如何使用量角器在filepicker中上传文件？

这是HTML代码：

<input type="file" class="fileUploadInput" name="fileUpload" id="fileUploadInput" accept="application/msword,application/pdf,text/plain,application/rtf,application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/vnd.oasis.opendocument.formula" multiple="multiple" title="Choose File">

这是我的代码：

 browser.wait(function(){
            return element(by.id('.filepicker_dialog_container')).isPresent();
        }).then(function() {
            browser.driver.switchTo().frame('.filepicker_dialog');
        }).then(function(){
            var fileToUpload = '/home/raghavendra/Desktop/f0657c76d96b9ddab5562b8391297dbbb01488fec4e79a4c13195aea.doc';
            var absolutePath = protractor.basePath.resolve(__dirname, fileToUpload);
            $("#fileUploadInput").sendKeys(absolutePath);
});

我正在这样做，现在没有任何错误，但是它没有上传文件。弹出窗口现在没有关闭。

这是我完整的代码：

  var path = require('path');
var ptor = browser,
    driver = browser.driver;

describe('Hirealchemy roles', function() {

    it('while clicking filepicker icon', function () {


        $('.icon-people').click();
        browser.sleep(5000);
        browser.driver.findElement(By.xpath('/html/body/div[4]/div/ng-view/div/div/div[2]/' +
                                            'section/div/div/div[1]/form/div[2]/input')).sendKeys(group_name);
        browser.sleep(5000);
        element.all(by.css('.btn.btn-main')).click();
        browser.sleep(5000);

        browser.wait(function(){
             return element(by.id('filepicker_dialog')).isPresent();
        })
            .then(function(){
                ptor.switchTo().frame('filepicker_dialog');
            })

            .then(function(){
                 var fileToUpload = '/home/raghavendra/Desktop/50_resumes/f0657c76d96b9ddab5562b8391297dbbb01488fec4e79a4c13195aea.doc';
                 var absolutePath = path.resolve(__dirname, fileToUpload);
                 driver.findElement(By.id('fileUploadInput')).sendKeys(absolutePath);
            })

            .then(function(){
                ptor.switchTo().defaultContent();
            })

            .then(function(){
                browser.wait(function(){
                    var deferred = protractor.promise.defer();
                    element(by.id('filepicker_dialog')).isPresent()
                        .then(function(present){
                            deferred.fulfill(!present);
                        });
                    return deferred.promise;

                });
            });
    });
})

该代码有效。
