Example

Create a Makefile with the contents:

nvim-test:
	git clone https://github.com/lewis6991/nvim-test
	nvim-test/bin/nvim-test --init

.PHONY: test
test: nvim-test
	nvim-test/bin/nvim-test test \
		--lpath=$(PWD)/lua/?.lua

Add a test file test/mytest_spec.lua with the format:

local helpers = require('nvim-test.helpers')
local exec_lua = helpers.exec_lua
local eq = helpers.eq

describe('my tests', function()
  before_each(function()
    helpers.clear()

    -- Make plugin available
    exec_lua('package.path = ...', package.path)
  end)

  it('run a test', function()
    eq(true, exec_lua[[
        return require('myplugin').foo()
    ]])
  end)
end)

Then to run tests:

make test

nvim-test/bin/nvim-test test \
        --lpath=.../nvim-test/example/lua/?.lua
-------- Global test environment setup.

-------- 1 test from test/mytest_spec.lua (11.97 ms total)

-------- Global test environment teardown.
======== 1 test from 1 test file ran. (12.13 ms total)
PASSED   1 test.
