Steps to reproduce
/**
* @jest-environment jsdom
*/
describe('test', () => {
it('test', () => {
const obj = {}
Object.defineProperty(obj, 'tt', {
writable: false,
value: 1,
configurable: true
})
expect(obj.tt).toBe(1)
Object.defineProperty(obj, 'tt', {
writable: false,
value: 2,
configurable: true
})
expect(obj.tt).toBe(2)
})
it('jsdom', () => {
Object.defineProperty(window, 'tt', {
writable: false,
value: 1,
configurable: true
})
expect(window.tt).toBe(1)
Object.defineProperty(window, 'tt', {
writable: false,
value: 2,
configurable: true
})
expect(window.tt).toBe(2)
})
})Expected behavior
expect consistent behavior of defineProperty on window
Actual behavior
jsdom test case not pass
Additional context
I thought it was a jsdom problem, but I only used jsdom for testing and the result was ok
const jsdom = require('jsdom')
const { JSDOM } = jsdom
const dom = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`)
Object.defineProperty(dom.window, 'JSB', {
writable: false,
value: undefined,
configurable: true
})
console.log(dom.window.JSB) // undefined
Object.defineProperty(dom.window, 'JSB', {
writable: false,
value: 1,
configurable: true
})
console.log(dom.window.JSB) // 1Environment
