electron - Cypress : Electron 不支持.finally()吗？

Question

Electron 3.x添加了对javascript .finally()的支持

我有一个问题，因为我的Vue应用在处理axios请求时实际上正在使用.finally。

由于.finally()，使用 Electron 进行的柏树测试失败。 ...

I cannot ask the team to refactor code for a problem only with a test suite and only with the 'auto' mode because we're still working on local culture to accept to spend time across testing. If I ask this to the devs, someone will shutdown testing...

问题: 是否有办法使Electron能够消化此语法？

该webapp由Laravel 5.8.x，Vue 2和axios组成，并通过webmix(webpack链)进行编译。

您有两种选择:

可以将cypress升级到3.5.0，即uses Electron5。

或使用polyfill。

首先，安装es-shims/Promise.prototype.finally:

npm install -D promise.prototype.finally

然后，在您的cypress/support/index.js中:

const { implementation: FinallyPolyfill } = require('promise.prototype.finally');

function loadPolyfill ( win ) {
    win.Promise.prototype.finally = FinallyPolyfill;
}

// polyfill AUT's Promise
Cypress.on('window:before:load', win => {
    loadPolyfill(win);
});

// polyfill Cypress runner's wrapper window Promise
before(() => {
    loadPolyfill(window);
});
