I am trying to mock the window.navigator.language
attribute in the browser in my jest unit tests so I can test that the content on my page is using the correct language
I have found people online using this:
Object.defineProperty(window.navigator, 'language', {value: 'es', configurable: true});
I have set it right at the top of my test file and it is working there
however, when I redefine in an individual test (and people set to make sure configurable was set to true) it wont redefine it and is just using the old value, does anyone know a way to definitely change it?
beforeEach(() => {
jest.clearAllMocks()
Object.defineProperty(global.navigator, 'language', {value: 'es', configurable: true});
wrapper = shallow(<Component {...props} />)
})
it('should do thing 1', () => {
Object.defineProperty(window.navigator, 'language', {value: 'de', configurable: true});
expect(wrapper.state('currentLanguage')).toEqual('de')
})
it('should do thing 2', () => {
Object.defineProperty(window.navigator, 'language', {value: 'pt', configurable: true});
expect(wrapper.state('currentLanguage')).toEqual('pt')
})
for these tests it is not changing the language to the new language I have set, always using the one at the top
