react-shallow-testutils
Replacement for TestUtils when using React's shallow rendering.
npm install react-shallow-testutils
React Versions
If you're using React 0.13 then stick to 0.4.0 as 0.5.0 and onwards will support React 0.14.
getMountedInstance
Returns the mounted component from a shallow renderer. This function will be on the shallow renderer itself in React 0.15 but I've included it in this module for now as it's so useful. It allows you to call instance functions like forceUpdate.
import ReactTestUtils from 'react-addons-test-utils';
import ShallowTestUtils from 'react-shallow-testutils';
const renderer = ReactTestUtils.createRenderer();
renderer.render(<MyComponent />, context);
const component = ShallowTestUtils.getMountedInstance(renderer);isComponentOfType
Returns whether a component instance is of a particular type.
boolean isComponentOfType(ReactComponent component, function componentClass)isDOMComponent
Returns whether the supplied component is a DOM component or not
boolean isDOMComponent(function component)findAll
Traverses the tree and returns all components that satisfy the function test.
array findAll(ReactComponent tree, function test)findAllWithType
Finds all instances of components in the tree with a type that matches
type. This is like both React's scryRenderedDOMComponentsWithTag and scryRenderedComponentsWithType as you can supply a component class or a DOM tag.
array findAllWithType(ReactComponent tree, function componentClass | string tagName)findWithType
Find only one instance of a components in the tree with a type that matches
type. This is like both React's findRenderedDOMComponentWithTag and findRenderedComponentWithType as you can supply a component class or a DOM tag.
ReactComponent findWithType(ReactComponent tree, function componentClass | string tagName)findAllWithClass
Finds all instances of components in the tree with a class that matches className. This is different to React's scryRenderedDOMComponentsWithClass in that it will check all components and not just DOM components.
array findAllWithClass(ReactComponent tree, string className)You can pass a className like test-class.test-class--modified to find a component that has both classes.
findWithClass
Find only one instance of a component in the tree with a class that matches className. This is different to React's findRenderedDOMComponentWithClass in that it will check all components and not just DOM components.
ReactComponent findWithClass(ReactComponent tree, string className)You can pass a className like test-class.test-class--modified to find a component that has both classes
findWithRef
Find only one instance of a component in the tree with a ref that matches ref.
ReactComponent findWithRef(ReactComponent tree, string ref)
