ReactTestUtils

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

//importing

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

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

Simulate has a method for every event that React understands.

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

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

renderIntoDocument(element)

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.

mockComponent(
  componentClass,
  [mockTagName]
)

Returns true if element is any React element.

isElement(element)

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

isElementOfType(
  element,
  componentClass
)

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

isDOMComponent(instance)

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

isCompositeComponent(instance)

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.

findAllInRenderedTree(
  tree,
  test
)

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

scryRenderedDOMComponentsWithClass(
  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.

findRenderedDOMComponentWithClass(
  tree,
  className
)

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

scryRenderedDOMComponentsWithTag(
  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.

findRenderedDOMComponentWithTag(
  tree,
  tagName
)

Finds all instances of components with type equal to componentClass.

scryRenderedComponentsWithType(
  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.

findRenderedComponentWithType(
  tree,
  componentClass
)
