Question

我使用量角器来测试this project，here可以看到。

以下是测试：

将延迟设置为2000毫秒。
将持续时间设置为4000毫秒。
单击演示按钮。
时间并等待加载指示器（微调器）。
写下等待的时间（或真实测试的断言）。

然而，browser.wait似乎没有返回。

代码：我认为应该有效......

//Inside it("test", function() {
set(delayInput, 2000); //custom sauce but it sets the element
set(durationInput, 4000); //custom sauce but it sets the element
var tStart = 0;
var spinner = element(by.css('.cg-busy.cg-busy-animation.ng-scope'));
var waitForMe = function() {
    return spinner.getAttribute('class')
        .then(data => data.includes('ng-hide') === false);
}
demoButton.click()
    .then(() => tStart = Date.now());
browser.wait(waitForMe, 4000)
    .then(() => console.log(Date.now() - tStart));

代码：也许其他应该有用的东西......（小差异）

demoButton.click()
    .then(() => tStart = Date.now());
    .then(() => 
        browser.wait(waitForMe, 4000)
            .then(() => console.log(Date.now() - tStart))
    );

代码：定位器和自定义调整

//btw, I can see the test correctly execute so I am actually getting the elements.
var delayInput = element(by.model('delay')),
    durationInput = element(by.model('minDuration')),
    demoButton = element(by.css('.btn')),
    spinner = element(by.css('.cg-busy.cg-busy-animation.ng-scope')),
    set = function(elem, data) {
        elem.clear();
        elem.sendKeys(data);
    };

我不断收到Failed: Wait timed out after 4056ms，这可能意味着spinner始终包含'ng-hide'。但是，如果我检查网页并手动运行测试，那就是＆＃39; ng-hide＆＃39;消失（这是有道理的）。所以，我认为这与承诺或阻止功能有关，但我不确定。

修改

代码：我也试过......

var EC = protractor.ExpectedConditions;
browser.wait(EC.visibilityOf(spinner), 4000)
    .then(() => console.log(Date.now() - tStart));

我尝试将持续时间和超时时间延长到15000毫秒。这个游戏我有以下错误：

Failed: Cannot assign to read only property 'stack' of Timed out waiting for Protractor to synchronize with the page after 11 seconds. Please see https://github.com/angular/protractor/blob/master/docs/faq.md
    While waiting for element with locator - Locator: By(css selector, .cg-busy.cg-busy-animation.ng-scope). 
    The following tasks were pending:
     - $timeout: function (){
                        tracker.durationPromise = null;
                    }

量角器：browser.wait不在element.click（）之后工作
