isElementPresent 的简单量角器测试因不支持的定位器策略而失败

本文介绍了isElementPresent 的简单量角器测试因不支持的定位器策略而失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我的测试:

it('should allow login', function() {
  browser.get('index.html');

  $('#username').sendKeys('administrator');
  $('#password').sendKeys('password');
  $('#login').click();

  var logout = $('#logout');
  expect($p.isElementPresent(logout)).to.eventually.be.true;
});

但这会出错:

Error: Unsupported locator strategy: click
  at Error (<anonymous>)
  at Function.webdriver.Locator.createFromObj (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/locators.js:97:9)
  at Function.webdriver.Locator.checkLocator (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/locators.js:111:33)
  at webdriver.WebDriver.findElements (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/webdriver.js:805:31)
  at webdriver.WebDriver.isElementPresent (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/webdriver.js:787:29)
  at Protractor.isElementPresent (/usr/local/lib/node_modules/protractor/lib/protractor.js:476:22)
  at /Users/pschuegr/wt/client/e2e/login_test.js:26:15

奇怪的是，它指向的是 isElementPresent 行，而不是点击的那一行.我对 webdriver 很陌生，如果我错过了一些明显的东西，我深表歉意.我正在使用 mocha 框架(这意味着量角器的金丝雀版本)运行，fwiw.

Strangely, it points to the isElementPresent line, rather than the line with the click. I'm pretty new to webdriver, so apologies if I missed something obvious. I'm running using the mocha framework (which means the canary version of protractor), fwiw.

任何想法表示赞赏.

推荐答案

$('#logout') 是一个 WebElement.isElementPresent 采用定位器，例如 by.css

$('#logout') is a WebElement. isElementPresent takes a locator, like by.css

$('#username').sendKeys('administrator');
$('#password').sendKeys('password');
$('#login').click();

var logout = by.css('#logout');
browser.wait(function() { return $p.isElementPresent(logout); }, 8000);
expect($p.isElementPresent(logout)).toBeTruthy();
