使用For-Loops干燥量角器点击测试 [英] DRYing up protractor clicks tests using a For-Loops

问题描述

问题：
如何点击 ul>中的每个链接？ li a 来自一次测试？

问题：此测试正在通过;但是，它没有点击链接。我知道这是因为它没有重定向或等待2000ms。

Problem: this test is passing; however, it isn't clicking on the links. I know this because It isn't redirecting or waiting 2000ms.

测试：

  it("should have proper page linking to all footer link", function() {
      browser.driver.sleep(2000);
      browser.ignoreSynchronization = true;
      //creates an array of strings of all the menu items
      var titles = element.all(by.css('.leftMenu.first .submenu li a'))
          .map(function(elm) {
              return elm.getText().then(function(text){
                 return text;
              });
          });

      //iterates through the links via titles array
      for (var i = 0; i < titles.length; i++) {
          // creates a link via selection of cssContainText of the titles array
          var link = element(by.cssContainingText('.submenu li a', titles[i]));

          //click event
          link.click().then(function() {
              browser.driver.sleep(2000);
              //currently arbitrary expectation but will pass
              expect(browser.driver.getTitle()).toBe('welcome to: ' + title[i]);
          });

      }

  });

推荐答案

上述答案和方法似乎都采用了同步方法，所以我想提供我找到的使用标准异步量角器方法的相同问题的解决方案。

the above answers and approaches all seem to take a 'synchronous' approach, so I'd like to offer the solution I found for the same issue which uses the standard asynchronous protractor approach.

在此示例中，页脚链接是文本链接，例如关于，联系人等 - 并且这些链接映射到诸如/ about和/ contact等的URL。

In this example, the footer links are text links such as 'ABOUT', CONTACT', etc. - and these map to URLs such as '/about' and '/contact', etc.

编辑：ptor之前是从protractor.getInstance（）定义的;

ptor is defined earlier from protractor.getInstance();

it('should have a working set of footer links to internal pages', function() {
  // element.all( -your selectors- )
  // .then() is passed an ARRAY of element finders 
  element.all(by.css('.footer .nav .links')).then(function(elems) {

    // for each element .getText() returns a promise
    var txts = elems.map(function(elem) {
      return elem.getText().then(function(txt) {
        if(txt != ''){
          return txt;
        }
      });
    });

    // txts is now an ARRAY of promises
    // When they are ALL fulfilled the loop below is run
    protractor.promise.all(txts).then(function(links) {
      for (var i=0; i<links.length; i++) {
        // reset browser back to page of interest
        // the home page in this case
        browser.get('/');

        // get a fresh instance of the element and click it
        // attempts to click pre-created element list
        // will result in 'stale' elements references as pages
        // are being navigated
        element.all(by.css('.footer .nav .links')).get(i).click();

        // expectation of navigation
        expect(ptor.getCurrentUrl()).toContain(links[i].toLowerCase());
      }
    });

  });

});
