chai-react is an extension to the chai assertion library that provides a set of React-specific assertions.
Although chai-react is still a great tool for making assertions on components
themselves, it started getting a little bloated by trying to solve two problems
at once: React tree traversal and tree assertions.
A new library called rquery makes a better
attempt at focusing on React tree traversal, and leaving assertions to chai-react.
It provides an interface similar to jQuery for traversing rendered React trees. Use
rquery to traverse your component's tree, and then chai-react to make assertions
on that traversal.
Example:
var $component = $R(component);
expect($component.find('MyComponent')[0]).to.have.prop('something');
expect($component.find('div')[0]).to.have.prop('id', 'abc');
// simulate events
expect($component.find('.save-notice')).to.have.length(0);
$component.find('button.save').click();
expect($component.find('.save-notice')).to.have.length(1);
To run the test suite, run npm install (requires
Node.js to be installed on your system), and open
test/index.html in your web browser.
