在JavaScript量角器中使用browser.wait（）

Question

Is it a good approach to use browser.wait() for each and every element in javascript-protractor? Is their any other better approach?

Answer 1

browser.wait() You provide an Expected Condition function for Protractor/WebDriverJS to execute and wait for the result of the function to evaluate to true. Protractor would continuously execute the function and stop once the result of the function evaluates to true or a configurable timeout has been reached.

browser.wait(EC.textToBePresentInElement(element(by.binding('myvar')), "expected"), 5000, "Text is not something I've expected");

var EC = protractor.ExpectedConditions;

var anyTextToBePresentInElement = function(elementFinder) {
  var hasText = function() {
    return elementFinder.getText().then(function(actualText) {
      return actualText;
    });
  };
  return EC.and(EC.presenceOf(elementFinder), hasText);
};

Answer 2

If you want to have some wait before finding each element then you should go with implicit wait..

description for implicit wait

If not on each find element then if you are using wait with some condition like wait for element/ element to be clickable ( Expected conditions) or like page to contain something[smart wait] then its good l, Else its not good idea to implement hardocded wait[ browser.sleep()].
