Introduction

Lua Test Environment

Currently, only test agent is implemented.

Usage

GO111MODULE=on go get github.com/joesonw/lte/cmd/ds-agent

ds-agent run --debug -d ./examples/http -c 10 -n 100 main.lua

other flags please see ds-agent run -h

see examples for more

How it works

let's take following as an exmaple

local http = require "http"

function run(id)
    local err, body, headers, status = http:get("http://localhost:10080")()
    assert(err == nil)
    assert(status == 200)
    counter:add(1)
end

Note

• For each concurrent running instance (controlled by flag --concurrency/-c), it will only run once. And then for each request, only global function run is called.

• States are shared between runs for each instance, so please keep test related variables local inside run

• Async (network, file, sleep, etc) functions returns a Deferred, when you want to get the result, you can simply call the function to block.

  example:

  print(time:now())
  local a = sleep(1000000000)
  local b = sleep(1000000000)
  a()
  b()
  print(time:now()) -- only 1 second is passed
  

API

Global

group(name, function)

group("login related", function ()
    -- do login related test here
end)

sleep(ns)

local time = require "time"
print(time:now():string())
local block = sleep(1000000000) -- 1,000,000,000 nanoseconds = 1 second
block()
print(time:now():string())

import(file)

mylib.lua

local function echo(message)
    return "you said: " .. message
end

return echo

local echo = import "mylib.lua"
print(echo("hello"))

bytes

new(string, encoding?)

local bytes = require "bytes"
local s = bytes:new("hello")

__add, __concat, __eq

assert((bytes:new("hello") + bytes:new(" world")):string() == "hello world")
assert((bytes:new("hello") + " world"):string() == "hello world")
assert((bytes:new("hello") .. bytes:new(" world")):string() == "hello world")
assert((bytes:new("hello") .. " world"):string() == "hello world")
assert(bytes:new("hello") == bytes:new("hello"))

bytes:size()

assert(bytes:new("hello"):size() == 5)

bytes:string(encoding?)

assert(bytes:new("af", "hex"):string("hex") == "af")

bytes:replace(string)

assert(bytes:new("test"):replace("hello"):string() == "hello")

crypto

md5(content)

assert(crypto:md5("123456"):string() == "e10adc3949ba59abbe56e057f20f883e")

sha1(content)

sha256(content)

sha512(content)

sha3_224(content)

sha3_256(content)

sha3_384(content)

sha3_512(content)

FS

open(path)

local err, file = fs:open("/path")()

create(path)

local err, file = fs:create("/path")()

remove(path)

local err = fs:remove("/path")()

remove_all(path)

local err = fs:remove_all("/dir")()

list(path)

local err, stats = fs:list("/dir")()
print(stats[1].name)
print(stats[1].size)
print(stats[1].dir)
print(stats[1].modtime:string())

stat(path)

local err, stat = fs:stat("/file")()

mkdir_all(path)

local err = fs:mkdir_all("/some/deep/path")()

exist(path)

local err, ok = fs:exist("/some_file")()

read_all(path)

local err, contents = fs:read_all("/some_file")()

write(path, content)

local err = fs:write("/file", "hello world")()

file (from fs:open)

file:read(size)

local err, contents = file:read(5)() -- read 5 bytes

file:read_all()

local err, contents = file:read_all()()

file:write(content)

local err = file:write("hello world")()

file:close()

local err = file:close()()

file:name()

print(file:name())
