Hey everyone. I know that this topic has been covered many times, but nothing has worked for me. I am trying to create function that will shallow render my component with its store (Redux store). I am using this snippet:
export function shallowWithStore(component, store) {
function ProviderWrapper({ children }) {
return (
<Provider store={store}>
{children}
</Provider>
);
}
return shallow(component, {
wrappingComponent: ProviderWrapper,
});
}Later in the test I will use:
const component = shallowWithStore(<ReplyEditContainer />, createMockStore(store));And it seems it doesn't work. I always get the same error, even if I don't use wrappingComponent option at all.
Error: Could not find "store" in the context of "Connect(ReplyEditContainer)". Either wrap the root component in a <Provider>, or pass ...Is there anything missing in my code, because the API seems to fit perfectly for my usecase
mount with MobX observer component.it's throwing below error.

Hi, I am new to enzyme.
I am trying to test my functional component, but shallow returns me always null. Any idea where I should look at?
const wrapper = shallow(<MyComponent />);I do have set adapter in setupTest.js (app created with create-react-app)
import '@testing-library/jest-dom/extend-expect';
import { configure } from "enzyme";
import Adapter from "enzyme-adapter-react-16";
configure({ adapter: new Adapter() });I have tried to shallow on direct html element and this works fine.
const wrapper = shallow(<div >test</div>);For check I use
console.log(wrapper.first().html())

this.setState
class MyComp extends React.Component {
state = { value: '' }
handleChange = (e) => {
this.setState({ value: e.target.value }, () => {
// do sommething else
});
}
render() {
return (
<input onChange={ this.handleChange } />
)
}
}
const wrapper = shallow(<MyComp />);
wrapper.find('input').simulate('change', {
target: {
value: 1,
name: 0
}
});
expect(wrapper.state().value).toEqual('1'); // this gives error as it is receiving state.value as ''setState is not working?
this.setState shouldn't be given an object, it should be given a callback
handleChange =, instead of a proper bound prototype method, that means you also can't mock it out
I am using
mount to load a component into the DOM. One of its children is a Blueprint3.Select component whose value I want to change.Unlike with
shallow, I cannot use simulate on the react component to change its value which is wrapped in a <div>.I have two questions:
- Is there a way I can manipulate the DOM directly to set the value of the
<div>of this component? - Can we use
simulateon React component when usingmount?

Enzyme Internal Error: Enzyme expects an adapter to be configured, but found none.Is there anyone who could get in touch with me, we seem to have exhausted all the references and SO related links and we just can not get it to work. Please :(
Hey there. I'm facing an interesting problem that I can't figure out:
I got a form which I'm testing, so I get the submit button like this: button = wrapper.find('#notification-channel-add-button')
I then try so simulate a change event: input.simulate('change', { target: { value: 'Sample text' } })
Then, depending on how I test the disabled state of the button, I get different results:
// Correctly passes
expect(button.getDOMNode().hasAttribute('disabled')).toBeFalsy();
// This fails
expect(button.props().disabled).toBeFalsy();Has anyone ever faced this problem?
