我没有出现原生硒错误，例如``找不到元素''或``元素不可点击''，相反，我在量角器中收到超时错误

Question

I'm working in Protractor cucumber framework.I do not get native selenium errors such as 'Element not Found' or 'No Such Element Found' or 'Element is not clickable' if the element is not found in page or not clickable.Instead i get "TimeoutError: Wait timed out after 10002ms"

Only if i get these errors I will come to know i have made some mistake in my element xpath or I have tried to click a disabled button etc.

Generic error like time out does not help me fix the failed test cases easily.

Below is my code.contactPage.js is the implementation.util.js is some helper methods in my framework

File contactPage.js

  var contact = element(by.xpath("//p[contains(text(),'Contact Me')]"));

   function clickUserGuide() {
   return util.isDisplayed(contact, 10000).then(() => {
    return util.clickElement(contact, 10000);
});

File util.js

function isDisplayed(element, milliseconds) {
return browser.wait(EC.visibilityOf(element), milliseconds).then(() => {
    return element.isDisplayed();
  });
};
function clickElement(element, milliseconds) {
 return browser.wait(EC.visibilityOf(element), milliseconds).then(() => {
    element.click();
    return true;
 });
}; 
}

The reason why you are getting TimeoutError: Wait timed out after 10002ms is because of the method browser.wait(EC.visibilityOf(element), milliseconds) you are using.

The method doesn't have a fail "hard" like the No Such Element Found , it just keeps waiting for the element to match the expected condition, in your case you are waiting for:

1. the element is be displayed
2. AND the height and width to be greater than 0

If this doesn't happen in the given amount of seconds the condition fails with a message that the element couldn't match the condition within the given time.

What happens is you use browser.wait(EC.presenceOf(element), milliseconds) , is the element really present in the DOM?
