 ## Methods
 
 To stay minimal, `test.it` only has 3 core functions:
 - `it` to capture your tests
 - `run` to execute yours tests
-- and `expects` to write your assertions
+- and `assert` to write your assertions
 
-While you can use your own assertion library, the included `expects` provides the following methods for writing your tests:

-| `.expects(tests).to.exist()`      | truthy evalution `.exist` or `.be.ok()` |
-| `.expects().to.pass()`            | pass test                               |
-| `.expects().to.fail(message)`     | fails test with message                 |
-| `.expects(this).to.equal(that)`   | strictly equal evaluation using `===`   |
-| `.expects(this).to.be.like(that)` | loose evaluation using `==`             |
-| `.expects(123).to.be.a('number')` | check typeof value (`.a()` or `.an()`)  |

-> NOTE: wish `eval` was not so evil, `assert(expression, message)` would be ideal
 
 if you want to shorten test typing try
 
-    let expect = test.expects;
+    let assert = test.assert;
 
 putting that above your tests will allow you to write like
