Quicktest

• Contextual Test Triggering: Run tests directly from where your cursor is located or execute all tests in the entire file/dir/project.
• Flexible Test Reruns: Rerun tests from any location(with require('quicktest').run_previous(), keybind is in usage example), automatically opening window or using an existing if it's open.
• Live-Scrolling Results: Continuously scroll through test results as they are generated. But stop scrolling if you decided to scroll up.
• Real-Time Feedback: View the results of tests immediately as they run, without waiting for the completion of the test suite.
• Test Duration Timer: Display a timer to monitor the duration of ongoing tests.
• ANSI colors EXPERIMETAL
• Easy to write your own adapter: It's just all about running cmd and piping results to quicktest.

Languages with multiple adapters

Same languages like Javascript/Typescript support multiple adapters that might match the same test file. Use the is_enabled option to control which adapter should be used for the current buffer.

Some adapters like playwright and vitest provide a helper function to determine whether the current buffer imports from a certain package like @playwright or vitest. Here is a sample configuration for a project with Playwright and vitest tests:

local qt = require("quicktest")
local playwright = require("quicktest.adapters.playwright")
local vitest = require("quicktest.adapters.vitest")

qt.setup({
  adapters = {
    vitest({
      is_enabled = function(bufnr)
        return vitest.imports_from_vitest(bufnr)
      end
    }),
    playwright({
      is_enabled = function(bufnr)
        -- In case you are not using the default `@playwright` package but your own
        -- wrapper, you can specify the package-name that has to be imported
        return playwright.imports_from_playwright(bufnr, "my-custom-playwright")
      end
    }),
  },
})

Building your own adapter

Here is the template of how adapter for any language could be written. For more examples just check lua/quicktest/adapters. For tresitter methods investigation you can take code from adapters of neotest from https://github.com/nvim-neotest/neotest?tab=readme-ov-file#supported-runners

local Job = require("plenary.job")

local M = {
  name = "myadapter",
}

---@field func_names string[]
---@field bufnr integer
---@field cursor_pos integer[]

--- Optional:
