like so:

$ nvim --headless -c "lua require('plenary.test_harness').test_directory('.', {minimal_init='/foobar',sequential=true})"

I wonder if the docs should be updated to reflect this, and perhaps even deprecate this particular command interface?
