 `React.addons` is where we park some useful utilities for building React apps. **These should be considered experimental** but will eventually be rolled into core or a blessed utilities library:
 
-- `ReactTransitions`, for dealing with animations and transitions that are usually not simple to implement, such as before a component's removal.
-- `ReactLink`, to simplify the coordination between user's form input data and and the component's state.
-- `classSet`, for manipulating the DOM `class` string a bit more cleanly.
+- [`ReactTransitions`](animation.html), for dealing with animations and transitions that are usually not simple to implement, such as before a component's removal.
+- [`ReactLink`](two-way-binding-helpers.html), to simplify the coordination between user's form input data and and the component's state.
+- [`classSet`](class-name-manipulation.html), for manipulating the DOM `class` string a bit more cleanly.
+- [`ReactTestUtils`](test-utils.html), simple helpers for writing test cases (unminified build only).
 
 To get the add-ons, use `react-with-addons.js` (and its minified counterpart) rather than the common `react.js`.

 `classSet()` is a neat utility for easily manipulating the DOM `class` string.

+`React.addons.TestUtils` makes it easy to test React components in the testing framework of your choice (we use [Jasmine](http://pivotal.github.io/jasmine/) with [jsdom](https://github.com/tmpvar/jsdom)).
+
+#### ReactComponent renderIntoDocument(ReactComponent instance)
+
+Render a component into a detached DOM node in the document. **This function requires a DOM.**
+
+#### boolean isComponentOfType(ReactComponent instance, function componentClass)
+
+Returns true if `instance` is an instance of a React `componentClass`.
+
+#### boolean isDOMComponent(ReactComponent instance)
+
+Returns true if `instance` is a DOM component (such as a `<div>` or `<span>`).
+
+#### boolean isCompositeComponent(ReactComponent instance)`
+
+Returns true if `instance` is a composite component (created with `React.createClass()`)
+
+#### boolean isCompositeComponentWithType(ReactComponent instance, function componentClass)
+
+The combination of `isComponentOfType()` and `isCompositeComponent()`.
+
+#### boolean isTextComponent(ReactComponent instance)
+
+Returns true if `instance` is a plain text component.
+
+#### array findAllInRenderedTree(ReactComponent tree, function test)
+
+Traverse all components in `tree` and accumulate all components where `test(component)` is true. This is not that useful on its own, but it's used as a primitive for other test utils.
+
+#### array scryRenderedDOMComponentsWithClass(ReactCompoennt tree, string className)
+
+Finds all instance of components in the rendered tree that are DOM components with the class name matching `className`.
+
+#### ReactComponent findRenderedDOMComponentWithClass(ReactComponent tree, string className)
+
+Like `scryRenderedDOMComponentsWithClass()` but expects there to be one result, and returns that one result, or throws exception if there is any other number of matches besides one.
+
+#### array scryRenderedDOMComponentsWithTag(ReactComponent tree, string tagName)
+
+Finds all instance of components in the rendered tree that are DOM components with the tag name matching `tagName`.
+
+#### ReactComponent findRenderedDOMComponentWithTag(ReactComponent tree, string tagName)
+
+Like `scryRenderedDOMComponentsWithTag()` but expects there to be one result, and returns that one result, or throws exception if there is any other number of matches besides one.
+
+#### array scryRenderedComponentsWithType(ReactComponent tree, function componentClass)
+
+Finds all instances of components with type equal to `componentClass`.
+
+#### ReactComponent findRenderedComponentWithType(ReactComponent tree, function componentClass)
+
+Same as `scryRenderedComponentsWithType()` but expects there to be one result and returns that one result, or throws exception if there is any other number of matches besides one.
+
+#### object mockComponent(function componentClass, string? tagName)
+
+Pass a mocked component module to this method to augment it with useful methods that allow it to be used as a dummy React component. Instead of rendering as usual, the component will become a simple `<div>` (or other tag if `mockTagName` is provided) containing any provided children.
+
+#### Simulate.{eventName}({ReactComponent|DOMElement} element, object nativeEventData)
+
+Simulate an event dispatch on a React component instance or browser DOM node with optional `nativeEventData` event data. **This is possibly the single most useful utility in `ReactTestUtils`.**
+
+> Note:
+>
+> This helper is used to simulate browser events, so synthetic React events like `change` are not available. If you want to test `change`, simulate the underlying `input` browser event.
+
+Example usage: `React.addons.TestUtils.Simulate.click(myComponent)`
+
+`Simulate` has a method for every event that React understands.
