Set experimental fields dynamically

[drewbailey]

Is it possible to set experimental fields dynamically? I would like to make a keymap to run with test_table = true, but keep it set to false by default.

Unfortunately I've been unable to configrue neotest/neotest-go to work properly with this setup.

return {
  "nvim-neotest/neotest",
  dependencies = {
    "nvim-neotest/nvim-nio",
    "nvim-neotest/neotest-go",
    "nvim-lua/plenary.nvim",
    "antoinemadec/FixCursorHold.nvim",
    "nvim-treesitter/nvim-treesitter",
  },
  opts = {},
  config = function(_, opts)
    local neotest = require("neotest")
    local neotest_go = require("neotest-go")

    -- Default adapter configuration
    local adapter = neotest_go({
      experimental = {
        test_table = false, -- Default behavior
      },
      args = { "-count=1", "-timeout=30s" },
    })

    opts.adapters = { adapter }
    neotest.setup(opts)

    -- Function to run with `test_table` enabled
    local function run_with_test_table()
      -- Print debug messages
      print("Running with `test_table` enabled")

      -- Update the adapter dynamically
      local temp_adapter = neotest_go({
        experimental = {
          test_table = true,
        },
        args = { "-count=1", "-timeout=30s" },
      })

      -- Reconfigure Neotest with the temporary adapter
      neotest.setup({
        adapters = { temp_adapter },
      })

      -- Run tests
      neotest.run.run(vim.fn.expand("%")) -- Run tests in the current file

      -- Restore the default adapter
      neotest.setup({
        adapters = { adapter },
      })
    end

    -- Keymaps
    vim.keymap.set("n", "<leader>tf", function()
      require("neotest").run.run(vim.fn.expand("%"))
    end, { desc = "[t]est [f]ile" })

    vim.keymap.set("n", "<leader>T", function()
      require("neotest").run.run()
    end, { desc = "[t]est current function" })

    vim.keymap.set("n", "<leader>tS", function()
      require("neotest").run.stop()
    end, { desc = "[S]top" })

    vim.keymap.set("n", "<leader>tw", function()
      require("neotest").watch.toggle(vim.fn.expand("%"))
    end, { desc = "[t]oggle [w]atch" })

    vim.keymap.set("n", "<leader>tts", function()
      require("neotest").summary.toggle()
    end, { desc = "[t]oggle [t]est [s]ummary" })

    vim.keymap.set("n", "<leader>tto", function()
      require("neotest").output.open({ enter = true, auto_close = true })
    end, { desc = "[t]oggle [t]est [o]utput" })

    vim.keymap.set("n", "<leader>ttO", function()
      require("neotest").output_panel.toggle()
    end, { desc = "[t]oggle [t]est [O]utput panel" })

    -- Custom keymap for running with `test_table`
    vim.keymap.set("n", "<leader>ts", function()
      run_with_test_table()
    end, { desc = "Run [t]ests with [s]ingle table test" })
  end,
}
