How to override global object 'document' in jest junit test?
I want to test this class
export class FancyStuff extends React.Component<Props> {
componentWillMount() {
this.customBody = this.props.customBody || document.body;
...
As you can see, if I do not specify the property customBody, the component will try to get hold of the body of a document.
However for testing purpose, I need to ensure the document.body is a mock. At this stage I do not have the option to refactor the code to dependency inject the document object.
Is there anyway I can override this document.body globally in my unit test?
I tried something like document = mockWindow.document; before mounting the FancyStuff:
beforeEach(() => {
const mockWindow = {
document: {
body: {
appendChild: jest.fn(),
insertBefore: jest.fn(),
iamabody: jest.fn(),
},
}
jest.spyOn(window, 'open').mockReturnValue(mockWindow);
it('test fancystuff', () => {
document = mockWindow.document; // What I tried
mount((
<FancyStuffContainer/> // it uses FancyStuff
))
but I am not able to override document.body.
How can I do it in jest?
I am using the following versions:
"jest": "^23.2.0",
"jest-junit": "^5.1.0",
typescript jestjs
