PS:这次用公司的项目来练手,希望公司不会起诉我,因为我绝对是抱着学习的态度,没有任何恶意。仅供交流学习。
该项目是基于SharePoint平台所开发的门户网站,为了切身感受一下Selenium 2.0我决定自己动手写一个自动化测试用例,而不是通过录制的方式,以加深我对一些web操作的理解。
我设计的测试用例是:检查Staff Spotlight中所包含的item对应三级页面显示的信息是否正确。具体逻辑是,在英语浏览器下检查后台list中英语Column的value和三级page中对应Column的value是否一致,在日语浏览器下检查后台list中日语Column的value和三级page中对应Column的value是否一致,如果是英语浏览器下后台list中没有勾选“English Ready”项,则在三级page中显示日语Column的value。
三级page如下:
点击页面右上角的“Edit Item”按钮可以跳转到后台list中相应的item编辑页面;点击上方的“日本语”按钮可以进行英语和日语的语言切换,点击“日本语”将切换到日本语,再点击“English”将切换到英语。
我们本次要取的页面元素就是Department,Location,Title以及Join Date的页面value。然后点击“Edit Item”按钮跳转到后台item编辑页面,按“F12”,找到对应要获取的后台元素值:
获取到对应的Column的value所在页面的元素,然后获取页面上显示的值,将其与三级page上的value按我们之前说过的逻辑进行比对,如果一样,测试通过;如果不一样,测试失败。
代码如下:

Encoding.Default)){try{sw.Write(ex);}catch (Exception ex1){WriteLog(ex1);}finally{sw.Close();fs.Close();}}}}else{using (FileStream fs = new FileStream(logUrl, FileMode.CreateNew)){using (StreamWriter sw = new StreamWriter(fs, Encoding.Default)){try{sw.Write(ex);}catch (Exception ex1){WriteLog(ex1);}finally{sw.Close();fs.Close();}}}}}} }
这里我创建一个类,用来存储三级page以及后台list中获取到的Staff item的信息:
using System; using System.Collections.Generic; using System.Linq; using System.Text;namespace mySelenium {class StaffSpotlight{public string Department { get; set; }public string Location { get; set; }public string Title { get; set; }public string EnTitle { get; set; }public string JoinDate { get; set; }} }
按F5进行测试,结果如下:
测试通过。
覆盖多浏览器在Selenium也是很容易实现的,只需要把IE打开方法改用为指定浏览器所对应的打开方法:
IWebDriver driver = new InternetExplorerDriver();
把这句换了,之后的步骤对应做些修改即可。
自动化测试从某些方面讲确实是一劳永逸的,但是有很多时候自动化测试是完全没有必要的,尤其是项目周期很短的情况下,自动化的封装应该更偏向于具有普遍性的可复用过程,而不是业务逻辑。
有时候,产出决定付出。我们没必要为了一个两三月交付的项目写一堆自动化测试用例,否则得不偿失。自动化测试应该更偏向于长期上线、持续迭代的项目展开!否则最后失落感是一定有的。
