lua-resty-busted

A little hack to test OpenResty scripts with busted.

By overriding the busted executable with the one shipped with this module, busted runs with the resty-cli interpreter, which can execute Lua scripts written for OpenResty from the CLI.

Install

By default, the script is installed under /usr/local/bin. You can use the Makefile variables (also from Luarocks) to install it somewhere else.

Luarocks:

$ luarocks install lua-resty-busted

Makefile:

$ make install

Manually: just copy the bin/busted script somewhere in your $PATH.

Usage

describe("openresty script", function()
  it("should run in ngx_lua context", function()
    assert.equal(0, ngx.OK)
    assert.equal(200, ngx.HTTP_OK)
  end)
  it("should wait", function()
    ngx.sleep(3)
    assert.is_true(1 == 1)
  end)
end)

From resty-cli's documentation:

The Lua code is initiated by the init_worker_by_lua directive and run in the context of ngx.timer callback. So all of ngx_lua's Lua APIs available in the ngx.timer callback context are also available in the resty utility. We may remove some of the remaining limitations in the future though.
