ReactTestUtils

//importing

import ReactTestUtils from 'react-dom/test-utils'; // ES6
var ReactTestUtils = require('react-dom/test-utils'); // ES5

Makes it easy to test React components in the testing framework of your choice.

Simulate.{eventName}(
  element,
  [eventData]
)

Simulate an event dispatch on a DOM node with optional eventData event data.

Simulate has a method for every event that React understands.

renderIntoDocument(element)

Render a React element into a detached DOM node in the document (this function requires a DOM).

mockComponent(
  componentClass,
  [mockTagName]
)

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.

isElement(element)

Returns true if element is any React element.

isElementOfType(
  element,
  componentClass
)

Returns true if element is a React element whose type is of a React componentClass.

isDOMComponent(instance)

Returns true if instance is a DOM component (such as a <div> or <span>).

isCompositeComponent(instance)

Returns true if instance is a user-defined component, such as a class or a function.

findAllInRenderedTree(
  tree,
  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.

scryRenderedDOMComponentsWithClass(
  tree,
  className
)

Finds all DOM elements of components in the rendered tree that are DOM components with the class name matching className.

findRenderedDOMComponentWithClass(
  tree,
  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.

scryRenderedDOMComponentsWithTag(
  tree,
  tagName
)

Finds all DOM elements of components in the rendered tree that are DOM components with the tag name matching tagName.

findRenderedDOMComponentWithTag(
  tree,
  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.

scryRenderedComponentsWithType(
  tree,
  componentClass
)

Finds all instances of components with type equal to componentClass.

findRenderedComponentWithType(
  tree,
  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.
