使用 BeautifulSoup 查找测试用例和结果

Question

我需要一种好方法来查找所有测试用例的名称以及 html 文件中每个测试用例的结果。我是 BeautifulSoup 的新手，需要一些好的建议。

首先我已经这样做了，使用 BeautifulSoup 读取数据并对其进行美化并将数据放入文件中：

from bs4 import BeautifulSoup
f = open('myfile','w')
soup = BeautifulSoup(open("C:\DEV\debugkod\data.html"))
fixedSoup = soup.prettify()
fixedSoup = fixedSoup.encode('utf-8')
f.write(fixedSoup)
f.close()

当我在文件中检查美化结果中的部分时，它会如下所示（该文件包括 100 个 tc 和结果）：

<a name="1005">
  </a>
  <div class="Sequence">
   <div class="Header">
    <table class="Title">
     <tr>
      <td>
       IAA REQPROD 55 InvPwrDownMode - Shut down communication (Sequence)
      </td>
      <td class="ResultStateIcon">
       <img src="Resources/Passed.png"/>
      </td>
     </tr>
    </table>
    <table class="DynamicAttributes">
     <colgroup>
      <col width="20">
       <col width="30">
        <col width="20">
         <col width="30">
         </col>
        </col>
       </col>
      </col>
     </colgroup>
     <tr>
      <th>
       Start time:
      </th>
      <td>
       2014/09/23 09-24-31
      </td>
      <th>
       Stop time:
      </th>
      <td>
       2014/09/23 09-27-25
      </td>
     </tr>
     <tr>
      <th>
       Execution duration:
      </th>
      <td>
       173.461 sec.
      </td>
      *<th>
       Name:
      </th>
      <td>
       IAA REQPROD 55 InvPwrDownMode - Shut down communication
      </td>*
     </tr>
     <tr>
      <th>
       Library link:
      </th>
      <td>
      </td>
      <th>
       Creation date:
      </th>
      <td>
       2013/4/11, 8-55-57
      </td>
     </tr>
     <tr>
      <th>
       Modification date:
      </th>
      <td>
       2014/9/23, 9-27-25
      </td>
      <th>
       Author:
      </th>
      <td>
       cnnntd
      </td>
     </tr>
     <tr>
      <th>
       Hierarchy:
      </th>
      <td>
       IAA.  IAA REQPROD 55 InvPwrDownMode - Shut down communication
      </td>
      <td>
      </td>
      <td>
      </td>
     </tr>
    </table>
    <table class="StaticAttributes">
     <colgroup>
      <col width="20">
       <col width="80">
       </col>
      </col>
     </colgroup>
     <tr>
      <th>
       Description:
      </th>
      <td>
      </td>
     </tr>
     <tr>
      <th>
       *Result state:
      </th>
      <td>
       Passed
      </td>*
     </tr>
    </table>
   </div>
   <div class="BlockReport">
    <a name="1007">

在这个文件中，我现在想找到关于“名称”和“结果状态：”的信息。如果检查美化结果，我可以看到标签“名称：”和“结果状态：”。希望可以使用它们来查找 testCase 名称和测试结果......所以打印输出应该是这样的：

 Name = IAA REQPROD 55 InvPwrDownMode - Shut down communication 
 Result = Passed
 etc

有谁知道如何使用 BeautifulSoup 做到这一点？

Answer 1

使用html from your second Pastebin link，代码如下：

from bs4 import BeautifulSoup

soup = BeautifulSoup(open("beautifulsoup2.html"))


names = []
for table in soup.findAll('table', attrs={'class': 'Title'}):
    td = table.find('td')
    names.append(td.text.encode("ascii", "ignore").strip())

results = []
for table in soup.findAll(attrs={'class': 'StaticAttributes'}):
    tds = table.findAll('td')
    results.append(tds[1].text.strip())

for name, result in zip(names, results):
    print "Name = {}".format(name)
    print "Result = {}".format(result)
    print

给出这个结果：

Name = IEM(Project)
Result = PassedFailedUndefinedError

Name = IEM REQPROD 132765 InvPwrDownMode - Shut down communication SN1(Sequence)
Result = Passed

Name = IEM REQPROD 86434 InvPwrDownMode - Time from shut down to sleep SN2(Sequence)
Result = PassedUndefined

Name = IEM Test(Sequence)
Result = Failed

Name = IEM REQPROD 86434 InvPwrDownMode - Time from shut down to sleep(Sequence)
Result = Error

我添加了encode("ascii", "ignore")，否则我会得到UnicodeDecodeError。请参阅 this answer 了解这些字符如何最终出现在您的 html 中。
