• Test watching
• Virtual text showing test failure messages
• Displaying full and short test output
• DAP support

Installation

packer.nvim

use {
  "nvim-neotest/neotest",
  requires = {
    "nvim-neotest/nvim-nio",
    "nvim-lua/plenary.nvim",
    "antoinemadec/FixCursorHold.nvim",
    "nvim-treesitter/nvim-treesitter",
    "ehmurray8/neotest-swift"
  }
}

Configuration

Neotest

Provide your adapters and other config to the setup function.

require("neotest").setup({
	adapters = {
		require("neotest-swift")({ }),
	},
    output = {
        enabled = true,
        open_on_run = false
    }
})

nvim-dap

Requires:

• nvim-dap
• codelldb
  • I installed it with Mason
• (Optional) nvim-dap-ui

local dap = require("dap")

local dapui = require("dapui")
dapui.setup()

-- Automatically attach and detach from DAPUI
dap.listeners.before.attach.dapui_config = function()
	dapui.open()
end
dap.listeners.before.launch.dapui_config = function()
	dapui.open()
end
dap.listeners.before.event_terminated.dapui_config = function()
	dapui.close()
end
dap.listeners.before.event_exited.dapui_config = function()
	dapui.close()
end

-- Use swift's LLDB
local libLLDB = "/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Versions/A/LLDB"

dap.adapters.swift = {
	type = "server",
	port = "${port}",
	executable = {
		command = "/Users/emmet/.local/share/nvim/mason/bin/codelldb", -- Use your exectuable I got this from Mason
		args = { "--liblldb", libLLDB, "--port", "${port}" },
	},
}

dap.configurations.swift = {
	{
		name = "Launch file",
		type = "swift",
		request = "launch",
		program = function()
			return vim.fn.input("Path to executable: ", vim.fn.getcwd() .. "/", "file")
		end,
		cwd = "${workspaceFolder}",
		stopOnEntry = false,
	},
}
