nightWatch：等待没有pass/fail结果的元素

Question

相关问题：

null

browser.waitForElementNotPresent(
  "cssSelector_For_HTML_afterAJAXComplete",
  10000 //timeout
);

不过，这为我的测试添加了一个额外的断言，并人为地使报告的测试计数大于所需的值。

有什么想法吗？

好吧，我一起砍了点东西。我基本上使用browser.execute(function，params，callback)在selenium中将javascript发送到控制台

  function waitForElement_NoPassFail(selector, timeout){
    browser.execute(function(selector, timeout, done){
      let intervalId;
      var p1 = new Promise(function(resolve, reject){
        intervalId = setInterval(function(){
          let itemArray = document.querySelectorAll(selector);
          if(itemArray.length == 1){
            clearInterval(intervalId);
            resolve(true); //element found
          } else if(itemArray.length>1){
            reject(false); //too many elements found, because of ambiguous selector
          }
        }, 100);
      });
      var p2 = new Promise(function(resolve, reject){
        setTimeout(reject,timeout, false); //timeout reached
      });
      return Promise.race([p1, p2]).then(function(result){
        done(result);
      });
    },
    [selector, timeout],
    function(result){
      if(!result){
        throw "Element: " + selector + " wasn't found after " + timout + " ms.";
      } else {
        console.log("Element found within timeout limits.") //doesn't trigger assert=ok
      }
    });
  };

  waitForElement_NoPassFail(
    "cssSelector_that_Is_Valid_after_AjaxIsComplete",
    10000 //timeout
  );

可以通过各种方式对其进行扩展，例如支持XPath。您可以使用nightwatch全局变量来执行等待时的元素检查频率。如果你需要帮助，写一篇评论。
