Show HN: Testbox – A fast test runner with zero dependencies

A fast test runner that works out of the box. Zero dependencies.

- Tests are written in Lua (but you don't need Lua installed on your system)

- Batteries included for API testing

$ testbox - <<EOF

test("just a test", function()

expect_equal(2, 1 + 1)

end)

test("this will fail!", function()

expect_equal(1, 2)

end)

EOF

# Prints out:

✅ just a test

❌ this will fail!

Not equal!

Left: 1

Right: 2If you have cargo/rust on your system:

$ cargo install testbox

...

$ testbox --versionOtherwise you can just download the compiled executable from the releases page.

$ testbox - <<EOF

test("API test: get users", function()

exec_bg("cd path/to/my/app ; npm run dev", {

wait = function(stdout, stderr)

return string.match(stdout, "Server is ready") ~= nil

end

})

local response = fetch({

url = "http://localhost:3000/api/users",

method = "GET",

})

expect_equal(response.json.users[1].email, "someuser@example.com")

end)

EOFtestbox - <<EOF

test("uppercase text with awk", function()

expect_equal(

exec([[echo foobar | awk '{print toupper($0)}']]).output,

"FOOBAR",

)

end)

EOFThe examples above use helper functions such as exec_bg and fetch. These functions are part of the Testbox Library, which you can learn more about here.
