neotest-swift-testing

This is an adapter for using the neotest framework with Swift Testing.

The plugin is tested with Xcode 16 only but might work with earlier versions as well. Thanks to Emmet Murray for his neotest-swift plugin which I used as a starting point. I focused on Swift Testing only, legacy XCTest is not supported but might work.

Features

• - Run Swift Test suites and tests
• - Debug tests cases with neotest dap support
• - Show parametrized tests in the test list

Neovim DAP configuration for Swift

Add the following configuration file (e.q. neovim-dap.lua for Lazy) to enable debugging of Swift code with nvim-dap:

return {
    "mfussenegger/nvim-dap",
    optional = true,
    dependencies = "williamboman/mason.nvim",
    opts = function()
        local dap = require("dap")
        if not dap.adapters.lldb then
            local lldb_dap_path = vim.fn.trim(vim.fn.system("xcrun -f lldb-dap"))
            dap.adapters.lldb = {
                type = "executable",
                command = lldb_dap_path, -- adjust as needed, must be absolute path
                name = "lldb",
            }
        end

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