Additional context
treesitter parser not found but I have installed javascript and I have reinstalled all the plugins, but still the same no tests found

apparently you have to use the nvim-treesitter dependency

  {
    "nvim-neotest/neotest",
    event = "LspAttach",
    dependencies = {
      "nvim-treesitter/nvim-treesitter", -- this adding nvim-treesitter
      "haydenmeade/neotest-jest",
      "marilari88/neotest-vitest",
      "nvim-neotest/neotest-go",
    },
    config = function()
      require "custom.configs.neotest"
    end,
    init = function(_)
      require("core.utils").load_mappings "neotest"
    end,
  },

Loading treesitter on VeryLazy can break neotest

In PR #298 the following line was removed from neotest.lib.subprocess:

nio.fn.rpcrequest(child_chan, "nvim_exec_lua", "require('nvim-treesitter')", {})

As a consequence, neotest can break for users of lazy.nvim, when loading nvim-treesitter on VeryLazy(scheduled on UIEnter).
Neotest runs tests in a new Neovim instance, expecting plugins to be ready on VimEnter.
Thus, in that instance, nvim-treesitter is loaded too late.

For LazyVim, @folke fixed the problem in v10.6.0

Note: For python, in Neovim nightly, the tests run fine, because nightly ships with parsers and queries for Markdown, Python, and Bash.

Steps on linux:
1. create dir ~/.config/repro
2. add this file as ~/.config/repro/init.lua

fyi: this is not just with lazy.nvim. Any kind of lazy loading of nvim-treesitter that happens after VimEnter will prevent tests working properly on stable.

It might be good to keep something like the below:

nio.fn.rpcrequest(child_chan, "nvim_exec_lua", "pcall(require, 'nvim-treesitter')", {})

Edit: to be fair, this would only help users that use lazy.nvim since lazy automatically loads a plugin when you require one of its modules...

Hint: neotest does not work (returns "No tests found") for me on nvim-treesitter@v0.9.2. It works when downgrading to v0.9.1: #348 (comment)

[rcarriga]

Sorry for the late reply to this, I've added back the call for nvim-treesitter in the subprocess on startup

[rcarriga]

Closing, feel free to re-open if it's not fixed

[fnune]

Updating neotest-jest has made things work for me with treesitter on v0.9.2: nvim-neotest/neotest-jest#100
