Question

我正在使用Azure DevOps在构建机器中运行我的Protractor测试用例。以前，所有代码都可以正常工作，但是突然在构建计算机上开始失败，根本没有任何提示。在E2E测试用例中调用browser.wait时，该测试用例失败。

我还验证了本地计算机浏览器和构建代理浏览器版本是否相同。该代码在我的本地计算机上执行，没有任何错误。

登录页面代码

login.po.ts：

login() {
browser.wait(ExpectedConditions.visibilityOf(element(by.id('xxx'))), 9000);
element(by.id('xxx')).sendKeys("test");
}

Run.spec.ts：

it block for Protractor where login code is called
    it("Should display title ", () => {
        loginpage.login();
});

我正在使用ng E2E运行代码。
本地和构建代理的纱线版本为1.15.2。
本地版本以及构建代理的节点版本为10.14.1。
Chrome版本73.0.3683.86

关于构建代理的错误消息：

在构建代理程序上预期：已成功执行

在构建管道中使用Browser.wait（）时失败，但在本地计算机上可以正常工作
