对于量角器中的可见元素,isDisplayed返回false

标签: javascript html css css3 protractor

编辑#4 :突破!

我开始递归地遍历父节点,并返回与下面相同的值。其中一个父级(内部mat-drawer-container)也为isDisplayed返回了false(其他所有父级都返回true,这似乎很奇怪)。

查看该节点,结果发现它是网站上唯一具有 display: contents 的CSS的标签。删除该内容会导致所讨论的按钮(其下面的所有其他按钮)为isDisplayed返回true。哎呀,量角器甚至可以单击该按钮,我可以在浏览器中看到预期的结果。

现在我想问题仍然存在:这是预期的行为还是错误?它并不像显示祖先那样简单:应用了内容;我将其直接应用于rb-container,而量角器仍然能够找到该按钮。


我是第一次在Protractor中进行端到端测试,并且在尝试测试按钮是否可见时遇到了一个问题;尽管button元素位于DOM中并且可见,但isDisplayed返回false,而我的断言失败。

这是失败的初始断言:

expect(element(by.css("mat-drawer-content rb-container rb-fab-button[data-qaid='create-button'] > button")).isDisplayed()).toBe(true);

(是的,选择器是一团糟,但我无法控制HTML。)

我使用了很长的browser.sleep()间隔来基本上将浏览器暂停在适当的位置,因此我可以使用开发工具来检查人类可见的元素,而CSS使我相信应该将其检测为可见

搜索答案和/或错误无济于事后,我在控制台上记录了一些信息,这仍然使我相信isDisplayed应该返回true:

[ 编辑#2,#3:记录了有关rb容器的所有直接子对象的更多信息;根据量角器,只有一个节点是“可见的”。]

  let selector = element.all(by.tagName("mat-drawer-content")).get(0).all(by.css("rb-container > *"));

  selector.count().then(function(selCount) {

    for (let match = 0; match < selCount; match ++) {

      browser.sleep(1000).then(() => {
        let elm = selector.get(match);

        console.log("\n >> " + match + "]");

        elm.getTagName().then(tag => { console.log("tag name:", tag); });
        elm.getCssValue("visibility").then(vis => { console.log("visibility:", vis); });
        elm.getCssValue("display").then(disp => { console.log("display:", disp); });
        elm.getCssValue("opacity").then(opa => { console.log("opacity:", opa); });
        elm.getCssValue("overflow").then(ov => { console.log("overflow:", ov); });
        elm.getAttribute("hidden").then(hid => { console.log("hidden:", hid); });
        elm.getAttribute("class").then(c => { console.log("class:", c)});
        elm.getSize().then(size => { console.log("size:", size); });
        elm.getCssValue("position").then(ov => { console.log("position:", ov); });
        elm.getLocation().then(loc => { console.log("location:", loc); });
        elm.isPresent().then(pres => { console.log("isPresent:", pres); });
        elm.isDisplayed().then(disp => { console.log("isDisplayed:", disp); });
      });

    }

  });

这是我看到的记录:

在未设置任何隐藏属性,显示值不为“ none”,可见性设置为“ visible”且尺寸尺寸不为零的情况下,我希望isDisplayed返回true。

看看节点4,这是isDisplayed为其返回的唯一子元素,并将其与节点2(我尝试访问的rb-fab-button元素)进行比较,这很有趣。我可以看到的唯一明显区别是rb-fab-button的位置是绝对的;但是,其他静态放置的元素也为isDisplayed返回false。

我想念什么吗?我愿意检查CSS的可见性,但是下一个测试是单击该按钮,如果该元素不可见,则会出错。
