Test the Elixir code in your markdown!
## Usage
Add `:markdown_test` as a dependency in your `mix.exs` file:
```elixir
# mix.exs
defp deps do
[
{:markdown_test, "0.1.2", only: :test}
]
end
```
In any test module, `use MarkdownTest` to pull in the `test_markdown/1` macro and call it for your markdown file:
```elixir
defmodule MyLibraryTest do
use MarkdownTest
test_markdown("README.md")
end
```
Then add some Elixir code to test in your markdown file.
The format roughly resembles that of a [`doctest`](https://elixir-lang.org/getting-started/mix-otp/docs-tests-and-with.html).
In order to be picked up, a code block must be between the following markdown comment tags:
``
...code
``.
### Examples
```elixir
iex> 1 + 2
3
```
The expression and expected values can span multiple lines:
```elixir
iex> a = %{cool: :beans}
...> b = %{beans: :cool}
...> Map.merge(a, b)
%{
cool: :beans,
beans: :cool
}
```
You can also include any setup code that needs to be run prior to testing the code:
```elixir
defmodule MyModule do
def add(x, y), do: x + y
end
iex> MyModule.add(1, 2)
3
```
`markdown_test` will assert that the expression and the expected value match according to [Elixir's pattern matching](https://elixir-lang.org/getting-started/pattern-matching.html).
Therefore, you can write a test like this:
```elixir
defmodule MyModule do
def big_result do
{:ok, List.duplicate("hey", 1000)}
end
end
iex> MyModule.big_result()
{:ok, ["hey" | _]}
```
If you don't add any assertion code, `markdown_test` will just verify that the code snippet compiles, like:
```elixir
%{
this: %{
"should" => :compile
}
}
```
