## ExSpec
[![Build Status](https://travis-ci.org/drewolson/ex_spec.svg)](https://travis-ci.org/drewolson/ex_spec) [![Hex Version](http://img.shields.io/hexpm/v/ex_spec.svg?style=flat)](https://hex.pm/packages/ex_spec) [![Hex docs](http://img.shields.io/badge/hex.pm-docs-green.svg?style=flat)](https://hexdocs.pm/ex_spec)
ExSpec is a simple wrapper around ExUnit that adds Rspec-style macros. Specifically, it adds `context` and `it`.
While it takes inspiration from Rspec, ExSpec is significantly simplier. The `context` macro has only two functions:
1. Aid test organization
2. Prepend to the message of any `it` defined within its do blocks
The `it` macro is identical to `ExUnit.Case.test` except that it is aware of the messages of its surrounding `context` blocks. It also works seemlessly with `ExUnit`'s `describe` function.
Other than the functionality described above, ExSpec is just ExUnit. When `use`ing `ExSpec`, any options provided will be passed to `ExUnit.Case` (e.g. `async: true`).
A simple example is shown below. For more examples, see the tests.
### Example
```elixir
defmodule PersonTest do
use ExSpec, async: true
describe "name" do
context "with first and last name" do
it "joins the names with a space" do
drew = %Person{first_name: "Drew", last_name: "Olson"}
assert Person.name(drew) == "Drew Olson"
end
end
context "with only a first name" do
it "returns the first name" do
drew = %Person{first_name: "Drew", last_name: nil}
assert Person.name(drew) == "Drew"
end
end
end
end
```
### Installation
Add `ex_spec` to your `mix.exs` dependencies:
```elixir
def deps do
[{:ex_spec, "~> 2.0", only: :test}]
end
```
