等待元素存在而没有错误 [英] wait for element present without error

问题描述

有没有一种方法可以在夜表中调用waitForElementPresent，而不会错误地指出该元素是否不存在?

is there a way to call waitForElementPresent in nightwatch without erroring out if the element is not there?

现在，如果将false作为第三个参数传递，您仍然会看到错误.理想情况下，我想要一个等待元素的函数，如果找不到元素，则返回该函数.

Right now, if you pass in false as the third parameter, you still see an error. Ideally, I would like a function that waits for an element, and returns if it didn't find the element.

推荐答案

您可以做到:

  Browser.waitForElementPresent('@element',3000,false, function(result){
    If(result.value === true){
    // test if element present
    }else{
    // test if element not present
    }
  })

从第一天开始，我就这样做了，这段代码的问题是守夜人会将失​​败的测试视为通过的测试，如您所见，上面的代码处理两个结果值.

Since the day one, i did this and the problem with this code is nightwatch would count a failed test as a passed test,as you see above code handle both result value.

所以我建议让夜表本身返回错误，为差值编写差值函数.

So i recommend let the nightwatch return error itself, write difference function for difference value.
