Macro expect 

macro_rules! expect {
    ($value:expr) => { ... };

Example

use ferro_rs::expect;

expect!(actual).to_equal(expected);
expect!(result).to_be_ok();
expect!(vec).to_have_length(3);

Test: "returns all todos"
  at src/actions/todo_action.rs:25

  expect!(actual).to_equal(expected)

  Expected: 0
