我将Cypress从^ 3.1.0更新为^ 3.1.5，并且我有一组4个失败的测试。他们都做同样的事情。向主体元素发送转义，并声明关闭处理程序已触发。这是测试之一：
describe('Dialog', () => {
let closed;
const onClose = () => {
closed = true;
};
beforeEach(() => {
closed = false;
mount(
<Dialog open onClose={onClose}>
<div>Test</div>
</Dialog>
);
});
it('closes when clicking the backdrop', () => {
cy.get('[data-cy=dialog-backdrop]')
.click({force: true})
.then(() => {
cy.expect(closed).to.equal(true);
});
});
it('closes when pressing the escape key', () => {
cy.get('body')
.type('{esc}', {force: true})
.then(() => {
cy.expect(closed).to.equal(true);
});
});
});
第一个测试通过，第二个测试失败。唯一改变的是升级了jest，babel7和cypress。我还要寻找什么来解决这个问题？
