我有這樣的測試:簡單測試,但無效定位:-(
// import {by, element, browser} from "protractor";
describe('intro',() => {
beforeEach(() => {
browser.get('');
});
it('should have multiple pages',() => {
let buttonOnward = element(by.linkText('Continue'));
expect(element.all(buttonOnward).count()).toBe(1);
});
});
而得到這樣的結果
1) intro should have multiple pages

而且我不知道爲什麼它很簡單,我下載了。茉莉和分型檢查該文件C:\Users\Patrick\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\lib\by.js
沒有爲它定義一個函數:
而且文檔說該函數也存在。
