`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)
|
||||
### Simulate
|
||||
|
||||
```javascript
|
||||
Simulate.{eventName}({ReactComponent|DOMElement} element, object eventData)
|
||||
```
|
||||
|
||||
Simulate an event dispatch on a React component instance or browser DOM node with optional `eventData` event data. **This is possibly the single most useful utility in `ReactTestUtils`.**
|
||||
|
||||
Example usage:
|
||||
|
||||
```javascript
|
||||
React.addons.TestUtils.Simulate.click(myComponent);
|
||||
React.addons.TestUtils.Simulate.change(myComponent);
|
||||
React.addons.TestUtils.Simulate.keydown(myComponent, {key: "Enter"});
|
||||
```
|
||||
|
||||
`Simulate` has a method for every event that React understands.
|
||||
|
||||
### renderIntoDocument
|
||||
|
||||
```javascript
|
||||
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)
|
||||
### mockComponent
|
||||
|
||||
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)
|
||||
```javascript
|
||||
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)
|
||||
### isComponentOfType
|
||||
|
||||
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`.**
|
||||
```javascript
|
||||
boolean isComponentOfType(ReactComponent instance, function componentClass)
|
||||
```
|
||||
|
||||
> 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.
|
||||
Returns true if `instance` is an instance of a React `componentClass`.
|
||||
|
||||
Example usage: `React.addons.TestUtils.Simulate.click(myComponent)`
|
||||
### isDOMComponent
|
||||
|
||||
`Simulate` has a method for every event that React understands.
|
||||
```javascript
|
||||
boolean isDOMComponent(ReactComponent instance)
|
||||
```
|
||||
|
||||
Returns true if `instance` is a DOM component (such as a `<div>` or `<span>`).
|
||||
|
||||
### isCompositeComponent
|
||||
|
||||
```javascript
|
||||
boolean isCompositeComponent(ReactComponent instance)`
|
||||
```
|
||||
|
||||

|
||||
```
|
||||
|
||||
The combination of `isComponentOfType()` and `isCompositeComponent()`.
|
||||
|
||||
### isTextComponent

```javascript
|
||||
boolean isTextComponent(ReactComponent instance)
|
||||
```
|
||||
|
||||
Returns true if `instance` is a plain text component.
|
||||
