+# Test.it
+
+> A minimalistic testing library
+
+**Test.it** is a small testing library for people that want to live in code, not tests.  No over engineering here.  Inspired by the simplicity of libraries like [Tape](https://github.com/substack/tape), but the implementation ideas of [TinyTest](https://github.com/joewalnes/jstinytest)
+
+## Usage
+
+By default, you can run your tests like
+
+```js
+test.it({
+    'my passing test': function() {
+        test.pass();
+    },
+    'my failing test': function() {
+        test.fail('just wanted to fail fast');
+    }
+});
+```
+
+`test.it` will return `true` if the tests pass or `false` otherwise, in addition you should see the following console output
+
+```
++ my passing test
+- my failing test
+- - Error: just wanted to fail fast 
+    ...error stack...
+# tests 1 pass 1 fail 0
+```
+
+A `+` will proceed test lines that pass and a `-` for those that fail, the trace back `file:line` is included after the failing test proceeded by `- -`
+
+### Optional Next
+
+In addition to the default operation, `test.it` provides an optional `next` functional parameter that will return the results as an `object` for you to process *however* you like
+
+**For Fans of [TinyTest](https://github.com/joewalnes/jstinytest)**
+
+```js
+test.it({
+    'my passing test': function() {
+        test.pass();
+    }
+}, function(results) {
+    if (window.document && document.body) {
+        document.body.style.backgroundColor = (
+            results.fail.length ? '#ff9999' : '#99ff99'
+        );
+    }
+});
+```
+
+### Sample Results Object
+
+```json
+{
+    "pass": ['list of passed tests', ...],
+    "fail": ['list of errored tests', ...],
+}
+```
+
+From this you can easily find the number of tests ran `pass.length`, number of failed tests `fail.length` or the total test count by adding the two.  Simple.
+
+## Methods
+
+To stay minimal, `test.it` only provides 6 testing methods
+
+| Method                          | Description                   |
+| ------------------------------- | ----------------------------- |
+| `test.pass()`                   | pass test                     |
+| `test.fail(message)`            | fails test with message       |
+| `test.exists(value)`            | check if value exists         |
+| `test.assert(expected, actual)` | evaluates results using `==`  |
+| `test.equals(expected, actual)` | evaluates results using `===` |
+
+> NOTE: wish `eval` was not so evil, `assert(expression, message)` would be ideal
