INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:

Idiomatic React Testing Patterns

Testing React components seems simple at first. Then you need to test something that isn't a pure interaction and things seem to break down. These 4 patterns should help you write readable, flexible tests for the type of component you are testing.

Setup

I recommend doing all setup in the most functional way possible. If you can avoid it, don't set variables in a beforeEach. This will help ensure tests are isolated and make things a bit easier to reason about. I use a pattern that gives great defaults for each test example but allows every example to override props when needed:

package main
import (
	"./binding"
	"fmt"
)

func main() {
	binding.PrintHello()
	binding.Seed(1)
	fmt.Println(binding.Random())

An Example of Play

To further clarify what really goes on during an AD&D game, read the following example. This is typical of the sort of action that occurs during a playing session. Shortly before this example begins, three player characters fought a skirmish with a wererat (a creature similar to a werewolf but which becomes an enormous rat instead of a wolf). The wererat was wounded and fled down a tunnel. The characters are in pursuit. The group includes two fighters and a cleric.

Fighter 1 is the group's leader.
