Chemistry

A testing framework for Elixir.

Installation

available in Hex, the package can be installed as:

1. Add chemistry to your list of dependencies in mix.exs:

def deps do
  [{:chemistry, "~> 0.1.4"}]
end

1. Ensure chemistry is started before your application:

def application do
  [applications: [:chemistry]]
end

Examples

From Interactive Elixir, type iex from terminal.

iex(1)> import Chemistry.Lab 
Chemistry.Lab
iex(2)> expect 1 == 1
.:ok
iex(3)> expect 1 > 1
FAILURE:
  Expected: 1 to be greater than 1

:ok
iex(4)> 

Place all labs inside of ./lab and be sure to append _lab.exs to anything you want to be a lab.

Write expressive tests using a call to it followed by a description for the lab.

defmodule MathLab do
  use Chemistry.Lab

  it "Can use integers for addition and subtraction." do
    expect 2 + 3 == 5
    expect 5 - 5 == 10
  end

  it "Can use integers for multiplication and division" do
    expect 5 * 5 == 25
    expect 10 / 2 == 5
  end
end

Run iex from the terminal to see an example file message.

iex(1)> MathLab.run
.===========================================
FAILURE: Can use integers for addition and subtraction.
===========================================
FAILURE:
  Expected: 0 to be equal to 10
